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
