Request InfoEdmund Optics Inc.The newly expanded line of antireflection (AR) coatings from Edmund Optics is now available in standard models for faster turnaround. The series includes the YAG-BBAR coating, which is a broadband coating from 500 to 1100 nm, and optimized for low reflection at both 532 and 1064 nm. It provides less than 1 percent reflectance per surface over its wavelength range and absolute reflectance of less than 0.25 percent where it is optimized. The AR coatings series also includes the VIS-EXT BBAR, which offers extended UV performance, and provides less than 0.5 percent average reflectance...See full productRelated content from Photonics MediaPRODUCTSPromoted Content February 2022 IssueWGF Infrared (IR) Polarizing Camera FilterWGFTM IR polarizing camera filter is made with WGFTM, the world's first film-based wire grid polarizer.
