Chromacity 920

A highly-stable 920 nm femtosecond laser to achieve your two-photon microscopy goals.

This exciting new 920 nm femtosecond laser is the next generation of fiber-based technology which is enhancing multiphoton imaging with higher resolution and faster acquisition at significant depth.


The 920 nm femtosecond laser is ideal for multiphoton excitation (MPE), particularly two-photon excitation of fluorophores and calcium markers (including YFP, GFP, eGFP, GCaMP). 


Chromacity’s range of ultrafast lasers are distinctively quick and simple to install, with an intuitive user-interface to guide ease of operation.


Fiber coupling capability reinforces seamless integration into microscopy set-ups for fundamental research and industrial applications, with maximum optical power transmission and minimal dispersion of the femtosecond pulses.


With the advent of the Chromacity 920 to complement our Chromacity 1040 femtosecond laser, these truly-stable fiber-based systems equip researchers to make new discoveries in biomedical imaging.


Chromacity has a decade of experience in the manufacture and configuration of performance characteristics for ultrashort-pulse lasers to support your multiphoton imaging goals.
