This is an lens holder for optical experiments.

This component is part of the Open-source optics project, whose goal is to radically reduce the cost of scientific optical hardware: by the Michigan Tech's Open Sustainability Technology Research Group.

For similar see the Open-Source Lab How to Build Your Own Hardware and Reduce Research Costs


This open-source lens holder is designed to hold a standard 1 inch diameter lens on a smooth 8mm diameter rod.

Use the OpenSCAD files to customize it for your application, print on your favorite open source 3-D printer and enjoy. Included are the main holder and thumb screw.

If you need the base go to http://www.thingiverse.com/thing:28133

Nice design! The vertical rod is optical post, or are you planning on precision rod or something from McMaster?

I have been trying to do something similar, using aluminum angle from the home store as an optical rail. I got distracted this summer, and haven't gotten my (not so awesome) designs up on Thingiverse yet, but I am happy to see someone else thinking on these lines.

In the meantime, if you are inte
rested, you can see some of the mounts I printed in this video (http://youtu.be/fgCn6SYeVT0)http://youtu.be/fgCn6SYeVT0) describing a schlieren photography rig I set up. You can see better quality schlieren video here (http://youtu.be/bGskL2wdQ54)http://youtu.be/bGskL2wdQ54).

Thanks !

We made it for just standard smooth rod - the same used for RepRaps.

Your schlieren setup - using angle extrusion for an optical rail - is brilliant - I will look forward to seeing them up. Most of the standard physics optics college experiments use only a rail that can go for over $100/ft that a
lone could make systems affordable for most schools and push the switch.

For our setup we are building a PL and a QE for solar cell research - so we are going to need everything to be moveable in x and y - shoudl have the magnetic base plans up next week along with the automated filter wheel.

a couple of groups job on the wagon we should have an ultra-low cost open optics setup ready for anyone that needs it by the time school starts.

Good Idea!!!

Lab suppliers are obscene with their prices.

Thanks - agreed completely!
