Grism: History & Overview

A grism (also called a grating prism) is a combination of a prism and grating arranged so that light at a chosen central wavelength passes straight through. The advantage of this arrangement is that one and the same camera can be used for both imaging (without the grism) and spectroscopy (with the grism) without having to be moved. Grisms are inserted…
