Description

Somewhat parametric, kinematic mirror/lens mount for steering optics.

en.wikipedia.org/wiki/Mirror_mount

It contains a living hinge in one corner and two magnets in the adjacent corners. These magnets are attracted to a pair of set screws used to adjust the mirror angle. The size of the magnets match those in the makerbot platform.

There are both imperial and metric mounting versions. Imperial uses a 1/4" hole, while metric uses a 6mm hole to match the optical benches. Alternatively if you need a cheap optical rail you can use T-slot extrusion like I did in the photos.

I assume you're asking about the mounting to the t-slot extrusion. It's not the best method, it simply uses a large head screw that can fit within the extrusion (I was using mcmaster carr's 47065T142). I would tighten the screw just enough so that it provided significant friction when slid into the extrusion. The problem of course is that you can't continue to tighten the screw after it has been inserted into the extrusion.
hello, can you expalin better how does the rail junction work?
 Awesome thanks!

Instructions

Print, cleanup edges, press fit two M3 nuts, press fit two 3x3x3mm magnets, and screw in two M3 mirror adjustment screws. Some superglue may help keep the magnets in place.

Brilliant! We are just putting the finishing touches on an optical rail system for Open Beam. Sweet mirror mount -- thank you! We are definitely going to use it.
Thanks, I'd been sitting on the design for a while.. I noticed your work and realized that I should post this sooner rather than later so that hopefully you can use or modify this design rather than starting from scratch. I'll upload my Michelson interferometer soon :)
 Awesome thanks!
