Dichroic shortpass filters

Edmund Optics has introduced a range of dichroic shortpass filters under its Techspec brand. These versatile filters feature a sharp cut-off wavelength and broad transmission and reflection ranges, and are designed for a 45° angle of incidence. Light rejected by the filter is reflected at 90°, making the dichroic shortpass filters well suited to use in fluorescence applications as well as excellent for use as spectral beamsplitters. The filters feature low polarisation dependence, offer broad spectral ranges, and are made with a precision fused silica substrate.

The filters are available in four common sizes for ease of integration into a wide variety of applications: 400-900nm models are available with diameters of 12.5mm, and 400-800nm models are available with rectangular dimensions of 12.5 x 17.6mm.
