APPLICATION:The ideal application for this laser (actually three lasers in one) is for fluorescence microscopy.
Those specific wavelengths are the perfect excitation source for common fluorescent dyes used in biological research. Namely FAM (fluorescein), HEX Cy3.5, and Cy5. Moreover, their combination into a small box with a single fiber output, their incredible power density at the output of the fiber, and their power stability leaves plenty of engineering flexibility for an optical microscopy researcher to integrate into their setup.

Cobolt Skyra™ is an extremely compact, permanently aligned, plug & play, multi-line laser with this particular one sporting 3 laser lines and control electronics integrated into one single, temperature-controlled package, small enough to fit in 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.
