Etalons are suitable for telecommunications and laser applications
Optical Surfaces
Fabry-Perot etalons
Optical Surfaces is offering Fabry-Perot etalons, which are used for measuring the wavelengths of light in telecommunications, lasers and spectroscopic applications.
The etalons are available in a range of sizes of up to 150mm in diameter with matching accuracies to λ/300.
They are available in air-spaced and solid forms and are designed for use a wavelengths between 190nm to about 2microns.
Those with smaller diameters are supplied with wedge angles of 5 min of arc, which rises in steps to a wedge angle of 40 min of arc for units with a diameter of greater than 70mm.
