We are Focal
Focal vision & optics is the integration and development partner in the fields of Industrial Precision Inspection, Medical Optical Systems and Hightech Optical Systems. Focal develops and realizes precision inspection and optical measurement systems for customers in automotive, life sciences and semicon.
Focal performs custom design and engineering (D&E) in a multidisciplinary approach, consisting of optical engineering, machine vision and system engineering. Activities include high-level requirements engineering, concept optical design, prototyping, detailed engineering, system integration and delivery.
The result of our efforts is systems that work, which are either integrated and supported in the customers’ production lines, or delivered as modules ready for integration in high-tech or medical OEM products. Increase quality and productivity with automatic optical inspection systems from Focal.
As camera frame rates increase, true real-time vision controlled systems will become cost-effectively available. Visual inspection loops of 2D image computing at 1,000Hz will be reality. We design and implement FPGA-based vision-in-the-loop solutions for real-time, precision quality inspection in a control & feedback loop
Hyperspectral imaging systems
Design and delivering fingerprint specific hyper- and multispectral imaging applications for measurements or inspection tasks. We enable real-time spectral-spatial decision-making by using the latest camera technology with CMOS-deposited filters.
Freeform optical components
Finally cost-effective aspheres, rotational invariant discontinuous surfaces, structured surfaces, arrays of lenses or pyramids can be introduced in optical systems since modelling, manufacturing and measuring freeform optics is maturing. This allows focal engineers more design freedom in the areas like semiconductor development, consumer electronics (HMD, mobile phone cameras, etc.), general lighting and automotive applications (LED) and medical e.g. personalized ophthalmology.
We provide the optics for delivering, separating and measuring the excitation and (weak) emission signals. Combined with our know-how of miniature microscopes with high NA objectives we design and engineer compact solutions for demanding environments.
Low coherence interferometry
Surface measurements in sub-mm and sub-μ range for complex shape inspection tasks in industrial environment and medical domain. Focal has realized different interferometry layouts such as Michelson and Linnik. Technology is to be applied in height profile of MEMS chip structures, fiber facet quality inspection and full-field OCT measurements.
HOW WE WORK
Although there are different approaches for turnkey vision systems and OEM-modules, we roughly take a similar staged approach:
This phase is all about understanding your needs. You’ve found us. Maybe you’ve already sent us a brief description with images attached to explain your need in more detail. We will contact you, we will visit you and collect samples of items that are to be automatically inspected or measured. Maybe you have solution ideas that you like to discuss or evaluate. A first assessment will be done, providing you with an outlook of a future project.
Several technical solutions and options will be evaluated, based on a more thorough insight after the intake and possibly more samples which you have given us. In cases that requirements cannot fully be defined (made SMART), the feasibility phase will be used to identify the inspection or measurement requirements. Suggested solutions for the concept design, including budget estimates, will emerge from this phase. For OEM modules we provide an overview and trade-off of concept solutions and expected performance.
In this stage you have given the ‘’Go’’ for detailed design and engineering work and we will define, purchase and have produced the components that will constitute the optical inspection module. We will choose and implement the most rigid optical imaging, illumination and vision algorithm strategy and work towards an integrated module. Your use case or user flow definitions will be implemented. For OEM manufacturers we provide detailed design and test documentation accompanied with a performance analysis.
In this stage we will integrate the vision module in your production environment. Establish connections with any mechanisation or mechatronics present, and interface with quality or monitoring systems in your facilities. For OEM-customers we will perform the qualification of the module and provide the means for integration of the OEM-module in your product.
