Product Description

Longpass Filter

Longpass Edge and Dichroic Filters are designed to transmit wavelengths greater than the cut-on wavelength of the filter. Longpass Edge and Dichroic Filters are commonly used to isolate portions of the spectrum in a variety of industrial or life sciences applications including microscopy or fluorescence instrumentation. Longpass Filters are typically designed for a 0° Angle of Incidence, whereas Longpass Dichroic Filters are designed for use at a 45° Angle of Incidence. Longpass Edge and Dichroic Filters can be used with Shortpass Edge and Dichroic 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.
