Quality You Can Trust

Every product undergoes:

• Interferometry Testing: Validate surface flatness using state-of-the-art Zygo interferometers, generating sub-nanometer resolution maps to confirm compliance with λ/10 standards across the entire optical surface. This rigorous process ensures that even microscopic irregularities—imperceptible to conventional tools—are identified and corrected, critical for high-precision applications like semiconductor lithography and quantum interferometry, where surface flatness directly impacts beam coherence and measurement accuracy, eliminating errors that could compromise experimental results or manufacturing yields.​
• LIDT Validation: Certify damage thresholds through ISO 11254-compliant testing, exposing coatings to controlled laser pulses (1064nm, 10ns) to determine maximum energy handling before degradation. Results are third-party verified, ensuring reliable performance in high-energy laser systems—from industrial cutting tools to defense-directed energy weapons—where exceeding damage limits would cause catastrophic failure, downtime, or safety risks. This validation guarantees 10kW+ continuous-wave operation without coating burnout, even after prolonged use in harsh environments.​
• Angular Tolerance Checks: Ensure ±5′ offset accuracy using precision goniometers and automated alignment systems, verifying that optical components maintain precise angular positioning under thermal and mechanical stress. This meticulous testing is vital for applications like satellite laser communication and aerospace targeting systems, where even minute angular deviations would misalign beams, reducing signal strength or targeting precision. By confirming stability across temperature cycles (-40°C to 125°C) and vibration testing, these checks guarantee consistent performance in real-world operational conditions.
