MICHELSON INTERFEROMETER Description and Specifications for Lab Tenders
MICHELSON INTERFEROMETER.
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.
