The IR-CUT optical filter is made of optical glass or B270 and coated with an optical cutoff coating and or anti-reflective coating. It is allows visible light to pass ...

These filter coatings transmit varying wavelength bands, which are determined by two cutoff wavelengths. Filters can be made at any given wavelength from near ultraviolet to near infrared. Common Specifications Wavelength:448.0nm,514.5nm,526.5nm ...

... just difference to LWP, transmit over shorter wavelength band and reflected over longer wavelength band. Both of LWP and SWP filters are used in communication, displayer and other laser use, such as WDM, IR-Cut and color wheel.

Long Wavelength Pass Coating（LWP）is used generically filters that transmit over longer wavelength band and reflected over shorter wavelength band. Surface Flatness: Lambda/10 Laser Threshold: 300MW/cm2, 1J/cm2 Pulsed FWHM: ...
