FemtorFiber ultra 920

Key words:


  • Brighter images with Clean-Pulse technology
  • Fully turn-key with integrated AOM and GDD
  • No noise-stress for animals thanks to fan-free passive cooling
  • Compact laser design saving valuable table space
  • Low cost of ownership using robust & reliable fiber-laser technology

In two-photon microscopy, peak-power is brightness! If you care for the best image brightness, you need short pulses, high power, and most importantly a clean temporal pulse shape.
With TOPTICAs unique Clean-Pulse Technology, the FemtoFiber ultra 920 enables unmatched brightness in two-photon microscopy without unwanted heating of the sample.

Additionally, software-controlled dispersion precompensation (GDD) and an integrated AOM for power modulation, make the system extremely user-friendly.
TOPTICAs robust & reliable fiber laser technology significantly reduces the cost of ownership of your laser systems. In addition, our quiet & compact laser design minimizes noise-stress to the animals while at the same time saving valuable table space.

The FemtoFiber ultra 920 is ideally suited for the two-photon excitation of common fluorophores like GFP, eGFP, Eosin, GCaMP, CFP, Calcein or Venus.
