jollyhawley Posted July 28, 2009 Share Posted July 28, 2009 I was cleaning out my classroom closet today when i stumbled upon a package of 28 small (~1 cm in diameter) glass discs. On one side they act as gold tinted mirrors. When I look through them, it shows objects as different shades of color depending on how the light hits it. The outside of the package says "Spectra-Physics Optics". Any ideas on what they are? Thanks! Link to comment Share on other sites More sharing options...
Cap'n Refsmmat Posted July 28, 2009 Share Posted July 28, 2009 Try stacking two of them together and rotating them relative to each other. Then look through. If you see it getting lighter and darker as you rotate, they're probably just polarized lenses. Link to comment Share on other sites More sharing options...
jollyhawley Posted July 28, 2009 Author Share Posted July 28, 2009 They're not polarized lenses... I just tried it. All putting the two of them together does is making the color tint darker. Rotating one relative to the other makes no difference. Link to comment Share on other sites More sharing options...
