Spectral colors and wavelengths
This chart shows colors of the visible light spectrum, and the
associated wavelengths in nanometers. Ranges are traditionally given as: ultraviolet
light, 100-400 nm; visible light, 400-750 nm; and infrared, 750 nm-1 mm.
Major laser wavelengths
This chart shows common types of lasers, and the major wavelengths associated with them.
(Additional charts showing ion lasers' major wavelengths are on
this page.)
Lexel model numbers are given for applicable Gas-Ion and deep UV Gas-Ion Second
Harmonic Generation (SHG) lasers. For more information, click on the Lexel model number
link. Note that additional custom laser wavelengths may be possible;
contact Cambridge Lasers for more information.
