Precision Optics

Accurate manufacturing of optical components from design to verification is the focus of the versatile manufacturing environment of son-x. Several ultra precision machines form the heart of our production chain for ultra high precision optical components and sub systems. We are specialized in high precision mirrors for space and semiconductor applications. With our unique technology of ultrasonic assisted machining we produce stainless steel inserts in optical quality for injection moulding. Additional optical products are prototype plastic lenses and infrared lenses from single piece to large volume.


Next to their outstanding optical quality, ultra precision metal mirrors have many other positive properties. Most important are high precision positioning features that are well aligned to the optical coordinate system and that can be well integrated into the mirror’s structure. Light weight mirrors with on axis or off axis geometries and even freeform surfaces are efficiently produced at son-x.

One of our unique features is the possibility to manufacture precision mirrors from single millimetre up to 1000 mm in diameter. Any size can be produced from single piece to large quantity for a competitive price. Contact us to get more information for your application.

Mould Inserts

Direct cutting of hardened stainless steel with single crystal diamond tool was not possible for a long time due to high tool. Since 2011 son-x has commercialized the unique ultrasonic assisted diamond turning technique that does allow ultra precision machining of steel without nickel plating. We produce best in class optical mould inserts directly cut into stainless steel for automotive lighting, imaging, ophthalmic or other injection moulding applications.

Plastic Lenses

The development of optical systems often requires practical testing of the theoretical optical components. Son-x offers quick turnaround for high quality prototype plastic lenses based on 3D/2D data. Once the optical system has been refined and confirmed by the prototype, we can scale the quantity into high volume.

Infrared Lenses

Demanding applications such as defense require ultra high precision optics made of crystal materials like Silicon, Germanium or Zinc-Sulfide, among others. Son-x delivers these diamond turned optics in a variety of geometries ranging from apsheres, diffractives, freeforms and lens arrays. We guarantee maximum confidentiality and 100% made in Germany.
