How discount dispersing prism works
LEARN MORE
+
Discount dispersing prism is a glass block in shape of pentahedron with three optically active surfaces. These prisms operate in transmitted light and are commonly used to diverge light in broad range of optical systems. The direction of light exiting the prism depends on wavelength, a feature which allows the prism to separate incident beam into its component wavelengths.
