Description

500W Fiber to Free-space Isolator 

 FT High Power Fiber to Free Space Isolator (HPFSI) is the best choice for high power industrial pulse fiber lasers.

 A newly designed isolator can handle 500W average laser power and at competitive cost. It also can integrated with 

patented SteadiBeam  and SeasonBeam technologies to achieve thermal lensing-free beam quality and temperature

insensitive high isolation.
