Description
Polarizing film takes regular randomized polarizing light and lets only light with one polarizing orientation through. If you take two pieces of polarizing film and place them at 90° to each other they will block out all light. Polarization is used in microscopy, stress testing, light control, and hundreds of other purposes.
2 Pieces of 6" Square Polarizing Film.
