Precision optical filters

... NIR cutoff filters can be found just about everywhere we look in our modern lives. They are equipped to image sensors so that natural colors are produced, and they make digital cameras respond to light ...

... 1. Fluorescence Filters We supply excitation and emission filters offering excellent levels of transmission within a wide range of bandwidths - from one to one hundred nanometers and blocking ...

Precision Spatial Filter is designed to filter the beam from any power, generated by visible to near infrared laser. The result – output beam is delivered with a smooth, near ideal intensity ...

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: ...
