Optical micro-tips for near-field scanning optical microscopy (SNOM / NSOM)
LovaLite offers a range of optical micro-tips designed for near-field scanning optical microscopy. 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.
For your applications, 3 fibre optics are available from stock and others are available on request.
Our tips can now be provided mounted on tuning fork!
Contact us for more information!
