Laser Spectrum Analyzer SA-800-NIR Plus, 980 nm to 1145 nm mirrors, other wavelengths optional
Highest Finesse Available
The SAPlus Laser Spectrum Analyzer employs a piezoelectrically scanned confocal mirror Fabry-Perot interferometer to provide the finesse necessary to achieve high-resolution measurements. For wavelengths greater than 1000 nm, the SAPlus is the only laser spectrum analyzer of its kind to guarantee a finesse of over 300. At shorter wavelengths, a finesse greater than 200 can be expected. The free spectral range of the SAPlus system is configured for 8 GHz. The system can be reconfigured to a different free spectral range by simply changing the mirror set.

LIKE NEW!  Fabry-Perot RC-140 or RC-110 with Ramp Generator piezo electronics configured with mirrors of choice.  Includes kinematic base.  DAS-10 Stabilization electronics available as option.

We specialize in the rebuilding and repair of Burleigh's Fabry-Perot instruments having sold systems to US government labs and research facilities around the world.  We offer custom fabrication of etalon mirror sets using Burleigh's original vendors and suppliers. These mirrors are produced to a higher specification than original designs using lambda/200 flat substrates.
