Optical Assembly Product Development

Gimbal - Close-up of a gimbal-mounted electro-optical/infrared (EO/IR) sensor system on the underside of an unmanned aerial vehicle (UAV). The sensor housing includes multiple optical windows, revealing internal lenses and electronic components used for surveillance and targeting applications. The aircraft is stationed on a tarmac.

Precision Optical Assemblies for Demanding Applications

At G&H, we design, engineer, and manufacture precision optical assemblies that enable mission-critical performance across defense, industrial, and life-science systems. From targeting and imaging modules to analytical and diagnostic instruments, our assemblies deliver optical precision, environmental stability, and manufacturing scalability.

With more than four decades of photonics and systems-engineering expertise, we transform complex optical concepts into robust, production-ready assemblies - optimized for performance, cost, and compliance.

Integrated Optical Design and Development

Our multidisciplinary engineering teams combine optical, mechanical, and electronic disciplines to create assemblies that meet the highest standards of reliability and reproducibility. We manage the entire development lifecycle - from optical design through prototyping, validation, and transfer to full-scale manufacture.

Our Capabilities Include:

  • Optical Design & Simulation – lens and mirror design, ray-tracing, tolerance analysis, and optical system modelling.
  • Opto-Mechanical Engineering – structural design, precision alignment, mounting, and thermal management for long-term stability.
  • Prototyping & Testing – rapid prototype builds, interferometric testing, and environmental qualification.
  • Design for Manufacture (DFM) – scalable, repeatable assembly processes with cost-optimised yields.
  • Verification & Validation – optical performance, throughput, and durability testing under ISO 9001, ISO 13485, and AS9100 standards.
  • Integration & Transfer to Manufacture – calibration, documentation, and validation for consistent, high-volume production.
