Product Detail
AFR’s 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 500 W average laser power and at competitive cost. It also can integrated with AFR’s patented SteadiBeam™ and SeasonBeam™ technologies to achieve thermal lensing-free beam quality and temperature insensitive high isolation.
