Shortpass Filters with Cut-Off Wavelength (Range) 900 - 1000 nm and Transmission Region Cut-off λ to 455 nm

Short pass filter spectral curveShort Wavepass Filters

A shortpass filter or short wavepass filter (SP filter) is a filter that transmits at shorter wavelengths and rejects longer wavelengths. By design, the transition in a shortpass filter between the 50% cut-off or cut-on to rejection is quite sharp. This makes it much easier to separate excitation from emitted wavelengths without interfering with wavelengths of interest. Short wavepass filters are useful in applications where spectral noise reduction is important or for isolating a particular region of the spectrum.
