Micro-Lensed Optical Fibre

Lensed fibre is produced using different fine lens tip shaping techniques.Each micro-lens characterised using:
  • Far optical field and near optical field analysis
  • Return loss
  • Working distance measurements and geometrical measurements
  • Shape of the lens (radius of curvature) - The shape of the lens is controlled in one or both planes to match FWHM of the source - can be set between 3 to 500 um.
Micro-lensed fibre can be characterised at different wavelengths: 405, 677, 860, 980, 1300 -2000 nm. (Far optical field; Optional: Near optical field, working distance scan; back-reflection)
