MICHELSON INTERFEROMETER

Model HV-EXP2426
MICHELSON INTERFEROMETER Interferometer is a basic instrument used to measure wavelengths, index of refraction and temporal coherence of optical rays, in an accurate way. Michelson interferometer uses the interference phenomenon to measure the wavelength of light of a particular monochromatic source. The instrument described in this catalogue outputs interference fringes by splitting a ray into two beams. Each beam is forced to cover a different path, then they will rejoin so that they can interfere according to the difference in path length. This enables a precise measurement of the wavelength of monochromatic light. When a ray of coherent light enters the ray splitter, it is split into two beams, then these two beams travel in different directions and they are reflected to each other through two mirrors that create interference figures after they have been combined and superimposed.
