420 Laser Protective Filter
Window Material:
Acrylic
OD Specifications (Optical Density):
OD 5+ @ 190-375 nm
OD 4+ @ 900-1070 nm
OD 5+ @ 1064 nm
OD 5+ @ 10,600 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):
70.9%
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.
View Through Laser Window Filter*:
*View Threw Laser Window Filter is a general representation of the visibility through the laser window. The color and transmitted light may vary from what is shown. Please contact us for more information about this laser filter and appropriate viewing conditions was well as wavelengths that may not be visible because of these laser window.
