425nm langwave pass filter
Compared with the traditional colored optical glass filters, the short wave pass and long wave pass filters produced by our company have the advantages of large cut-off steepness, high transmittance and high background light density, and are completely different from the traditional optical glass methods. When the incident angle changes (rotating from 0 ° to a large angle), the characteristic cut-off wavelength will move to the short wave direction. This function can be applied to system fine-tuning and get the wavelength you need.
