Lego Optics Lab: Mirror/Filter Holder

Jul 06 2015 | comment(s)

I’ll demonstrate how I built a simple mirror or filter mount out of Lego. This mount can then be attached to a pan and/or tilt mechanism.

Also see my previous article to see how I built a large lens holder for my Lego optics lab.

Parts needed

1 Plate 2 X 8
2 Technic Beams 1 X 2
2 Arm section with pin and two fingers

Lego Optics Lab: Large Lens Holder

For my Lego Optics Lab I have so far built a beam splitter, and a small lens holder. The beam splitter article got a link on io9 (my name is misspelled) and on Scientific American.

Lego Optics Lab: Small Lens Holder

Jun 22 2015 | comment(s)

In my previous article, I started building a Lego optics lab with a dichroic prism I salvaged from an old computer projector that I took apart (I used the prism to build a beam splitter). I also salvaged several lenses, mirrors, and filters. To continue the Lego Optics Lab project I’ll demonstrate how I built a lens holder for the several small lenses from the projector. My lens holder uses mostly standard Lego parts except for the shock absorber brick.

I finally took apart a broken computer projector. Some of the optics were burned or broken but I managed to salvage several lenses, mirrors, filters, and a curious little glass cube.
