Fabry Perot Etalon OE-7021

Description

 

Etalon is design by transparent plate with two parallel highly reflecting mirrors. An etalon is an optical interferometer in which a beam of light undergoes multiple reflections between two reflecting surfaces and its resulting optical transmission (or reflection) is periodic in wavelength. Etalons transmit light as a series of periodic frequencies and their narrow bandwidth makes them well-suited for wavelength selection, measurement and line-narrowing. In other words, an etalon is a narrow band wavelength filter.

Experiment Performed

  • To find the Spacing of the Etalon
  • To find the Finesse and Free Spectral Range of the Etalon

Feature

  • Precision design of optical components
  • Highly polished etalon
