Laser Innovations is proud to be the first to offer this New "drop-in" 488nm Solid State Laser system; for easy replacement of the old Air-Cooled Argon Ion laser system found within many OEM applications.
This new Model (LI-488-20-BD) of Solid State laser is specifically designed to replace your "noisy little hair dryer" Argon Air-cooled OEM laser found within your Becton Dickinson FACS brand, and Beckman Coulter bench top instruments and analyzers. |

"The availability of a reliable solid-state replacement laser represents a turning point in benchtop flow cytometry. The convenience of reduced size and heat output combined with long lifetimes and excellent beam qualities in this 20mW 488nm unit makes it the obvious choice when replacing older ion lasers or upgrading FACS instrumentation. The beta units performed admirably in our lab and the final product is representative of the quality workmanship we've come to expect from Laser Innovations."

$32,474.00 - Total Savings
$10,825.00 - Total Annual Savings The average usable lifetime of an argon ion laser is approximately 5000 hours, upon which the average end of life power observed is ~5-10 mW of 488nm. In order to achieve the desired
15 mW at the fluorescence point within the machine, the average laser needs to run at approximately 20+ mW at the head to counter the usual optical path losses, such as the external steering mirrors, optics, and lenses found in the machine. In order to maintain this desired power level for peak performance, the tube current must be continuously raised over the life of the laser. The solid state laser has an initial output power of 20 mW and remains at 20 mW after 5000 hours. Additionally, there is no discernible increase in the utility requirements such as those required by an aging argon ion laser to maintain output power.
