Product Description Product DetailsLongpass Filters, also known as Longpass Edge Filters, are designed to transmit wavelengths greater than the cut-on wavelength of the filter. Longpass 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 Filters can be used with Shortpass 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.General specificationsProduct namelongpass filterCut-on325-1300nmBlocking wavelength200-1650Optical density:OD3; OD4; OD5; OD6Diameter&Tolerance0.5-600±0.02mmClear Aperture≥90%Thickness&Tolerance0.3-50±0.02mmSurface flatness1/10LambdaSurface quality10-5Beveling45°×0.2mmCoating Hard Coated
