Quartz depolarizers convert linearly polarized input beams into unpolarized beams and are used in front and behind of measurement equipment that must avoid polarization.

◦1N type is made of single optical quartz plate. It has a wider transmission range, but has a larger beam deviation due to the 2 degree wedge shape.
◦2S type consists of cemented plates of optical quartz and synthetic fused silica. It does not have beam deviation, but the transmission range is not as wide as the single type.
◦OP type consists of optical contact. It has a wider transmission range without beam deviation.
◦It is similar to waveplate and mounted in a frame of ø30mm diameter.
