LASER WAVELENGTH CHARTS

 

   

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.
