Alpha-BBO Glan Laser Polarizer -- Z-GLP005
from Ross Optical Industries

This polarizer is a variation of the Glan-Taylor polarizer with a steep angle for the cut in the prism, which reduces reflection loss at the expense of decreased field of view. It is specially designed and manufactured for high energy application such as laser system. The optical materials exhibit... [See More]

Achromatic Waveplates - Air Spaced
from Tower Optical Corporation

Tower ’s achromatic waveplate (AWP) is similar to a zero-order waveplate, which is made from two pieces of crystal quartz except that the AWP is composed of one piece of crystal quartz and one piece of magnesium fluoride, MgF2. Both of these materials are birefringent, however, by proper... [See More]
