Our Wavelength Meter is a self-contained instrument that measures the wavelength of radiation produced by lasers or other pulsed or cw sources of monochromatic light. The instrument is based on a Fizeau or “optical wedge” interferometer. The fringe pattern produced by the interferometer is digitized and stored in a small computer which converts the fringe pattern into the wavelength (in the desired units) of the interfering light.
