• Biconical Optical Lensed Fiber
  • Photonstream offers unique lensed and tapered lensed fiber for optical coupling like waveguides, optical fibers, and diode lasers. Our biconical 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.
