Photonstream offers unique lensed and tapered lensed fiber for optical coupling like waveguides, optical fibers, and diode lasers. Our optical lensed fibers can be integrated with scanning probe microscopes and thus can be used for imaging and nanomanipulation. The lensed fibers are produced by using different fine lens tip shaping techniques and the surface is treated by planar or spherical finishing, optionally the tip was coated with thin film layer. By our process of discharging, etching, lapping, polishing and gringing the end face of the fiber, we could configure the lensed fiber form similar to an actual lens shape suitable for connection and improved coupling efficiency with LD & PD Modules.
