Dichroic Beam Splitter

Dichroic beamsplitters alluxa optical filters high performance dichroic filters and polychroic filters.

Dichroic beam splitter.

Thorlabs dichroic mirrors beamsplitters consist of a hard ion beam sputtered coating deposited on a uv fused silica substrate providing excellent transparency over the operating wavelength range virtually zero autofluorescence and a low coefficient of thermal expansion making them an ideal choice for applications from the uv to the near ir. Dichroic beamsplitters dichroic filters separate a broad spectrum of light into two components. A reflected component and a transmitted component. Dichroic beamsplitters mirrors are used as light guiding optics intended to reflect a specified range s of wavelengths and transmit a different specified range s of wavelengths at a specified aoi typically 45 degrees.

They highly reflect one specified spectral region while optimally transmitting another. Laser beam combining or splitting optical system heat control and fluorescence microscopy are a few of the most common uses of dichroic filters. Steep edges allow this separation within a few nanometers. Most of chroma s catalog dichroics are intended for use at 45 degrees aoi if unsure please ask us.

Dichroic beamsplitters are longpass and shortpass filters that are used at non normal angles of incidence. The beam splitters are free of absorption and guarantee highest values in transmission and reflection.
