Product DescriptionProduct DescriptionA dichroic filter is a precision optical component designed based on the principle of light interference, distinguished by its ability to selectively transmit one wavelength range and reflect another, enabling wavelength separation or combination. It is typically fabricated by depositing multilayer dielectric films (e.g., metal-dielectric or all-dielectric coatings) on an optical glass or quartz substrate, achieving interference effects at specific angles of incidence through precise design of film thickness and refractive index. Its core performance is determined by the cutoff wavelength, bandwidth, and spectral reflectance/transmittance: the cutoff wavelength defines the boundary between transmission and reflection, the bandwidth reflects the sharpness of wavelength selection (narrower bandwidth means higher color separation accuracy), and the reflectance/transmittance directly affects light signal separation efficiency. Unlike ordinary band-pass filters, dichroic filters are more sensitive to the angle of incidence and polarization state, requiring strict control of optical path angles in applications. They can be designed as short-pass or long-pass dichroics, widely used in fluorescence microscopy, projection systems, stage lighting, laser beam combining/splitting, biomedical detection, and other fields.SpecificationProduct Name Dichroic FilterDiameterCustom MadeThickness±0.02mmDimension Tolerance±0.02mmSurface Quality60/40, 40/20 ,20/10 or betterSubstrateColored GlassCoatingCustomTypeAndpass FilterOptical Applications?Uses light interference to selectively transmit one wavelength range and reflect another, enabling wavelength separation or combination.Typically composed of optical glass or quartz substrate with multilayer dielectric coatings (e.g., metal-dielectric or all-dielectric films).Interference-type: Achieves wavelength selectivity through multilayer thin-film interference (nearly all dichroic filters are interference-based).Company ProfileTianjin Fushi Optics Co., Ltd.Tianjin Fushi Optics Co., Ltd. is a comprehensive optoelectronic enterprise integrating R&D, production, sales, and after-sales service.
