Precision Mold Making for Optical Parts

We are focusing on Optical Mold making with high quality diamond turning, SPI A1 polishing with PC and PMMA transparent material for more than 15 years in Optoelectronics,consumer electronics ; automotive, lighting, telecommunications, Monitoring and military sectors.

Each optical component is only as good as the appropriate tool. Accurate technical preparation and constant control of the tolerance limits are the success factors for a consistently high quality in series production – even with large production volumes.

The GPT Optics has its own high-precision tool with many years of experience and advanced machinery. In this way we ensure a consistently high quality in mass production.

The optical inserts are manufactured with a multi-axis diamond turning machine with air bearing guides and spindles. Form accuracies of up to +/- 2-3 μ (depending on diameter and optical requirements) and surface roughness less than 5 nm are possible.

The fast/ slow tooling, an ultra-precise extra unit, enabling the creation of microstructures and non-rotationally symmetric operations. These inserts are for example needed for producing free-form surfaces or aspheric.

During prototyping, the high-precision tools are first time in use. Prototypes or small batches can be produced by injection moulding with trial and pre-series.
