Prism definition, Optics. a transparent solid body, often having triangular bases,
used for dispersing light into a spectrum or for reflecting rays of light. See more.

an image and make use of total internal reflection instead of refraction.
Jan 1, 1997 ... Spherical, or parabolic, mirrors are often used in optical systems .... Prisms are
also used to redirect light by refraction or internal reflection.
Prisms of this kind are used in certain spectroscopes, instruments for analyzing
light and for determining the identity and structure of materials that emit or absorb
right-angle prisms to be used to bend light by 90° or 180°. Some prisms like the ...
