This passive device transmits high power light from input fiber into a free space collimated output beam while blocking the unwanted light from back reflection and scattering. Photonwares’s proprietary magnetic-optics technology and advanced end-cap technique enable industrial leading performance in power handling, low loss, reliability, and cost effective. Photonwares currently provides a full range of polarization-independent, polarization maintaining, and custom design versions with a broad wavelength coverage and  various  output beam diameters. We have experience to incorporate special fibers.
