Coherent Chameleon Vision Lasers (I & II)
The Chameleon Vision lasers build on the dependable and innovative Chameleon Ultra Ti:Sapphire platform by adding dispersion precompensation to maximize peak power where it counts – at your sample plane.

Ultrawide Tuning Range
Chameleon Vision’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.
High Image Resolution and Optimal 2 Photon Excitation Efficiency
Careful design ensure the pristine beam parameters of the Chameleon Ultra cavity are preserved through the dispersion precompensation stage, ensuring lowest losses through your microscope and lowest astigmatism in the excitation plane, which in turn delivers best image resolution and optimal 2 photon excitation efficiency.
High Precompensated Power
Chameleon Vision lasers deliver highest precompensated average power of any automated Ti:Sapphire laser, and as such form a perfect pump source for the Chameleon MPX wavelength extension OPO. This extends tuning to 1340 nm, also with dispersion precompensation, ideal for red shifted probes and techniques such as Third Harmonic Generation and CARS.
Reliability
Chameleon Vision lasers are qualified and proven on all major commercial two-photon microscope platforms. All Chameleon lasers are HASS tested to ensure highest product reliability, and benefit from Coherent’s acclaimed Advanced Replacement (ARU) service strategy to maximise system uptime.
