Optical Thin Film Filtel IR Filter High Pass Filter Thickness 0.5-1.0mm
Characteristics
Compared with traditional colored optical glass filters, our product have large cut-off steepness, high transmittance and high background optical density. When the incident angle changes (from 0 degrees to a large angle), the characteristic cut off wavelength will move to the short wave direction which is completely different from the traditional optical glass.
