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.
Equipment location:
MN
Additional information:
Used for only a few hours to generate data on a grant. Like new. 457nm 50mW (all powers listed at fiber output) 561nm 50mW 647nm 50mW Heat sink with fans S&K SM/PM 2m fiber Direct intensity modulation of each line individually, fast and deep modulation from versatile input signals with complete dark state capability • Compact, robust package with integrated electronics • Intergrated fiber coupled • User friendly graphical software interface 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.
