Lenses

In laser technology, optical lenses are used to focus and shape laser beams. Convex lenses (converging lenses) are thicker near the optical axis than at the edge and are used to focus the laser beam. Concave lenses (diverging lenses) are thinner near the optical axis than at the edge and disperse the laser beam. Cylindrical lenses are only curved in one axis and are used for linear focusing. Meniscus lenses (convex-concave shaped) and aspherical lenses are used to shape and optimize beams by minimizing spherical aberrations.

We manufacture spherical, aspherical and cylindrical lenses from different optical materials such as fused silica, ULE, Zerodur, N-BK7, calcium fluoride or silicon.

The following lens shapes can be manufactured in the company's own fine optics production facility: plano-convex, plano-concave, bi-convex, bi-concave, convex-concave, menisci, spherical-cylindrical, crossed cylindrical. Toric surfaces and other free shapes are also possible.

For spherical lenses, diameters from 3 mm to 600 mm are possible in combination with any radii of curvature. Centering is carried out according to customer requirements. We achieve an accuracy of up to 1 minute. Geometries with D-cut or angular shapes can also be produced.

Cylindrical lenses can be manufactured with edge lengths from 5 mm to 2000 mm. Any radii of curvature are possible here too.

Upon request, the lens edges can also be polished and/or metallized.
