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.
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 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 below5x10^-5 is claimed. Calcite can be used in the visible to infrared range.
These are prisms for splitting the incident beam into two linearly polarized beams with orthogonal polarization direction. Calcite can be used in the visible to the infrared range.
The polarizer separates the incident light into two linearly polarized light beams that cross perpendicularly.
The polarizer separates the incident light into two linearly polarized lights that cross perpendicularly.
By using a dichroic dye sheet, good linear polarization can be achieved over a wide range.

The beam analysis camera WinCamD-IR-BB with integrated microbolometer array enables analyzes on long-wave lasers in the range of 2 μm to 16 μm.
This Laser Beam Profiler from DataRay is equipped with a CQD sensor and offers a spectral response in the SWIR range of 400 - 1700 nm with resolutions up to 1920 x 1080 pixel.
DataRay's ILM system is used for beam profile monitoring of high power lasers consisting of an attenuator for high powers, an imaging lens system and a camera system. The measurement of very small laser beams with diameters of less than micrometers is possible despite often high laser powers.
A main feature of the WinCamD is the optional M2 Stage. Thus, it can be easily extended to a complete M2 measurement system.
