Fourteen wavelengths are now available in the Excelsior One compact laser system for bioinstrumentation
Compact lasers for Bioinstrumentation

Spectra-Physics, a Newport Corporation brand, announces the expansion of the Excelsior One continuous wave (CW) lasers series. Three new wavelengths of 515, 553, and 594 nm have been added, resulting in a total of 14 wavelengths available from the Excelsior One platform of compact, integrated lasers. The expanded series offers the largest variety of diode-pumped solid-state (DPSS) and direct-diode laser technology offered today. The lasers are ideal for use in flow cytometry, confocal microscopy, DNA sequencing, and other bioinstrumentation applications.

The new Excelsior One models deliver output powers of 50 mW at 515 and 553 nm. The 594 nm wavelength model features advanced, high-output power of 100 mW, making it the highest power output in a package that is at least 3.5 times smaller than any competitive product.  The product family includes direct diode and DPSS technology in a consistent, single and compact footprint with a common electronics interface.

“Spectra-Physics’ expanded line of Excelsior One lasers is perfect for customers who need flexibility in configuring their instruments with a wide variety of wavelengths in the same footprint,” states Wolfgang Köhler, product manager for Spectra-Physics (Stahnsdorf, Germany). “These lasers are a reliable and simple solution for a wide range of fluorescence-based bioinstrumentation applications.”

The Excelsior One platform is based on Spectra-Physics’ It’s In the Box design, where the laser cavity and control electronics are integrated into a single, compact package, thereby eliminating unnecessary cables and external controllers. All lasers deliver TEM00 mode quality and very low optical noise for highest signal-to-noise ratio. The DPSS models are available in single or multi-longitudinal mode versions.  Easy to configure, all models are equipped with a RS 232 software interface, and the direct-diode models include high speed modulation (TTL and analogue).
