An optical filter that reflects one or more optical bands or wavelengths and transmits others, while maintaining a nearly zero coefficient of absorption for all wavelengths of interest. Note: A dichroic filter may be high-pass, low-pass, band-pass, or band rejection.

A material that splits visible light into different wavelengths, allowing for precise control of the spectral band. Dichroic filters are coated on the glass and only allow certain wavelengths or colors to pass through. Dichroic filters are different from colored glass filters, which are used mostly for aesthetic purposes.

It is an optical filter that changes the amount of transmissivity of incident light in response to different wavelength of such light in central and peripheral areas. Since a single pickup supports tw [..]

A type of filter coated with thinfilms to achieve a desired transmission and reflection percentage across a given spectrum. It is often used as a color filter (both additive and subtractive). A dichro [..]
