Lp780nm filter
Compared with the traditional colored optical glass filters, the short wave pass and long pass filters produced by our company have the advantages of large cut-off, high transmittance and large background optical density, and are completely the same as traditional optical glass methods Different point, when the angle of incidence changes (from 0 degrees to a large angle rotation), the characteristic cut-off wavelength will be to shortwave direction. This feature can be used in the fine-tuning system, and can get your desired wavelength.
