660nm long wave pass filter

Compared with the traditional colored optical glass filter, the short wave pass filter and the long wave pass filter produced by our company have the advantages of large cut-off gradient, high transmittance and large background light density, and are completely different from the traditional optical glass method. When the incidence angle changes (turning from 0 degrees to a large angle), the characteristic cut-off wavelength will move to the short wave direction. This function can be applied in system fine-tuning and can obtain the wavelength you need.
