25.4mm Dia., 6.35mm Thick, 1064nm, Nd:YAG IBS Laser Line Window

Product Details IBS Coated for Minimal Absorption and Scatter <0.1% Reflectivity at Nd:YAG Laser Lines Certified Laser Damage Thresholds at Design Wavelength TECHSPEC IBS Laser Line Windows feature an ion beam sputtering (IBS) anti-reflection coating that provides <0.1% reflectivity at their design wavelength with minimal losses due to absorption or scatter. The IBS coating process produces dense, homogeneous coating layers that are environmentally stable and insensitive to temperature and humidity changes, enabling these windows to be used in harsh environments. TECHSPEC IBS Laser Line Windows are available in standard imperial sizes with designs for the Nd:YAG laser wavelengths of 355nm, 532nm, and 1064nm. In-house manufacturing enables Edmund Optics to provide custom sizes and designs in the wavelength range 343nm to 1600nm.
