610nm Narrow Band Filter
Application fields of 610nm narrow band filter: fluorescence analyzer, enzyme marker, cable TV upgrade equipment, wireless transmission equipment, mobile phone bar code scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical instrument, infrared ink recognition, red film recognition and face recognition sensor system. Hand held infrared laser rangefinder, laser rangefinder, optical instruments, medical and health equipment and testing instruments.
The main function of narrow band pass filter is to pass the light of specific wavelength, Optical elements that allow the reflection (or attenuation) of light of other wavelengths. The half wave width is usually controlled at 2onm or less, which can be used in ultraviolet, visible, near-infrared and far-infrared wavelengths. Our narrow-band filter is made of multi-layer hard film by ion assisted deposition of nano materials and high vacuum evaporation, with good film compactness and high imaging definition.
