Solaris Optics manufactures custom aspheric lenses in its premises in Poland.

An optical element, such as a lens or a mirror, has typically of a least one spherical surface (concave or convex). However in applications with special requirements a more advanced shape may be necessary, including e.g. aspheric optical surface. A lens with at least one aspheric surface is an aspheric lens.

Aspheric lenses are characterized by a surface having such a more complex shape, slightly divergent from spherical (e.g. ellipse, parabole, hyperbole). The role of this aspheric optical surface is to compensate for spherical aberration of an image and an optical system. Typically a single aspheric optical surface is sufficient to obtain the required system characteristics. The result is an overall better quality image and more details further from the optical axis.

Applications of Aspherical Lenses

Apheric lenses are found most useful when it is needed to reduce or control the size of an optical system. A single aspheric lens oftentimes replaces a multi-lens system, giving the same result of an image quality, however without unnecessary expansion in size.

As such aspheric optics is of use for instance in mobile devices, e.g. cameras. Aspheric lenses can be found also in space optics, such as in our Tele-Objective Earth Observation Project with ESA.

Manufacturing of Aspheric Lenses

In Solaris Optics apheric lenses are produced by CNC grinding, conventional polishing, CNC polishing as well as via MRF technology.
With corrective polishing (MRF) technology Solaris Optics is able to make mild aspheres from flat or spherical surfaces up to about 10-15μm.
