2021 Latest Design Tgg Crystal - Achromatic Depolarizers – Dien

These achromatic depolarizers consist of two crystal quartz wedges, one of which is twice as thick as the other, that are separated by a thin metal ring. The assembly is held together by epoxy that has been applied only to the outside edge (i.e., the clear aperture is free from epoxy), which results in an optic with a high damage threshold. These depolarizers are available uncoated for use in the 190 – 2500 nm range or with one of three antireflection coatings deposited on all four surfaces (i.e., both sides of the two crystal quartz wedges). Choose from AR coatings for the 350 – 700 nm (-A coating), 650 – 1050 nm (-B coating), or 1050 – 1700 nm (-C coating) range.
