VIS 635nm CWL Bandpass Filters 

A bandpass filter is an optical element that allows specific wavelength of light to pass through while allowing other wavelength to reflect (or attenuate). According to the working wavelength, it can be divided into: UV bandpass filter, VIS bandpass filter, IR bandpass filter. Bandpass filters are mainly used in anti-counterfeiting recognition, fluorescence microscopes, lidar modules, night vision devices, industrial cameras, laser ranging, barcode scanning, face recognition, fingerprint recognition, medical equipment etc. Specification : Diameter or Size : 5mm ~ 200mm Center Wavelength (CWL): 635nm Peak Transmittance : >90% Cut-off Wavelength : 200-1100nm (customized) Type : Banpadd Filter Realpoo Optics is a professional manufacturer of optical glass lenses, such as Spherical Lens, Glass Rod, Fresnel Lens, Diffraction Grating etc. The optics can be offered with coating or without coating.
