Lenses of <2 micron Focal Spots

Nanonics produces excellent lensed fiber products through its capability to characterize the structure and the light distribution with near-field optics.

 The Fiber Micro Lens Numerical Aperture

 fiber_microlens_na_775_01

Given the radius of curvature from the AFM topography and the focal distance and size of the aperture of the micro lens and the diameter of the light distribution in the focal plane gives a N.A. of 0.26.

Nanonics systems today provide the best profiling of fiber lasers and ultrasmall lensed fibers in the near and far-fields.
