Read our recent mention in an article from the January 2019 edition of Laser Focus World which discusses visible laser sources for flow cytometry. Read how the Cobolt Skyra multi-line laser is allowing more compact flow cytometry systems with increased functionality.

Single and Multi-line lasers for flow cytometry

Because flow cytometers often require more than one wavelength, multiline lasers are a natural for this purpose. Cobolt (Solna, Sweden) has provided the flow-cytometry market with standalone high-performance lasers over the visible spectrum for many years, notes Håkan Karlsson, the company’s CEO. “Originally, it was our DPSS laser technology with high powers of 532 nm and 561 nm which made Cobolt lasers attractive to the flow community, and in later years our diode-laser portfolio.” More recently following the market request for more compact, easy-to-use lasers, the company introduced a multiline laser—the Cobolt Skyra, Karlsson adds.

The Skyra combines up to four individual laser wavelengths, which are permanently aligned using a method that is patent-pending. “The idea was to be able to offer a single compact package that could be used like a single-line laser: that is, an easy-to-use, robust laser with no need for realignment,” Karlsson says. He also notes that the lasers are made via the company’s HTCure manufacturing method, which he says allows the light sources to meet the beam overlap, power stability, and noise specifications needed for flow cytometers (the HTCure includes matching coefficients of thermal expansion of components so that they are unaffected by the high-temperature baking process. In addition, Cobolt offers customized offset line focus optical designs, which are typically requested from the flow market.
