This production-ready, easy-to-integrate laser system enables high quality laser marking with low maintenance and operating costs. The C-40 is ideal for laser processing of many materials, including paper, plastics, wood, leather, cloth and more. The C-40 is part of the Coherent C-Series family of products which offer a full range of power levels – from 20 W to 70 W. Based on a sealed waveguide and integrated RF power supply design, the C-40 boasts outstanding production-proven reliability (lifetime >50,000 hours), while delivering superior beam quality and power stability in a compact, flexible and integrated package. The modular platform design provides cost-effective optimization of operating wavelength (from 9.3 to 10.6 μm) and cooling configuration (air/liquid), enabling rapid adaptability to changing applications and market needs. • Versatile power range with high stability and reliability • Industry leading compact size with integrated RF power supply • High quality laser processing on a wide range of materials • Wide power range with constant wave (CW) or pulse width modulation (PWM) control • Available in multiple wavelength and cooling configurations (air or liquid)

Notes: 1. Power measured at 25°C and derated by 1%/C for higher laser hea d temperatures. 2. Power stability based on ±(Pmax - Pmin)/(2*Pmax) average power measurement at constant duty cycle after 10-minute warm-up at operating condition. 3. The overall height dimension is taller for the Dual Chillplate version of this item. 4. Optional fans add 1A. 5. Dow Frost is a trademark of the Dow Chemical Company.
