Polarizers take light with a random polarization state and pass light with only one polarization orientation. Two polarizer filters placed at 90° to each other (called "cross polarizers") block light out completely.
Experimental Grade Linear Polarizers are offered in several experimental grade options. Grade 1 is standard optical glass, edged, free of visible scratches, chips, stains or oxidation. Grade 2 is unedged, non-optical glass, small chips, slight stains or other defects.
Note: Specifications for experimental grade optics may vary as much as 10% from those listed. Also, no additional information is available other than what is provided.
