500W Fiber to Free Space Optical Isolator

Produts Details

Product Name: 500W Fiber to Free Space Optical Isolator 


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

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

patented SteadiBeamTM and SeasonBeamTM technologies to achieve thermal lensing-free beam quality and temperature

insensitive high isolation.
