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.

Re: Microstar IV Analyzer
That is also very neat and tidy. Looks like original equipment.

Re: Microstar IV Analyzer
That's stunning. Rotating intermediate polarizers tend to be pretty darned expensive and scarce on the secondary market--I've been iterating a design for one for my z6 but nothing nearly as beautiful or intricate as this.
Re: Microstar IV Analyzer
Well done. I can appreciate the head scratching that went into that not to mention the printing and testing.
Proper job!

That’s a brilliant add on for the scope Brian . Must get one of those 3D printers!
