Precision lenses are crucial optical components for a wide range of applications in industries such as aerospace, security, defense, machine vision, healthcare, and life science. At G&H, we specialize in the manufacturing of custom lenses for imaging, focusing, collimation, and illumination purposes, utilizing standard polishing and grinding techniques, as well as singlepoint diamond turning.
Applications for our precision lenses include: dental imaging, dermatology, endoscopy, hyperspectral imaging, lasers, machine vision inspection, metrology, optometry, projection, range finding, reconnaissance, surveillance, target identification, targeting and designating, and thermal imaging.
Design for manufacture
Our lens production process follows a design-for-manufacture approach, ensuring the production of cost-effective, high-quality custom lenses. We have CNC generating, grinding, and polishing capabilities for spherical, semi-spherical, and aspheric lenses, including high-precision aspheric surfaces on optical glass produced using 5-axis grinding and polishing machines.
