Chameleon Vision from Coherent Intended to Maximize the Potential of Multiphoton Microscopy Techniques

The new Chameleon™ Vision from Coherent Inc. (Santa Clara, CA) (Nasdaq: COHR) is a fully-integrated laser source for Multiphoton Excitation (MPE) microscopy that delivers both state-of-the-art image quality and superior ease of use. This is achieved because the Chameleon Vision combines the widest tuning range, the highest group velocity dispersion (GVD) compensation, the highest power, excellent pointing stability, and the smallest footprint of any true one-box MPE light source.

In particular, the high (47,000 fs²) GVD compensation means the Chameleon Vision can correct for the large GVD found in microscopes with many highly dispersive elements. Plus, the GVD compensation is fully adjustable across the entire dynamic range, even to zero, for maximum flexibility. Versatility is further enhanced by the extended wavelength tuning range (680 to 1080 nm), which enables optimum excitation of red fluorophores such as m-cherry. And the high output power (greater than 2.5 Watts) means the laser output can be optimized for both shallow and deep tissue imaging.

The Chameleon Vision is intended to maximize the potential of multiphoton microscopy techniques. All Coherent Chameleon lasers also feature high reliability and hands-free, sealed operation, in part due to their use of the long-lived Verdi™ pump laser.

Founded in 1966, Coherent, Inc. is a Russell 2000 Index company and a world leader in providing laser-based solutions to the commercial and scientific research markets.
