Brief introduction of the product：

A band pass filter separation of monochromatic light from the composite light filter. It has a light distribution curve of symmetric, central wavelength transmittance maximum. Peak transmittance at half wavelength spacing, delta lambda two symmetric points on the curve for the light filter bandpass half width (bandpass half-width). Divided into narrow band filters and broadband filter. For the spectral instruments to eliminate overlapping grating spectral order.

Optical index：

The center wavelength: customer needs

The peak transmittance：T>90%

The band width：30~60nm

The cutoff range：400-1100nm

The cut-off depth：T<0.1%

The size of the optical index, can be customized according to customer requirements!

Application field：

The 3D scanner, laser range finder, four wheel positioning device, laser shoot intrusion detector, infrared cameras, mobile phone bar code scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical instrument, infrared printing ink recognition, red film recognition, face recognition system of sensors, instruments etc..
