Newport's Excelsior-594 Laser targets flow cytometry, DNA sequencing

May 21, 2008 -- Newport Corporation's Spectra-Physics Lasers Division has unveiled its new Excelsior-594 Laser, designed for flow cytometry and emerging microscope and DNA sequencing applications that rely on exciting fluorescent dyes like "Texas Red" by using 594 nm as the laser excitation source.

Newport/Spectra-Physics says that the new release, the latest member of its popular product line (which includes the Excelsior-505 announced earlier this year), is a state-of-the-art multi-longitudinal mode laser with 30 mW of output power at 594 nm. "Three years ago, when we introduced our first Excelsior laser, our goal was to provide a complete product family of lasers for the next-generation applications being developed by our leading OEM customers," said Jürgen Niederhofer, Product Manager for Spectra-Physics. "Over the last 36 months, we have continuously expanded and enhanced the product offerings, and today we are very excited to release the 12th member of the Excelsior family."

The Excelsior laser platform includes low power continuous wave (CW) lasers at 375, 405, 440, 473, 488, 505, 532, 561, 594, 635, 785, and 1064 nm. Spectra-Physics says they are excellent tools for a variety of OEM applications because they provide superior optical beam quality, exceptionally low optical noise, and high reliability. Promising the smallest footprint in their class, the Excelsior lasers are stand-alone devices that are designed for ease of use. An integrated active light loop guarantees that every Excelsior laser delivers outstanding output power stability over a wide temperature range, the company says.
