Lensed Fiber

lensed2

Nanonics offers unique lensed and tapered fiber probes for optimal coupling to and from optical micro and nano devices such as waveguides, optical fibers, and diode lasers.

Nanonics lensed fibers can be integrated with scanning probe microscopes and thus can be used for imaging and nanomanipulation.

The lensed fibers are produced by glass pulling technology and IR laser shaping. Single-mode (SM), Multimode (MM), and Polarization maintaining (PM) lensed fibers for the wide range of wavelengths are available.

 

Key Features 


NEAR-FIELD AND FAR-FIELD OPTICAL CHARACTERIZATION WITH NANOMETRIC ACCURACY

 

Accurate tests of lens profiles can be performed with near-field optical microscopy, providing detailed optical properties of the lens. These tests are performed using simultaneous near-field/far- field optical techniques and AFM topographical imaging. Simultaneous topographic and NSOM measurements on the lensed fiber surface enable to test the centricity of the lensed fiber. NSOM characterization in X, Y and Z direction allows to get the focus spot size and working distance with nanometric resolution.

SUB-MICRON SPOT SIZE

Nanonics offers lensed fibers with spot sub micron spot size for the most effective coupling with optical nanodvices.
