Shortpass Filter

Shortpass Edge Filters are used to transmit wavelengths shorter than the cut-off wavelength of the filter. Shortpass Edge Filters are commonly use in life science applications including fluorescence microscopy or for integration into a variety of instrumentation. Shortpass Edge Filters can be used with Longpass Edge Filters to create custom bandpass filters to selectively transmit portions of the spectrum while rejecting all other wavelengths. These optical filters can also be used as hot mirrors to minimize unwanted heat caused by infrared radiation.

JGI offers a variety of Shortpass Edge Filters for performance in the ultraviolet, visible, or infrared.  High Performance OD 4 Shortpass Filters offer superior blocking with maximized transmission. 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 our most popular Shortpass Edge Filters.

Our Long-wave pass& Short-wave pass filters have a steep transition between the region of transmission and reflection, with the out-of-band deep blocking to X-ray or 1200nm, and typical transmission > 90% for passband.
