Challenge
The client required optics for a high-power 10kW CO2 laser cutting system. Key challenges included:
- Maintaining beam quality at extreme power levels
- Minimizing thermal lensing effects that degrade cut precision
- Ensuring long operational lifetime in 24/7 manufacturing environments
- Reduced absorption to prevent optic damage at high power densities
Solution
We provided custom ZnSe optics with optimized specifications tailored for high-power CO2 laser applications:
- Ultra-low absorption ZnSe (<0.0003 cm⁻¹) material grade
- Custom meniscus lens design for reduced spherical aberration
- Enhanced AR coatings specifically engineered for high-power operation
- Precision surface finishing to 10-5 scratch-dig quality
- Full material characterization with absorption mapping
Results
The solution delivered exceptional performance results:
- 99.7% transmission at 10.6μm wavelength
- Reduced thermal lensing by 40% compared to previous supplier
- Extended optic lifetime to 2000+ hours of continuous operation
- Improved cut quality with 25% faster processing speeds
- Zero optic failures reported in first year of deployment
Client Testimonial
"OPTOstokes-IROptical's ZnSe optics exceeded our expectations. The thermal performance at 10kW has been outstanding, and the consistency from batch to batch is remarkable. We've reduced our optic replacement costs by 35% while improving our cutting quality." - Senior Optical Engineer, Laser Systems Division
