Interferometry Lasers Overview

Interferometry is one of the most versatile optical test and measurement techniques because it allows for sub-wavelength resolution.  In an interferometer, a highly coherent laser source is split into two different optical paths, where one path interacts with the object under test.  Then the two resultant interferometry lasers are recombined on a detector resulting in either spatial or temporal variation in intensity.  These intensity variations are known as fringes, and the spacing between two minima or maxima represents an optical path length difference of one wavelength.  Additionally, it’s important to note that the difference in contrast between the bright and dark portions of the fringe pattern is dependent on the coherence length of the laser.  Therefore, to get the highest contrast ratio from the interferometer, single mode single frequency laser sources are required.  On this page, you will find a list of all of the interferometry lasers we offer ranging in wavelengths from 405 nm to 2.1 microns.
