Examples
-
Swift's Ultraviolet / Optical Telescope includes a device called a grism that can separate wavelengths in ultraviolet light in much the same way as a prism spreads sunlight into colors.

Light would come in from 640 quasars or stars or galaxies, be passed on through 640 optical fibers, sent to a combination of a diffraction grating and a prism—called a grism—which could fan the light out into 640 little spectral rainbows, which would register on the same-sized CCDs as in Jim’s camera.
