Optics - From components to systems and services
Various shapes, materials and refinements - countless application possibilities
Optical components can be used in a variety of everyday, technical and industrial applications. The shapes, materials and finishing possibilities of optics are as extensive as their use. As a reliable partner, asphericon offers custom-made solutions for your individual optical requirements; from optical design to a targeted development and manufacturing process to after-sales service. Let our products convince you with their outstanding quality, highest precision and long-lasting functionality.
A specially developed and patented technology for the control of CNC grinding and polishing machines, with the ability to simulate machining processes, forms the manufacturing basis at asphericon. Whether prototype construction, small quantities or series production: Thanks to our unique technologies, we produce optics for a wide variety of materials and geometries with high precision for all wavelengths, from spherical lenses to asphere, acylinders, plano optics and diffractive optical elements. Each asphericon optic contains the compressed knowledge and experience from a multitude of challenging projects that can perfectly complement your individual project.
At asphericon, the efficiency of an optical system can be further increased by means of high-end finishing processes by correcting local shape defects. Ultra-precision machining includes ION-Finish, Magnetorheological Finishing-Technology (MRF) and the specially developed asphericon Angstrom-Polishing. The surface correction methods achieve roughness values of up to 5 Å (measuring range 1000 x 1000 µm, Rq according to ISO 10110). Our coatings can additionally refine optical elements for a wide variety of applications - no matter whether it is an optic produced by asphericon or an optical component provided by you. We offer high-quality surface coatings across the entire spectrum, from UV to the near infrared range.
Convince yourself of the quality of our ISO-tested optics (production chain certified according to DIN ISO 9001) and get a variety of customer-specific optical elements (Custom line) and stocked standard optics (StockOptics line). The StockOptics range available in our webshop includes precision-polished aspheres, axicons and acylinders, combined with the cost benefits of mass production. Selected lenses are also available as mounted versions and can therefore be integrated into applications even faster.
For individual design requirements, our in-house optical design department will be happy to advise you on everything from analysis and conception to final implementation. In addition, asphericon offers numerous optical services. These include, for example, optical characterizations based on high-resolution wavefront measurements or optical measurements that can be carried out quickly and easily thanks to extensive tactile and interferometric measuring instruments.
asphericon is also dedicated to research and further development, for example in the field of freeform optics. Following the trend towards miniaturization, asphericon's freeform systems are convincing not only because of the unique complexity of optical surfaces and small number of optical elements required, but also because of their excellent imaging properties. This opens completely new possibilities in the field of optical design, as they are free from the limitations of traditional manufacturing geometries.
Whether optical design, production, coating and/or research project - we look forward to your individual inquiry and are happy to advise you. Our contact form can be found here.




In contrast to aspheric lenses, the shape of an axicon resembles a cone. The conical shape of the axicon generates a ring-shaped beam profile. The diameter of the ring beam depends on the axicon angle and decreases as the distance between the axicon and image plane grows. The ring width remains constant...


Acylinders, also known as aspherical cylinders, denotes cylindrical-surface-shaped lenses, the cross-section of which differs from the circular shape. In practice, plano-concave and plano-convex cylinders are used as well as those with a spherical or aspherical reverse...


The group of aspheric mirrors also includes paraboloids, hyperboloids and ellipsoids. These, as well as mirrors with a customer-specific aspherical surface, are among the specialties of asphericons product range...


Spheres are used to collect, diverge or focus light. They are used for various technological applications, for example in medical technology and semiconductor industry, or as a component in achromatic lens systems...


Freeformed optical surfaces without rotational symmetry allow the implementation of completely new concepts for optical systems. The use of freeforms reduces the number of elements in an optical system, allowing smaller, lighter and more efficient systems...


Conventional beam expansion systems can only be adapted with great effort, are relatively large and only suitable for a certain wavelength. The world’s first use of an aspheric lens for beam expansion opens completely new possibilities. Spherical aberrations are corrected and an afocal system for large input beam diameters is realized...
