LP470nm filter
Long pass filterProduct Features
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.
