The PP-UVFS-46.0-8.0-TFP68-AR681 from OPTOMAN is a Thin-Film Polarizer that operates at a wavelength of 515 nm and 1030 nm. It has a diameter of 46 mm and thickness of 8 mm. This UV-grade fused silica (UVFS) polarizer has a clear aperture above 41.4 mm, coated aperture of 44 mm, and surface quality of 20-10 scratch-dig (per clear aperture). It has a surface flatness of up to lambda/8 (per any 10 mm area) & lambda/4 (per clear aperture) and parallelism of less than 30 arcsec.
The PP-UVFS-46.0-8.0-TFP68-AR681 has an ion beam sputtering coating with an angle of incidence of 44 deg - 46 deg. It has a reflective surface with high reflectance above 97% (for s-polarized light) & high transmittance of over 90% (for p-polarized light) and an anti-reflective surface with a reflectance of less than 0.1% (for p-polarized light). This polarizer has a protective chamfer of 0.1 mm - 0.4 mm x 45 degrees and chip size of less than 0.1 mm. It is ideal for use in Yb:YAG lasers.
