Spherical Lenses

Precision molded spherical lenses remain a cornerstone of optical design for focusing, collimation, and imaging. At G&H | GS Optics, we produce custom spherical polymer lenses that deliver consistent performance, exceptional surface quality, and scalable manufacturing for high-volume applications. Our Rochester, NY facility combines over a century of polymer processing expertise with precision metrology to meet demanding optical and mechanical tolerances.

Applications

• Imaging and illumination systems
• Biomedical diagnostics and instrumentation
• Laser collimators and focusing assemblies
• Machine vision and sensing modules
• Consumer and AR/VR optics

Manufacturing Expertise

Spherical polymer lenses are molded directly from precision-machined inserts, allowing high-accuracy replication of curvature and surface form.

Manufacturing Capabilities

• Diameters from 2.5 mm to 150 mm
• Single or double-convex/concave geometries
• Multi-cavity tooling for efficient mass production
• Diamond-turned master tooling and inserts
• In-house AR and HR coatings for visible and NIR bands
• ISO Class 7 cleanroom assembly

Advantages of Spherical Polymer Lenses

• Cost efficiency: Injection molding replicates optical surfaces at a fraction of glass-grinding cost.
• Material versatility: Optical-grade thermoplastics tuned for visible or NIR transmission.
• Lightweight design: Two to five times lighter than glass - ideal for portable or weight-sensitive systems.
• Integrated features: Mechanical mounts or alignment datums can be molded into the lens body.
• High-volume repeatability: Tight process control delivers uniform optics from thousands to millions of parts.

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.

Material Selection

We select materials according to optical performance, mechanical robustness, and environmental demands.
