  • Cost Effective



The OI Series Optical Fiber to Free Space Isolator/Collimator is a passive device that guides lights near 1060 nm in the normal direction while minimizing back reflection and back scattering in the reverse direction for any state of polarization. At the same time, it collimates the output beam to a desired beam size. With Photonwares’s proprietary magnetic-optics technology and proven advanced micro optics design, it features low insertion loss, high isolation, compact structure, high power handling, and high stability. The excellent characteristics of this product make it an ideal choice for application in fiber laser. We currently offer a full range of polarization independent, polarization maintain, and multimode versions. Photonwares also provides customized design to meet special applications.
