In-house Production

Our company currently employs 200 people, where 135 (including 15 apprentices) of them work in the precision production for lenses, mounts and the assembly. 50% of these employees are skilled personnel, such as fine opticians, fine mechanics or instrument mechanics. A 100% inspection by qualified personnel guarantees the quality of our lenses after production, coating and assembly.

Latest CNC machines are available for pre- and fine-grinding, polishing and centering of our optical components, as well as for turning and milling of the mechanical parts. 1400 precision lenses with various diameters from 4 mm up to 300 mm are produced daily. Further capacities for illumination lenses with diameters up to 650 mm are available. Special material with sizes up to 1.5 m can be handled with optical quality as well.

Development and design

Sill Optics has its own optical development department working with latest optical design software “Zemax” and mechanical construction software “Solid Works”. This enables the design of optical and mechanical components optimized for the application of our customers.
