Specifications
Engineering Expertise
Based on decades of expertise, G&H | GS Optics engineers provide our customers with DFM recommendations to ensure that their polymer optics programs are successful. Using mold flow simulations, we can model how resin will fill the mold during the injection molding process to better position gates, anticipate where knit lines will appear, and locate difficult to fill spots in the mold. G&H | GS Optics specializes in scientific injection molding which is a systematic, data-driven methodology to produce world class polymer optics.
Prototypes are diamond-turned using Precitech Nanoform 200 and Nanoform X systems, achieving nanometric surface finish without post-polishing. The same tooling precision transfers directly into injection molds for scalable production.
Quality Assurance and Process Validation
All polymer optics produced by G&H | GS Optics are subject to rigorous quality standards to ensure consistent, reliable performance. Each lens is measured using a variety of metrology equipment to verify dimensional accuracy, surface quality, and refractive characteristics.
To reduce risk after transferring from development to production, GS Optics can conduct a process validation through a combination of installation (IQ), operational (OQ), and performance (PQ) qualifications, ensuring process repeatability and consistent optical performance.
