OPTICAL MICRO-TIPS

LovaLite offers a range of optical micro-tips and probes designed for near-field scanning optical microscopy (SNOM/NSOM). Two technologies are available:
  • P200 - Polymer optical micro-tips
  • E50 - pulled optical micro-tips
All our tips are individually light leakage proved at 400 µW, 532 nm. Our tips are compatible with any SNOM using a tuning fork and shear force.


Products

We offer 3 standard fibre optics that will cover most applications. Other fibres are available on request.
