The PL1-FN7-C-A-100-SA is an Athermal Fabry-Perot Interferometer Etalon consisting of an advanced opto-mechanical design hermetically packaged to yield premium wavelength stability. Used as wavelength reference in the calibration of Optical Spectrum Analyzers, Tunable Lasers, Tunable Filters, Chemical Analysis Systems, and Optical Sensing Systems. Code share with TWR30 Etalons.

The PL1-FN7-C-A-100-SA-14BF Etalon is terminated with single-mode (SM) fiber for easily interfacing to optical instruments or to other optical components. The precision athermal packaging yields excellent wavelength stability despite changes in temperature or humidity. Standardized at 25GHz channel spacing, but also available at 50GHz, 100GHz, and 200Ghz. Designed to make handling and installation fast, easy and intuitive. It delivers the many advantages inherent to all optical devices.

Widely used in optical test and monitoring instruments, the PL1-FN7-C-A-100-SA-14BF is well fit for telecom systems, for medical and pharmaceutical applications, and for optical sensing applications in security, robotics, civil & geotechnical engineering, oil & gas, aerospace, railways, roadways, performance gear, marine vessels & racing yachts, wind turbines and structures, pipelines, nuclear facilities, industrial processes, and for research laboratories worldwide.
