High beam quality and pulse duration
Beam quality and pulse duration is specified to perfectly match your microscope or any other femtosecond experiment. Because of these capabilities, it is possible to image more dyes and fluorescent proteins, and to obtain deeper images faster than with any other laser.
High power
The high power from the Chameleon Ultra II makes it an ideal pump source for the Chameleon Compact OPO wavelength extension, enabling imaging even further into the infrared
Ultrawide tuning range
The Chameleon Ultra II’s 680 nm to 1080 nm tuning range allows peak excitation of any marker – from short-wavelength dyes such as Indo or Fura, ubiquitous fluorescent probes such as eGFP, and also red shifted probes such as the mFruits and RCaMP. High peak power at the sample also ensure optimum native fluorescence excitation or SHG imaging.
Versatile
Chameleon Ultra is the true workhorse of the non-linear imaging market and has been qualified with the widest range of commercial inverted or upright multiphoton microscope platforms available.
Chameleon Ultra Applications:
• Multiphoton Excitation (MPE) Microscopy
• Non-linear Optics
• Time Resolved Spectroscopy
