Athermal Wavelength Reference Filter

Primanex's Athermal Reference Filters are based on advanced etalon technology. With Primanex unique opto-mechanical design and advanced packaging techniques, the filters demonstrate extreme wavelength stability under varied environmental conditions including temperature and humidity.

Built by a proprietary precision tuning technique, the filters come with an option of ITU targeting accuracy within +/- 1.25GHz. This ITU-targeted filter can be used in WDM system channel monitoring and wavelength locking. A special option is also available for customer to select specific wavelengths for precision targeting.

The filters come in a transmission form, and come with a broad design options including etalon finesse, channel spacing FSR) and operating wavelength range. The customer friendly product design enables the Athermal Reference Filters to be utilized in a spectrum of diverse applications including telecommunication, wavelength referencing and calibrating in fiber-optics sensing system, test & measurement instrumentation, and laser wavelength stabilization.
