Coherent BioRay and StingRay Diode Laser Modules

Compact lasers with fiber-ready (FR) or elliptical beam output and user-adjustable focus, ideal for particle counting.



With a compact modular design measuring only 19 mm in diameter and using the industries' premier laser diodes, the StingRay delivers best-in-class performance. High-quality glass optics and sophisticated drive electronics deliver the power and control to your application to improve signal-to-noise and measurement speed. StingRay is the highest-performing top-hat-profile laser available that comes in a variety of fan angles to create the line you need for measurement and profiling applications.


Offering the same focus adjustment as the BioRay, the StingRay allows the user to optimize the focus location for the best measurement resolution. BioRay is a Stingray with an included Heat Sink and Mounting Plate for Life Science applications with an elliptical beam output and a user-adjustable beam divergence (adjustable focus).


BioRay combines power and flexibility, like no other product on the market, delivering:

  • High Signal-to-Noise with superior Contained Power in the line
  • 405 nm to 830 nm
  • Power up to 200 mW
  • User adjustable focus
  • Pointing stability <10 μrad/°C
  • Analog or digital modulation
  • Microprocessor controlled
  • Onboard diagnostics monitor
  • RS-232 control option
  • Power supply range: 5 to 24 VDC
  • ESD protection, over-temperature protection, and reverse polarity protection
  • Optional fibre-ready version
