An item having two plane-parallel surfaces and used in the telescopic system of an optical instrument to modify the density or spectral intensity of light by absorption. Several filters having varied characteristics are usually mounted in such a manner that any selected filter may be moved in or out of the optical axis as light conditions warrant. Excludes window, optical instrument.
