Longpass Edge Filters are designed to transmit wavelengths greater than the cut-on wavelength of the filter. Longpass Edge Filters are used to isolate portions of the spectrum in a variety of industrial or life sciences applications including microscopy or fluorescence instrumentation. Longpass Edge Filters can be used with Shortpass Edge Filters to create custom bandpass filters. Certain Longpass Edge Filters can also be used as cold mirrors to minimize the heat buildup often caused by infrared radiation.
