Polarizing filter colorPol Laserline Nd:YAG - polarizer for Neodym:YAG laser Since Nd:YAG lasers with or without frequency doubling or tripling are very common in industrial and laboratory applications, CODIXX offers the colorPol® Laserline Nd:YAG BC4 as versatile optics for all of the 3 wavelengths 1064 nm, 532 nm and 355 nm. This polarizer provides an extinction ratio of above 10,000:1 (40 dB) at all 3 wavelengths 1064 nm, 532 nm and 355 nm. The polarization for 532 nm is on par with 1064 nm, while the polarization of 355 nm is exactly perpendicular. Sizes available up to 100x60 mm2. Polarizers can be handled like simple glass plates. The polarizer offers a wide acceptance angle. High laser damage threshold of 10 W/cm² for continuous block.
