Sp900nm filter
Short wave pass filter Features
Short-wave pass as the name suggests is a short-wave direction of the light through the long-wave direction of the cut-off filter, short wave pass filter produced by our company has a large cut-off, high transmittance and background light density advantages , And completely different from the traditional optical glass method, when the incident angle changes (from 0 degrees to a large angle rotation), the characteristic cutoff wavelength will shift to the shortwave direction. This feature can be used in the fine-tuning system, and can get your desired wavelength .
