Sill Optics is one of a few medium-sized companies in Germany, which has specialized in production of optical components of highest quality. Its philosophy: “100% Made in Germany”. Best quality manufactured in-house. Since its foundation in 1894 enormous technical skills, extensive knowledge of manufacturing, as well as significant production flexibility has been established.
Furthermore Sill continuously invests in latest production technology, within the last ten years more than 10 million Euro in recent machinery and testing technology. The production includes a wide range of lenses and complete systems for the following branches: Laser and photonics, machine vision and optical measurement, illumination, and medical technology. We supply our customers from the development of a specification to the final series product. All design and production steps are realized in-house, even for small series or prototypes only.
F-Theta lenses for large scanner apertures
With ongoing improvements in the development of laser systems, laser intensities are still increasing with the goal of enabling faster processing speed. This progress does result in ever increasing requirements for lenses. In order to minimize the chance of damage and reducing thermal effects, increasing the initial beam size is a solid option. Thus scanner systems with large mirrors experience a rising demand.
F-theta lens with short focal length
The S4LFT4010/328, designed for 1030 – 1090 nm provides spot sizes of around 20 µm. The newest series of scan lens, S4LFT4065/328 with a focal length of 65 mm, is capable of accepting a 10 mm beam, generating a diffraction limited spot of around 10 µm on a 15 mm x 15 mm field. The S4LFT4065/328 incorporates fused silica lenses and our industry proven low absorption coating. Of course, there are no internal ghosts in lens elements or on scan mirrors.
