PRECISION LENSES

Custom precision lenses are a key optical component for many transmission and imaging applications in the aerospace, security, defense, machine vision, health care, and life science industries.

G&H manufacture custom precision lenses for imaging, focusing, collimation and illumination, using standard polishing and grinding techniques, as well as single point diamond turning and MRF®.

We take a design-for-manufacture approach to lens production, facilitating the production of cost-effective, high quality custom precision lenses.

Our lens processing capabilities include CNC generating, grinding, and polishing. We polish spherical, semi-spherical, and aspheric lenses. 5-axis grinding and polishing machines are utilized for manufacturing high precision aspheric surfaces on optical glass. Single point diamond turning is used for aspheric and diffractive optical elements.

A unique, stand-out capability for G&H is our ability to manufacture complex shapes on lenses, such as step profiles or off-axis shapes.

In addition to singlets, we produce a wide variety of doublets, triplets, and more complex lens assemblies.

From high transmission broadband anti-reflection coatings to V-coats for high energy applications, our extensive coating capabilities deliver performance across the spectrum from the UV to the FIR.

We have made significant investment in metrology equipment to ensure that our customers receive quality, high-performing products. More details on our metrology capabilities can be found in the metrology section of the catalog.

Environmental testing of components and coatings is critical for assurance of performance in rugged conditions. G&H environmental testing capabilities include MIL-C-675C, MIL-C-48497A, MIL-E-12397, and MIL-M-13508C for endurance against abrasion, adhesion, humidity, temperature, and environmental conditions.
