A dichroic filter is thin optical filter crafted to transmit light in only one narrowly defined wavelength band, while reflecting all other wavelengths. Description. Dichroic filters or bandpass filters are made of polished optical glass that is coated with multiple layers of dielectric thin films that transmit specific wavelengths of light while reflecting undesired wavelengths at a particular angle of incidence. High-performance optical filters are produced by depositing multilayered thin-film coatings on the surface(s) of plane, parallel glass. A complete set of these dichroic filters is available in a Pre-Loaded filter wheel. Choose filters by either "Type" or "Application". Dichroic filters are typically placed at a 45 degree angle to a light source. LD201 Dichroic Full C.T. This dichroic coating has chains of molecules lined up in one direction.

Dichroic filters consist of thin film dielectric coatings on glass and exhibit sharp transitions between transmitted and reflected wavelengths. Dichroic Longpass Filters feature bands of very-low reflectance to create the transmission bands of the filters, and bands of very-high reflectance to create the blocking region of the filters. These filters allow only a portion of the visible spectrum to pass and reject (reflect) the rest. DIF-50S-GRE. Dichroic filters are similar to traditional interference filters but differentiate themselves by reflecting all unwanted wavelengths. Visible Range Dichroic Filter 50mm 495/605nm. Dichroic Filters have a longer longevity than standard filters and as the light is reflected and not absorbed, there is less heating so are widely used in laser and imaging applications. A dichroic filter reflects light of short wavelengths and transmits light of higher wavelengths.
