QSWP- Short Wave Pass Filters

A short wave pass filter describes any filter that blocks longer wavelengths and transmits shorter wavelengths. Hot Mirrors and NVIS filters are specialized forms of SWP that separate the visible from the NIR. Quantum offers a full range of SWP filters with pass band, stop band and cut-off wavelengths anywhere from the UV to NIR. SWP filters are often used in conjunction with absorbing glass substrates to create a band pass filter, and transmission in the pass band can be enhanced with an antireflection coating on the second surface.
