Microstar IV Analyzer
Posted: Thu Sep 24, 2020 4:49 am
The original analyzer box for the Microstar IV seems hard to come by, and I've been using a simple PVA polarizing disk inside the head for a while to get a poor man's polarizing microscope.
I've been looking for a more convenient way to house the analyzer which would allow me to rotate it and remove it from the optical path as needed. I ended up designing a 3D printed housing that copies the dovetail design of the Microstar itself and allows me to clamp it into the optical path.
The polarizer sits on a swing arm that can be moved in and out of the optical path as needed. The arm itself is on a hinge and is held in the open/close position with magnets. The polarizing disk sits on a geared wheel that engages with a handwheel when the polarizer is enabled, allowing it to be turned.
I've created a video of the assembly and usage of the polarizer box in a youtube video for those interested.
