WebThere are many different types of optical filters, based on different physical principles: Absorption Filters Absorbing glass filters, dye filters, and color filters are based on intrinsic or extrinsic wavelength-dependent … In general, a given optical filter transmits a certain percentage of the incoming light as the wavelength changes. This is measured by a spectrophotometer. As a linear material, the absorption for each wavelength is independent of the presence of other wavelengths. A very few materials are non-linear, and the transmittance depends on the intensity and the combination of wavelengths of the incident light. Transparent fluorescent materials can work as an optical filter, …
