Where to Buy Aspheric Optics

Lens processing capabilities of G&H 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.

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.

Ex-stock delivery of standard plano-convex aspherical lenses made of N-BK7 or high refractive index N-LAH64 glass. We can produce custom design aspheric lenses in our CNC lens polishing facility. Lenses can be supplied with anti-reflection coatings to suit your particular laser application.

Precision aspheric lenses reduce visual defects and produce clearer images, making them ideal for many applications. In addition, because the surface of an aspheric lens is designed and formed to effectively reduce aberration in specific applications, custom aspheric lenses make flexible solutions to complex problems. At Shanghai Optics, we use two main methods to produce custom aspheric lenses: molding and traditional polishing with the state-of-the-art manufacturing and metrology equipment.

A cost-effective alternative to multi-lens systems, aspheric optics are commonly used to correct spherical aberrations that may hinder optical performance. Available from stock or as custom-made components, our wide range of high-quality aspheric optics include precision-grade, plastic, fire-polished and diamond-turned lenses.

Edmund Optics offers various aspheric lenses, including CNC polished lenses, infrared lenses with diffraction-limited performance, precision glass molded lenses, color-corrected lenses, condenser lenses and plastic molded lenses.

We produce metal mirrors including diamond turned aluminum and polished nickel-plated aluminum and beryllium aspheres. Format sizes up to 500 mm and shapes to include off-axis parabolas, aspheres, toroids, and flats. Metal mirrors can be light weighted and configured with integrated mounting features.
