This simulation shows a spatially- and temporally incoherent wave emitter that consists of around 100 individual wave sources. The sources are continuous but all have a slightly different emission wavelength. This results is the emission field and intensity distributions shown in the video.

The simulation was made using a python script supplied by @DiffractionLimited
The image files for the simulation can be downloaded here:

The diffraction inside the lens is probably due to the fact that the refractive index gradient is not exactly correct. The total gradient is approximated from 5 linear gradients instead of 1 smooth circular gradient. This is probably the reason for the observed interference pattern observed.

$Maskless Wafer Stepper Part1: Optics Ive been planning to make a maskless wafer stepper for a long time. In the last few months, I finally found the time! This video is the first of 3 videos on the design- and build process. It discusses the optical aspects of the machine. 0:00 General intro 0:38 About Wafer steppers in general 1:12 Meta surfaces and flat optics 2:00 Principle and advantages of a maskless wafer stepper 4:36 Projection optics 6:47 Global layout of the machine 8:50 System overview I hope to make micro optics with this machine in the near future. By the way, not the standard meta surfaces, because the resolution will be too limited for that, but meta surfaces that combine both refractive and diffractive functionality. Currently Im still in the building process of the machine and the software. I have taken the liberty of using a few short clips in my video.
