Fast, accurate and extremely portable, it is no surprise the XL-80 system is the best selling calibration laser. You will use the Michelson interferometer to observe the interference of two light sources: a HeNe laser and a sodium lamp. In one method, a frequency difference is introduced between the two beams in the interferometer, usually by means of a pair of acousto-optic modulators operated at slightly different frequencies. That gives you circular fringes that flow inwards or outwards as you adjust the path length. An interferometer is a scientific instrument used to measure wavelengths of waves (usually light waves), distances, and shapes of surfaces to a high level of accuracy.
