optical parts long pass filter

Compared with traditional colored optical glass filters, our company produces long-wavepass filters with the advantages of large cut-off steepness, high transmittance and high background optical density, and is completely different from the traditional optical glass method. When the incident angle changes (from 0 degrees to large angles), the characteristic cut-off wavelength will shift to the short wavelength direction. This function can be used in system fine-tuning to get the wavelength you need.

Application field
Beauty equipment, police multi-band detection equipment, strong light flashlight, stage lighting color film, face recognition attendance instrument, optical instrument, optical fiber lighting, gold halide lamp heat insulation film, cold light source display cabinet.

Optical index
Transmission band: 660nm-1200nm
Minimum transmittance: T>95%
Center wavelength: 650nm±3
Cut-off band: 400nm-640nm Cut-off depth: T<0.1%
