Etalons Explained
Manx Precision Optics (MPO) produces coated optics, uncoated optics and polarization optics products. Etalons comprise one of the categories of uncoated optics.
Etalons are optical components based on the principle of the Fabry-Perot Interferometer. They are effective narrow band filters, transmitting only light of specific, periodic frequencies with tight bandwidths. They are commonly used in applications such as telecommunications, lasers and spectroscopy.
An Etalon consists of two flat, partially reflecting plates separated by a distance. The gap between them, either in vacuum or filled with air or some solid substrate forms an optical cavity. These two types, known as “Air Spaced” and “Solid” Etalons, respectively, possess different advantages and disadvantages.
