Interference Microscope |
 |
|
An interference microscope (made by aus Jena) is
used to measure the precise optical properties of materials (e.g.
birefringence) and study minute variations in surface morphology.
The interference microscope is based on a Michelson interferometer,
which splits a monochromatic beam of light (a single wavelength of
light from the visible spectrum) into two beams, a beam that passes
through the sample and reference beam. As the sample beam passes
through the sample, it is slowed down relative to the reference
beam. After the sample, the light waves in the two beams recombine;
but in recombination, the waves interfere, either constructively or
destructively, creating light regions in former case or dark regions
in the latter. From the resulting bands of light and dark that make
up an interferogram, we can quantitatively study optical properties
and surface characteristics. |
