Polarizers
Two-part air-gap waveplates are suitable for use with high energy lasers.
Quartz waveplates are zero-order retardation plates composed of pairs of optically contacted crystalline quartz plates mounted on aluminum frames.
Mica waveplates are zero-order retardation plates designed for a wavelength of 550 nm and effective from 400 - 700 nm.
This optical retardation can be given without the wavelength dependence for all visible regions.
They are special polarizers with minimal transmission loss. α-BBO crystal type, which can be used in the ultraviolet range.
These are special polarizers with minimal transmission loss. Calcite can be used in the visible to infrared range.
Glan laser polarizers are designed to provide increased laser damage threshold for high power lasers and high energy laser pulses. α-BBO crystal type usable in the ultraviolet region.
Glan Laser Polarizers are designed to provide enhanced laser damage threshold for high power lasers and high energy laser pulses. Calcite can be used in the visible to infrared range.
Transmission loss is minimal, and a high extinction ratio of less than5x10^-5 is targeted. α-BBO crystal type usable in the ultraviolet region.
Transmission loss is minimal, and a high extinction ratio below5x10^-5 is claimed. Calcite can be used in the visible to infrared range.
They are prisms for splitting the incident beam into two linearly polarized beams with orthogonal polarization direction. α-BBO crystal type can be used in the ultraviolet range.
