From the Kiel Canal to the Milky Way: Examples of our work.

Our optical components are used all over the world wherever the highest technical precision is required: from the world of analytics, via security and medical technology to air- and space travel. Looking to the future is crucial – not just in the exploration of space but in the constant evolution of our technical capabilities. The businesses and research facilities we work with constantly set us new challenges, which we are always eager to accept. Now and in the Future.

SPHERE Polarimeter for searching exoplanets / Astron Lenses are optical components with two refractive faces, of which at least one is convex or concave. The most important property of a lens or array of lenses is its imaging properties. The most crucial aspect of a lens is its focal length, i.e. the measure of how strongly the system converges (focuses) or diverges (defocuses) light. The simplest lenses are spherical lenses: their two surfaces are parts of the surfaces of spheres, with the lens axis ideally perpendicular to both surfaces. Each of the surfaces can be convex (bulging outwards from the lens) or concave (depressed into the lens). As such, the surfaces can be assigned radii of curvature. A distinction is made between converging lenses (two convex faces or one convex and one planar face; ideally, a beam of light running parallel to the optical axis is collected in one point, the focus) or diverging lenses (two concave faces or one concave and one planar face; a beam of light after passing through the lens appears to be emanating from a particular point on the axis in front of the lens., Mirrors, windows from CaF2, Fused Silica, Infrasil, S-NSL36 2009 - 2010
