JoshTheEngineer | How To: DIY Laser Schlieren @JoshTheEngineer | Uploaded December 2016 | Updated October 2024, 1 hour ago.
In this video I will show you how to build a Schlieren setup using a laser pointer. There were quite a few questions on my first How To video, so I figured I would post a guide here.
I use a little red laser pointer as my light source. To get the beam to diverge, I bought a plano-convex lens from Thorlabs (part number LA1213). Everything else in the setup is the same as the other setup.
