Fabry-Perot Etalons

Fabry-Perot etalons serve as optical filters in a wide range of applications where their unique combination of high resolution and transmission is an important attribute. TecOptics Corp.’s precision etalons are vital components for diagnosis and control in a wide range of optical systems, including:

Leading-edge scientific research
Spectroscopy
Industrial instrumentation
Air-spaced etalons for narrow bandwidth astronomy filters
Remote sensing
Scientific and industrial lasers operating in the UV, visible and near-infrared spectral regions, where they supply wavelengths, tuning, and analysis
Narrowband, deep UV lasers for microlithography, where they facilitate wavelength selection and bandwidth control
Wavelength reference etalons for telecommunications
