Our aspheric lenses are inspected and optically tested to ensure complete customer satisfaction. Visual cosmetic inspection for scratch/dig is performed on 100% of all lenses per MIL-PRF-13830B. Most lenses are guaranteed to pass 40/20 scratch/dig, but other inspection criteria, such as 60/40 or 20/10, can be provided upon request.

With this more sophisticated surface profile, an aspherical lens can reduce or eliminate both spherical and other aberrations, providing higher imaging quality such as a smaller focal point or a higher degree of collimation. Often, complex optical systems with multiple spherical lenses can be replaced by a single aspherical lens, resulting in less complexity, reduced dimensions, lower weight and often lower system costs.

Traditionally, aspheric lenses have been produced by complex grinding, CNC machining or diamond turning, but with advances in glass molding technology, precision molded glass aspheric lenses can now be produced at low cost while maintaining a high quality and durability, suitable even for high optical powers.

Our portfolio comprises a variety of lenses for different needs and applications that can be manufactured in diverse materials and customized based on specific requirements: spherical lenses, cylindrical lenses, achromatic lenses.

Product PortfolioIn addition to our ranges of standard  and infrared aspheric lenses available from stock, AMS Technologies also carries a series of these precision molded aspherics mounted in stainless steel holders – equipped with threads for screwing the components into your systems, but they can also be soldered or welded to suitable structures in the required position.

AMS Technologies offers a broad selection of molded-glass aspheric optics from stock, in sizes ranging from 2.4 mm to 11.0 mm outer diameter with focal lengths from 8 mm to 22 mm. With design wavelengths from 405 nm to 9500 nm, these molded aspheric lenses aim at applications in the visible (VIS), near-infrared (NIR) and mid-infrared (MIR) wavebands, such as small beam collimation, focusing, and fiber coupling, with our precision molded infrared aspheric lenses being ideal for coupling of quantum cascade lasers (QCL).

The cornerstone of "normal" lens designs in the f/1.7-f/2.0 class, the double Gauss formula originates with the Zeiss Planar of 1896. The classical version has six elements in a 1-2-2-1 configuration, symmetrical around the aperture stop.

Countless derivatives of this formula have been manufactured with variations including air-spacing rather than cementing the inner doublets; splitting the outer elements into two, and so on. Lenses in the f/1.0–f/1.4 class are frequently these modified double-Gauss designs.

DefinitionWhile the manufacturing and use of common spherical lenses (with both lens surfaces being part of surfaces of spheres, i.e. a spherical segment or spherical cap) are less complicated and expensive, the optical performance of spherical lenses is compromised by phenomena such as spherical aberration. So instead of a simple spherical lens, a more complex shaped lens is best suited for collimating and focusing tasks – an aspherical lens with at least one surface whose shape differs from a sphere. An aspheric lens surface typically is described by a radius of curvature and several parabolic or higher order terms.

Photographers may simply refer to a "Gauss" design lens. Strictly this is not correct, as Carl Friedrich Gauss had originally described a telescopic objective pairing a positive and a negative element. Using two Gaussian lenses back-to-back was the vital innovation for photography.
