Non-isothermal glass molding

Economically efficient production of illumination optics made of glass

The demand for complex and, at the same time affordable glass optics is growing in the lighting technology, automotive manufacturing and sensor systems sectors. However, the trend towards increasingly complex geometries and ever higher levels of precision accompanied by falling market prices is presenting companies with a range of challenges.

The Technology

Non-isothermal glass molding is a forming manufacturing process which enables glass parts to be produced in one single process step. In contrast to conventional grinding and polishing processes, the non-isothermal glass molding process is capable of producing complex glass optics and even micro-structured surfaces economically. The short process times coupled with the absence of any need for finishing operations mean that the process is ideally suited to mass production. This ensures that the advantages of glass as a material can be exploited for the application you have in mind.

Typical products


For the compensation of classical lens errors glass molding is the right way to manufacture cost efficient aspheres.

Free-form lenses

Molded free-form lenses and non-rotational symmetric optics are highly suitable for complex lighting and sensor applications.


Molding a variety of optics in one single step delivers higher quantities in shorter process time.

LED Optical Head

Using glass optics for LED enables lighting components with high power density and longer lifetimes.


By glass molding prisms with complex curved and flat surfaces can be produced in one component.

Fiber Optics

Highly precise light guides allow specific and homogeneous illumination.
