Cobolt SkyraTM is an extremely compact, permanently aligned, plug & play, multi-line laser with up to 4 laser lines and control electronics integrated into one single, temperature-controlled package, small enough to fit in the palm of your hand!
The laser is built using Cobolt’s proprietary HTCure™ manufacturing technology for robustness in a compact, hermetically sealed package. HTCure™ results in an ultra-stable, permanent alignment of optical elements, with very precise and stable overlap of the combined output beams.
The Cobolt SkyraTM is available in a free beam or fiber coupled configuration. It is intended for stand-alone use in laboratory environments or for integration as OEM components in instruments for applications including biomedical re- search, fluorescence microscopy, flow cytometry, as an Argon ion replacement in microscopy instrumentation and optogenetics.
