Coherent Chameleon Vision-S

Highest Peak Power

Chameleon Vision-S delivers the highest peak power at the sample, providing at the same time the broadest tuning range among automated short pulse Ti:Sapphire lasers designed for non-linear imaging.

Automated Dispersion Precompensation in a Single Box

The exceptional performance enables Chameleon Vision to easily manage pulse duration and excitation wavelength, providing brighter images and better sample viability. The built in pre-compensation provides a user friendly method to optimize pulse width at the focal plane, to study the interplay of peak power, average power and pulse duration on different samples. For example, by mismatching the pre-compensation, it is possible to vary the pulse duration at the sample between the fully compensated value of 75 fs to chirped pulse durations of several hundreds of femtoseconds.

Flexibility

The flexibility of the Vision family makes it ideal not only for microscopy but also for time-resolved spectroscopy and Terahertz studies.

Reliability

Chameleon Vision lasers are qualified and proven on all major commercial twophoton 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.
