Compass Lasers News...

Compass 115M allows OEM integrators to immediately benefit from shorter processing times in life sciences and inspection applications.

Compass (COMpact All Solid State lasers) is a family of solid-state lasers in the green (532 nm). They exhibit optical properties unmatched by other products and are known for their outstanding level of reliability and lifetime. This is the reason OEM customers have chosen to integrate Compass more than 65,000 times making Compass one of the most successful products in laser history.

Excellent laser beam parameters, highest unit-to-unit consistency, hands-free operation plus superior reliability and lifetime make the Compass the recognized industry standard in demanding applications such as medical diagnosis or cytometry. 

Compass 115M
CW green laser with best performance-to-price ratio featuring excellent laser beam parameters and output powers of 5 mW, 10 mW, 15 mW and 20 mW.

Compass 115M
 Continuous wave (CW) green lasers (532 nm), from 5 mW to 20 mW.
  Compass 115M
Power (mW) 5, 10, 15, 20
Wavelength (mW) 532

All Compass models utilize intra-cavity frequency-doubling to convert IR to green laser light. This is realized with Coherent’s unique, patented PermAlign technology: optical components are aligned to optimum and then permanently fixed by soldering making the lasers optimally aligned over their whole lifetime, insensitive to vibration and thermal cycles. The lasers are manufactured in controlled clean rooms and hermetically sealed before being end-tested extensively.

  • Patented PermAlign technology: solder-bonding optics for unsurpassed unit-to-unit consistency, ruggedness and thermal stability
  • Outstanding beam quality over entire laser life
  • Highest power stability and lowest amplitude noise for superior application results
  • Contamination-free cleanroom manufacturing and hermetically sealed laser heads for highest reliability and lifetime

A new 20 mW Compass 115M model completes the 115M line of green CW lasers. These 532 nm lasers are ideally suited for cost-sensitive, yet demanding OEM applications in life sciences, graphic arts, and inspection. The 115M line offers excellent optical performance and the same reliability, unit-to-unit consistency and long lifetime as higher power Compass lasers. The line therefore offers the best available performance to price ratio and lowest cost of ownership.
