Etalon​​​​​​​

An etalon is an optical interferometer in which a beam of light undergoes multiple reflections between two reflecting surfaces, and the resulting optical transmission (or reflection) is periodic in wavelength. Etalons can be considered a narrowband wavelength filter and can be used as precise wavelength references in telecommunication applications where the periodicity of the signal provides an array of reference frequencies for the telecommunication frequency grid. When used with active feedback electronics, etalons form the basis of wavelength locking systems that can be used to stabilize the wavelength of a laser.

Etalons are widely used in telecommunications, lasers, and spectroscopy to control and measure the wavelengths of light.

CRYLIGHT is dedicated to manufacturing high precision beamsplitter cubes. The typical etalon types we offer are air-spaced and solid etalons are made from either optical glass or silicon material.
