Short Pass Filter

short pass filter

Short pass filter description: 

Short pass filter  is a filter in which the pass band is a wavelength range lower than the wavelength range that is blocked. It  pass all wavelengths shorter than the cut off wavelength, and it includes IR cutoff filters, hot mirrors, and heat absorbing filters.

Difference between long pass filter, short pass filter, dichroic filter and IR/UV cut Filter

Long pass Filter can transmit wavelengths greater than the cut-on wavelength, while Short pass Filters transmit wave-lengths shorter than the cut-off wavelength. Dichroic filters perform the same function, while guaranteeing that the  rejected wavelengths are reflected. Any of these filters can be designed for 0  or 45  angle of incidence. Edge and Di-chroic Filters are commonly used in Fluorescence instrumentation, Heat Rejection Applications, and as Color Filters.  While somewhat angle sensitive, they are more forgiving than bandpass interference filters.
