Etalons

An etalon is a two flat glass plate separated by a parallel spacer, with the inner surfaces of the plates coated with a partially reflecting layer. When the etalon is placed in a beam of monochromatic light, multiple interference occurs, forming circular fringes in the manner of the Fabry-Perot interferometer.

Glossary
  • etalon Two flat glass plates separated by a parallel spacer, with the inner surfaces of the plates coated with a partially reflecting layer. When the etalon is placed in a beam of monochromatic light, multiple interference occurs, forming circular fringes...
  • etaloning A phenomenon that degrades the performance of thinned, back-illuminated CCDs. The effect is caused by lightwaves passing through the CCD and reflected at the rear surface, producing interference fringes when they interact with incoming waves.
  • Fabry-Perot etalon A nonabsorbing, multireflecting device, similar in design to the Fabry-Perot interferometer, that serves as a multilayer, narrow-bandpass filter.
