Description

440 is an Acrylic laser safety window offering protection primarily from Alexandrite (755 nm), Diode lasers (980 nm), Nd:YAG lasers (1064 nm), UV lasers (190-375 nm), and CO2 lasers (10,600 nm). Laser windows can be custom cut, molded, and drilled to your CAD specifications for use in enclosures or machine windows. This laser safety window may provide protection from other laser wavelengths not listed. Please see Product Information for additional information about this filter or contact us. Filter specifications can be permanently engraved on the window. Custom sizes and shapes available.This laser safety viewing window meets and/or exceed US ANSI Z136 standards for use with lasers.

440 Laser Protective Filter

Window Material:

Acrylic

OD Specifications (Optical Density):

OD 5+ @ 190-399 nm
OD 2+ @ 400-480 nm
OD 2+ @ 750-1900 nm
OD 3+ @ 800-1800 nm
OD 5+ @ 830-1700 nm
OD 6+ @ 1064 nm
OD 5+ @ 10,000-11,000 nm

Optical Density: is a measure of the transmittance of an optical element for a given length at a given wavelength. 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):

25%

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.
