Customer-specific spherical optics for complex systems and assemblies

Spherical Optics.

Exceptional Imaging and Beam Quality.

We produce spherical optics for your most demanding applications in imaging and multi-spectral systems (e.g.: digital aerial cameras) as well as in LASER-based technologies (e.g. femtosecond lasers, high-energy lasers, 193nm optics…).

Metrology/QA Spheres:

  • Interferometry incl. radius metrology
  • White light interferometry
  • High-precision, non-contact and scanning
  • metrology for ∅, center thickness and roundness
  • 3D-coordinate metrology (tactile & optical)
  • Various microscopy technologies

Our competences

  • In-house complete production from pre-processing of raw materials through coating and  lacquering
  • Flexible and controlled production technologies
  • Maximum precision lenses (λ/100 PV; λ/500 RMS), made by deterministic methods
  • Lenses for various LASER applications (special polishing process)
  • Lenses with the highest quality and  low surface flaws
Shaped lenses
Shaped Lenses
  • Lens production and the ability to produce and check  external geometries up to a repeatable accuracy of 3µm 
  • Metrology and alignment technologies integrated in the process permit positional tolerances (e.g. optics to mechanics) of up to 3μm alignment and 10sec of tilt.

Composite lenses
  • Aerial photography lensAlignment under collimators, autocollimators or directly under the interferometer with a simultaneous check of the transmitted wave front
  • Possibility of free shaping, even when cemented and in terms of the optical functional surfaces
