제품 특징

EOT's PAVOS line of Faraday devices builds on over 30 years of experience in succesfully protecting lasers from destabilizing and potentially damaging back reflections. The PAVOS line has been specifically designed to meet the needs of high power and high energy 1 µm (1010 nm to 1080 nm) lasers. 

Our PAVOS rotators and isolators deliver industry-best laser reliability and performance while providing superior isolation and maintaining very high transmission. 

EOT's PAVOS products rely on the Faraday effect from high Verdet constant, low absorption materials to rotate the plane of linearly polarized light in the forward direction and an additional 45° of non-reciprocal rotation in the reverse direction. The PAVOS is available as a rotator or an isolator.

Product specifications are subject to change. All products are RoHS compliant.
Escape ports should be used if rejected light is >1 W or 0.15 J/cmat 10 ns or forward light is >25 W. All stray beams should be properly terminated.
