Overview
Sigma optical polarizer
Product Details
Product Introduction
Due to its glass material, it is not easily damaged or corroded, and has good durability.
Low absorption and high transmittance in the infrared wavelength range. Therefore, it can also be used for high-energy lasers.
The components are fixed on the frame and can be easily installed on the bracket.
information
▶ There are also large aperture near-infrared polarizing filters (SPFN) available.
▶ When requesting no framework, please inquire at the sales department.
Attention
▶ Due to being an infrared polarizer, most visible light will be absorbed.
▶ When used for wavelengths other than the applicable wavelength, the extinction ratio will deteriorate.
