Features

140 Laser Protective Filter

OD Specifications (Optical Density):
OD 4+ @ 2780 nm
OD 4+ @ 2940 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 glasses.
VLT (Visible Light Transmission):
90%
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 glasses may affect the ability to see warning lights/signs or distinguis between colors.
