Product Description - In-line Fabry Perot Etalon

Optoplex’s Inline Fabry-Perot Air-Gap Etalon is based on its proprietary free-space optics technology. It provides periodical narrow passbands in both transmission and reflection modes. To ensure stability, the etalons are hermetically sealed and optically aligned to the input and output fiber collimators. Use of athermal optics and advanced manufacturing process allows these Fabry-Perot Etalons to maintain excellent accuracy of better than ±1.5 GHz within 0 ~ 70°C operating temperature range. The Inline F-P Etalons offer superior accuracy in free-spectral-range and great channel center wavelength stability.
