optical system assembly.
Demcon focal manufactures optical systems in small volumes up to 50-100 per year. We can assemble laser modules, optical lens systems, microscope system and optomechatronic systems, such as the fine steering mirror.
Our facilities provide space for accurate and clean working. Our engineering-based processes enable flexibility and high levels of fine-tuning.

optical manufacturing.
Demcon focal has specialized tools for lens assembly construction and practical knowledge of adjustments and various curing methods. But next to necessary tools, creating state-of-the-art custom optics involves close collaboration between optical, opto-mechanical, and mechanical engineering disciplines to design a lens system that meets its requirements. Intimate knowledge of lens assembly equipment and its possibilities are needed to realize a prototype.
For various customers Demcon focal has assembled and aligned optics, such as:
- F-theta lens with a long working distance
- Focusing lens with a Strehl ratio > 0.95
- Lens systems for various microscopic applications
- Lenses for lighting applications
- Lithography lens with a distortion < 100 nm

optical qualification.
The proof of the pudding is in the eating. Key to optical performance is optical qualification. Demcon focal is experienced in optical qualification, and uses different state-of-the-art equipment and self-designed tools to deliver verified outputs. Since Demcon focal consists entirely of optical experts, we can be swift to detect and analyze production anomalies and revert to mitigations based on design knowledge.
