470 Short Wave Pass (SWP) Filters
470 SWP filters are often used in fluorescence microscopy and other applications where near UV and blue pump wavelengths are required. Our 470 SWP filter passes an average of 85% of energy from 340nm-450nm wavelengths. Average transmittance from 500nm-700nm is reduced to less than 0.5%. Performance is specified at normal incidence. This coating is typically provided on Borofloat® glass but can also be coated onto fused silica or other UV transmissive glass materials.
