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.
