Description
245 Glass laser safety window filter was primarily developed for protection from multiple lasers wavelengths: Nd:YAG, Helium-Neon, Krypton, Chromium:Sapphire, and Ruby lasers. This laser protective window may provide protection from other laser wavelengths not listed. Please see specifications for additional information about the laser protective filter, or contact us. Filter specifications are permanently engraved. These laser safety window meet and/or exceed US ANSI Z136 standards for use with lasers.
These laser safety glasses meet and/or exceed US ANSI Z136 standards for use with the appropriate laser systems.
245-W Laser Protective Filter
OD Specifications (Optical Density):
OD 2+ @ 630-650 nm
OD 3+ @ 650-690 nm
OD 6+ @ 690-1330 nm
OD 3+ @ 650-690 nm
OD 6+ @ 690-1330 nm
Optical Density: is a measure of the transmittance of an optical element for a given length at a given wavelength λ. The higher the optical density, the lower the transmittance of light at a specified waveleng. See the ANSI Z136 for more information about OD and laser windows.
VLT (Visible Light Transmission):
50%
VLT: The attenuation of light by a filter in the visible spectrum. VLT is determined in relation to standard illumination and evaluated according to the daylight-adapted (photopic) or night-adapted (scotopic) conditions descriped more in the ANSI Z136.7 for Testing and Labeling of Laser Protective Equipment. The lower the VLT, the less "visible" light is transmitted. Laser windows may affect the ability to see warning lights/signs or distinguis between colors.
Compatible Laser Systems and Wavelengths:
WARNING: THESE LISTED LASER SYSTEMS ARE COMPATIBLE BY WAVELENGTH ONLY. ALWAYS VERIFY YOUR LASER'S WAVELENGTH AND OPTICAL DENSITY REQUIREMENTS BEFORE PURCHASING LASER GLASSES.

LSOs (Laser Safety Officer) need to consider working environments, viewing conditions and beam delivery systems when making assessments and determining the correct laser glasses , goggles, barriers, or windows to protect against potentially hazardous laser radiation. Do not operate lasers without correct protective equipment and training.
