Brewster "stack of plates" polarizer demonstrator

Brewster Angle "stack of glass plates" polarizer demonstrator...for optics students to show them (1) the zero in the reflectivity for 'p' polarization off a dielectric and (2) how it can be used to purify a transmitted beam. The design angle here was determined by glass's index at about 580. I was a bit surprised at how flat in wavelength the transmission in the 's' polarization is, apparently.

Made to accept (up to) 10 standard microscope slides.
