collimator 2

noun

optical device consisting of a tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beam

diffraction grating 1

noun

optical device consisting of a surface with many parallel grooves in it; disperses a beam of light (or other electromagnetic radiation) into its wavelengths to produce its spectrum

prism 2

noun

optical device having a triangular shape and made of glass or quartz; used to deviate a beam or invert an image

spectrophotometer 1

noun

a photometer for comparing two light radiations wavelength by wavelength

Definition

an optical device that transmits a mechanically selectable narrow band of wavelengths of light or other radiation chosen from a wider range of wavelengths available at the input.

Examples

1.A monochromator can use either the phenomenon of optical dispersion in a prism, or that of diffraction using a diffraction grating, to spatially separate the colors of light.
