Product Description
Brief Introcuction of Longpass Filters
Longpass Edge and Dichroic Filters are designed to transmit wavelengths greater than the cut-on wavelength of the filter.
Longpass Edge filter and Dichroic Filters types producted by OPTOLONG 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. Certain Longpass Edge Filters can also be used as cold mirrors to minimize the heat buildup often caused by infrared radiation.
