Short Pass Filter is Useful for isolating short wavelength regions of the spectrum. Unlike colored filter glass, the cut-on and cut-off wavelength of long pass filters and short pass filters will shift to a shorter wavelength as the angle of incidence is increased. This feature can be useful in applications where it is desirable to fine tune the location of the cut-on, or cut-off wavelength. In addition, our edgepass filters are hermetically sealed to provide maximum humidity protection, and they can be stacked to create a custom bandpass filter.
Shortpass filter transmission region is 0.7 x Cut-off-Wavelength to Cut-off-Wavelength (Unless 0.7 x Cut-off-Wavelength is < 400 nm, then 400 nm to Cut-off-Wavelength).
Shortpass filter rejection region is 1.3 times Cut-off-Wavelength.
