New OBIS Galaxy - Laser Beam Combiner

Beam combiner for plug-and-play simplicity across the spectrum. 

  • Eight input channels
  • Single output
  • Compact
  • Robust
  • Easy to connect
  • Hands free operation - no adjustments required
  • Solid performance over storage, temperature, shock/vibe

OBIS is a breakthrough laser platform offering plug-and-play operation with  the widest range of wavelengths available. With lasers from 375 nm to 785 nm, an integrated controller and compact packaging, OBIS is the smallest - and smartest - laser platform on the market. Simply plug in the DC source and your laser is operating. Need a different wavelength? Unplug the old and plug in the new. It's as simple as that. 

Featuring the same footprint and beam propagation across all OBIS units saves integration costs and time to market for OEM customers and end users as well. With its unique feature set, OBIS answers the need to cover a rapidly expanding range of wavelengths in Life Sciences and other instrumentation applications.

Coherent has set the standard in reliability for life sciences and other instrumentation applications with its laser diode and optically pumped semiconductor laser based solutions. Different technologies continue to serve a demand for distinct wavelengths.

Laser Diode technology. OBIS LX diode solutions represent the leading industrial design for diode modules with ESD protection, thermal management with TEC stabilization and unit to unit consistent superior spatial beam quality.

Optically Pumped Semiconductor Laser (OPSL) technology. OBIS LS solutions use Coherent's proprietary OPSL (Optically Pumped Semiconductor Laser) technology. OPSL technology is well proven over several years with more than twenty thousand installed lasers in both laboratory and rugged field applications. Its superior reliability ensures consistent uptime and the lowest cost of ownership in both demanding industrial and research applications. A key performance benefit of OPSL is the superior low noise enabled by the short upper state lifetime of the semiconductor gain medium (no green noise problem). The thin semiconductor gain medium eliminates the limitations to change output powers known from other conventional DPSS lasers. The absence of thermal lensing in an OPSL allows varying the output power to meet application needs while taking advantage of invariant beam parameters.
