UV Shortpass Filters
Asahi Spectra
產品特色
- High transmission and high rejection for complete isolation
- Sharp cut-off wavelength
- Will not autofluorescence
- Excellent thermal resistance
Our UV shortpass filters are designed to have a very sharp transition between the reflect and pass bands while maintaining very high transmission at UV pass bands.
The spectral transmission properties are uniform over the entire aperture of the filters. UV shortpass filters can be combined with our UV longpass filters in pairs to create a variety of transmission bands.
