Shortpass Filters, also known as Shortpass Edge Filters, are used to transmit wavelengths shorter than the cut-off wavelength of the filter. Shortpass Filters are commonly use in life science applications including fluorescence microscopy or for integration into a variety of instrumentation. Shortpass Filters are typically designed for a 0° Angle of Incidence, whereas Shortpass Dichroic Filters are designed for use at a 45° Angle of Incidence. Shortpass Filters can be used with Longpass Filters to create custom bandpass filters to selectively transmit portions of the spectrum while rejecting all other wavelengths. Shortpass Edge Filters can also be used as hot mirrors to minimize unwanted heat caused by infrared radiation. The phrase "High-Pass Filter" is commonly used to refer to frequency instead of wavelength, so "High-Pass Filter" counterintuitively refers to Shortpass Filters, not Longpass Filters. "Lowpass Filter" similarly describes frequency and refers to Longpass Filters.

Edmund Optics offers a variety of Shortpass Filters for performance in the ultraviolet, visible, or infrared. TECHSPEC High Performance OD 4 Shortpass Filters offer superior blocking with maximized transmission. TECHSPEC Dichroic Shortpass Filters feature low polarization dependence, broad spectral ranges, along with hard coatings ideal for use in harsh environments. Shortpass Edge Filter kits are also available containing some of Edmund Optics’ most popular Shortpass Edge Filters.
