Dual-line light engine for optogenetics by Cobolt

Cobolt Dual Combiner dual-line light engine

Developed for applications in optogenetics, the Dual Combiner dual-line light engine from Cobolt (Solna, Sweden) delivers 473 and 594 nm emission wavelengths—at up to 50 and 100 mW, respectively—for light-activated proteins. An integrated, silent SRS shutter modulates the output beam at up to 100 Hz with a <350 μs rise time, maintained 3% power stability, and RMS noise <0.3%.

Modulated Cobolt Dual CombinerTM  473+594 nm for Optogenetics
Cobolt, Swedish manufacturer of high performance DPSS lasers, announces the release of a modulated dual-line light engine optimised for high-end Optogenetics research applications. This version of the Cobolt Dual Combiner offers two attractive emission wavelengths for light-activated proteins; 473nm (up to 50mW) + 594 nm (up to 100mW) from one small box. Through the integrating of a silent SRS shutter, the output beam can be modulated at up to 100 Hz with a very short rise time of <350 μs and with maintained 3% power stability and an RMS noise of <0.3%. Each line can be individually addressed through a software application provided with the lasers, or through RS232/USB communication.

The modulated Cobolt Dual Combiner™ is perfectly suited for Optogenetics applications where high level of power stability and control of the delivered energies are required. The use of Cobolt’s unique HTCure Technology™ for laser manufacturing provides a very high level of robustness and insensitivity to ambient conditions, which ensures excellent beam overlap and beam pointing stability. The modulated Dual Combiner is also available with any other 2-line combination of the Cobolt 04-01 series lasers.

The modulated Cobolt Dual Combiner™ for Optogenetics will be displayed at Neuroscience 2011, booth #1102, in Washington DC.
