Interference filter - Wikipedia

An interference filter or dichroic filter is an optical filter that reflects one or more spectral bands or lines and transmits others, while maintaining a nearly zero coefficient of absorption for all wavelengths of interest. An interference filter may be high-pass, low-pass, bandpass, or band-rejection. An interference filter consists of multiple thin layers of dielectricmaterial having different refractive indices. There also may be metallic layers. In its broadest meaning, interference filters comprise also etalons th…

Optical filter - Wikipedia

An optical filter is a device that selectively transmits light of different wavelengths, usually implemented as a glass plane or plastic device in the optical path, which are either dyed in the bulk or have interference coatings. The optical properties of filters are completely described by their frequency response, which specifies how the magnitude and phase of each frequency component of an incoming signal is modified by the filter.

What are the Optical Bandpass Filter Fundamentals ...

When an optical bandpass filter is used with non-collimated light such as convergent or divergent rays, the wavelength shift will appear somewhat less than that of collimated light at the same angle. In a cone of light only the central ray is normal to the surface and all others are increasingly off-angle.

Angle of Incidence (AOI) and Polarization - Optical Filter ...

As an optical interference filter is tilted away from normal, the transmission spectrum is “blue shifted,” which means the spectral features shift to shorter wavelengths (Figure 3). This angle shift becomes more pronounced with increasing AOI and can be calculated in collimated light and for relatively small angles of incidence using the following formula:
