245-W Laser Protective Filter
OD Specifications (Optical Density):
OD 2+ @ 630-650 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.

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.
