ThorlabsThis video demonstrates a complete procedure for aligning two FiberPorts on a FiberBench. The procedure takes into account the coupled functionality of the various adjustment screws, such as the ZΘ screws. Adjusting any of the three ZΘ screws individually affects both the angular orientation and Z-axis position of the lens. When all three ZΘ screws are adjusted as a set, it is possible to move the lens such that the final position corresponds to only a change in angular orientation or shift in position along the Z-axis.
For example, adjusting each of the three ZΘ screws by the exact same amount in the same direction translates the lens along the Z-axis without affecting the lens' angular orientation. The different techniques used to complete this and other adjustments are shown during the demonstration, so that this alignment procedure can be customized according to preference.
Before aligning the FiberPorts to one another, the lens in each should be pre-aligned to collimate light from a coupled optical fiber. The pre-alignment step should not be necessary if the FiberPort has not been used, since FiberPorts are provided pre-aligned. The alignment procedure begins by tuning the X-axis and Y-axis adjusters and progresses to the ZΘ adjusters. To avoid complicating the alignment procedure, it is recommended that the X- and Y-axis adjuster positions are not changed after beginning work with the ZΘ adjusters.
The optical power collected by the coupling fiber is used to monitor the progress of the alignment procedure. However, it should be noted that a drop in power after an adjustment may not indicate a misstep in the procedure. Instead, the drop may correspond to a local minimum en route to a global maximum. This demonstration provides tips for interpreting and investigating the progress of the alignment, as well as advice for making consistent adjustments.

An approach for making this coupling is demonstrated using a CF-flanged fiber optic feedthrough and a port on a CF-flanged tee. Since the quality of the vacuum seal and the time required to pump the vacuum system down to operating pressure depend on more than just ensuring the bolts are tightened correctly, this demonstration also highlights several practices for working with vacuum components and systems that can help achieve good results.
Damage to the knife edge, an aggressive approach to tightening the bolts, and reusing gaskets can all result in leaky CF vacuum couplings. The techniques demonstrated in this video reduce the risk presented by these factors, which are all related to the limited malleability of the metal gasket. It is important that the knife edges are in pristine condition, since the gasket is not soft enough to fill narrow or abrupt features, such as a nick in a knife edge. An approach of gradually and iteratively tightening the bolts is effective in maintaining a uniform thickness of the gasket around its circumference, while tightening each bolt all at once can result in thickness variations in the gasket that are difficult or impossible to flatten. This is a consequence of the metal gasket’s limited ability to flow and can result in gaps between the gasket and knife edges. Using a new gasket is always recommended. Even a gasket that was only partially compressed during a previous use may not be malleable enough, when reused, to conform to the contours of the knife edges. This is because compression has the effect of strain (work) hardening the metal.
While a leaky vacuum connection can result in time lost to leak checking and re-opening the vacuum system to locate and fix the problem, productive work can also be delayed as a result of broken or malfunctioning components in or attached to the chamber. Due to this, an overview of special considerations for handling and using fiber feedthroughs is also included in this video. ConFlat® is a registered trademark of Agilent Technologies, Inc.

The program acquires optical power measurements from the power meter as the rotation mount's angle sweeps through 180°, which is required to characterize a variable optical attenuator. Since this code uses libraries developed using the .NET framework, running this code requires Python.NET to be installed.
This tutorial implements the code specific to the K-Cube motor controller first, followed by the code for the power meter. The packages and classes required by both devices are identified, and the steps required to initialize and complete shutdown for both devices are shown. In addition, an approach is described for acquiring power readings and checking controller status while the motor is moving. The Python script is executed once after the K-Cube section of the code is complete, and a second time after the program is finished.
The K-Cube motor controller and power meter were automated in order to characterize the optical power transmitted through a pair of fixed, crossed linear polarizers when a rotating half-wave plate is located between them. As the half-wave plate rotates, the polarization orientation of the light transmitted by the output polarizer remains constant, while the transmitted power varies sinusoidally. Measurements of this transmitted optical power, as well as the corresponding rotation angles of the mount in which the half-wave plate is secured, are provided by the program.

One approach to finding the beam focus with respect to the fixture uses laser speckle.
During this demonstration, laser speckle is used to find focal points provided by lenses mounted in individual lens tubes. After locating the focus of each mounted lens, the distance between the focal point and the external shoulder of each lens tube is measured.
The mounted lenses are then used to construct a Keplerian beam expander, using a design in which empty lens tubes are inserted between the two mounted lenses. The required total length of the lens tubes separating the two mounted lenses is estimated using the previously measured distances to the focal points. This approach avoids tedious trial-and-error that can result when the beam expander is constructed by first guessing the required total lens tube length, and then iteratively measuring beam quality and adjusting the length until achieving the desired result.
A transmissive glass diffuser is used during this demonstration to create the speckle pattern. The size of the speckle is largest when the ground surface of the diffuser is at the focus, where the beam size is smallest. It is recommended that the beam is incident on the ground face of the diffuser. This allows direct measurement of the distance to the focus, without needing to take the diffuser's optical thickness into account. After assembling the beam expander, a shearing interferometer is used to fine-tune the collimation of the expanded beam.

There are different approaches to designing and building the foundation. Some result in optical setups that are more affected by vibrations and more likely to be misaligned when bumped. In addition, certain techniques used to assemble components can accidentally damage them.
Unfortunately, it is typically necessary to build the entire setup to observe the effects of different approaches, so evaluating the benefits and disadvantages of each can be difficult or time consuming. In addition, the existence of other approaches may not be obvious, since it can be easy to avoid thinking about components that are as familiar as posts, post holders, and bases. The techniques presented in this video are methods we have found useful and should provide a good starting point for working with optomech.
This demonstration shines a spotlight on these common building-block components and includes tips learned though long experience designing and working with them. The purpose and use of features that may have escaped notice, such as the relief cut on bases, the through hole in optical posts, and the benefits of washers are revealed. Guidelines for choosing post and post holder heights to increase mechanical stability are provided, as well as suggestions for avoiding damage to kinematic mounts when attaching a post. This video also demonstrates a potentially unexpected approach for mounting larger components, which uses two post holders, two posts, and a base.
Additional tips for avoiding unintended consequences and preserving the full adjustment height when bolting post holders to optical tables, bases, and breadboards are demonstrated in this Video Insight: youtu.be/HyUXsH1zuIk

Minimizing leak rates through this vacuum coupling requires the flat flange faces to be smooth and clean, as well as the O-rings to be malleable and undamaged. This video demonstrates methods for coupling and disconnecting KF flanged components and shares tips for handling, maintaining, and assembling these popular vacuum flanges. Vacuum systems that include KF flanges can generally support vacuum levels down to 10-8 Torr (1.33 x 10-8 mbar, 1.33 x 10-8 hPa). Note that while the flange type is identified as KF (or QR), flange sizes may be specified using functionally equivalent prefixes of KF, DN, or NW.
There are many benefits to using KF flanged components in vacuum systems, including a genderless design, standardized sizes, quick decoupling and reconnection times, and being relatively inexpensive. Many of these features are made possible by the elastomeric O-ring that serves as a gasket.
The effectiveness of the vacuum seal depends on several factors including the conditions of both flange faces and the O-ring, the compression applied to the O-ring, and the O-ring's history of temperature exposure and usage. Excessive amounts of compression (greater than 60%) and exposure to high temperatures increases the rate at which the O-ring develops compression set. Compression set is a term used to refer to permanent changes in the O-ring's shape, which includes stiffening of the elastomeric material. Inspecting the O-ring and flange surfaces as shown in the video, and then replacing damaged components and stiffened O-rings can optimize performance. The application of vacuum grease to an O-ring is also demonstrated, and guidance for determining whether or not to use vacuum grease is provided.

This can be enabled using the software development kit (SDK) provided with Thorlabs' scientific cameras. The use of the SDK to control the operation of a scientific camera is demonstrated using a custom Visual Studio® console application written in C#, as well as a setup that includes a scientific camera, light emitting diode (LED), LED driver, and PC.
The demonstration begins with a general overview of the setup, and then steps through the settings needed to configure the LED driver to pulse the LED five times while providing a TTL output signal each time. Pulsing the light source is one approach to limiting a sample's total light exposure, and the TTL signal can be used to synchronize image acquisition with the illumination of the sample. A cable couples the TTL hardware trigger to the camera.
A blank Visual Studio console application is then opened, and the code is explained as it is typed line-by-line. The program finds all available cameras connected to the PC and is used to select one, whose parameters the program will configure for the setup. The exposure time is set to be slightly less than the LED pulse duration, and a single image acquisition is specified to occur when a hardware trigger is received. Each image is saved to a file as a bitmap, and the total number of acquired images is limited to five. The demonstration concludes with the successful execution of the program, which results in five saved image files that were each taken during a separate flash of the LED.

This is because there are multiple variables that must be controlled during the alignment process. This demonstration divides the procedure into discrete steps and includes helpful tips for successfully positioning the mirror and light source. In addition, the dependence of the correct alignment on the mirror's geometry is discussed, and the typical effects of different misalignment geometries on the beam shape are shown on a viewing screen.
In this demonstration, the divergent output of an optical fiber and an OAP mirror are aligned so that the incident light and the collimated reflected beam travel in a plane parallel to the surface of the optical table. Because of this, an important initial step in the procedure is to set both the height of the source and the center of the mirror mount's bore at the height of the desired collimated beam. Then, an iterative approach is used in which the mirror is rotated to bring the plane of reflection parallel to the plane of the table, and the fiber's end face is moved to the mirror's focal point.

This tutorial for Thorlabs' Kinesis® software package provides step-by-step instructions for writing a program for a BBD300-series motor controller that moves the connected two-axis stage in a stepped, bidirectional raster scan pattern. The program is written using C#, the .NET framework, and the Visual Studio® development environment.
This tutorial builds on the foundation established by the previously released Video Insight, Visual Studio Project Setup and C# Programming - Kinesis BBD300 Series Controller ( youtu.be/eoN1IPD7XZc ). After providing a brief overview of different raster scan patterns and approaches, this demonstration quickly reviews some of the steps included in the Visual Studio Project Setup tutorial. This includes referencing libraries, configuring the project platform, and initializing the controller's chassis and two channels.
Three types of move methods are implemented. One is used to home a chosen stage axis, and another is used to move the stage to a specific position. The third implements a jog, which moves the stage along a particular axis by a specified step size. The raster scan is implemented by first moving the stage to an initial position, and then executing a series of jogs along the stage's X- and Y-axes. An example of debugging the code is shown, and the stepped, bidirectional raster scan is successfully executed.

This video describes two methods for building a manual polarimeter, the classical method and the rotating wave plate method, and then uses both to measure a laser beam's polarization state. [1] Both approaches provide measurement data that describe the polarization state in terms of the four Stokes parameters. This demonstration includes discussion of the relationships between the Stokes parameters and different polarization states, including linearly and circularly polarized light.
In this demonstration, polarization handedness is defined with respect to time and from a perspective of looking into the beam, back towards the source. This video illustrates this convention by visualizing a fixed viewing plane oriented perpendicular to the propagating beam. As the beam passes through the plane, the beam's instantaneous polarization vector traces out a shape on the plane. The shape is traced out as a function of time, and the direction in which the shape is traced corresponds to the handedness of the light. The shape itself is the polarization ellipse, which is a convenient and common way to describe light's polarization state. The relationship between the polarization ellipse and the Stokes parameters is also discussed.
Prior to filming, the transmission axes of the linear polarizers and wave plate used to build these polarimeters were oriented with respect to the table. The following are links to Video Insights demonstrating the described alignment procedures:
- Align a linear polarizer horizonal or vertical with respect to the table: youtu.be/W9pALZ5Z8ms - Align a linear polarizer at 45° with respect to the table: youtu.be/cqLPD5dL9zY - Align a wave plate's axis to be horizontal with respect to the table: youtu.be/P0asuzX4x-Q - Determine whether a wave plate's axis is fast or slow: youtu.be/XQwiPm5OtSk

This tutorial for Thorlabs' Kinesis® software package provides step-by-step instructions for using C# and the .NET framework to create a new Visual Studio® project and initialize connected devices, which in this case is a BBD300 series motor controller connected to a two-axis stage. A basic move sequence is then added to the program and used to test the execution of the code.
The demonstration begins with instructions for creating a new Visual Studio project and adding the required dynamic link libraries (DLLs). In this example there is one connected controller, and the program is written to execute its two-step initialization process, since the controller's chassis and channels must be initialized individually. Each channel corresponds to a different stage axis, and this program initializes one of the controller's two channels (axes). Custom velocity and position settings are specified for the move command, and instructions are included to perform the disconnect shutdown sequence after the move sequence is completed. Try-catch blocks are added to the code to provide instructions to the program in the case that an error is thrown by a method. Command and position status information is made available to the user, and status messages are printed to the PC's console screen.
These steps are used as the foundation of a program described in another Video Insight (youtu.be/CoDlTOEo-4w) that executes a stepped, bidirectional raster scan using the same controller and XY stage.
