We offer laser lighting and monitoring solutions for several applications in various industries.
CAVILUX laser illumination is a high-performance tool for various applications in scientific and industrial research and development.
Fiber coupled laser illumination solutions for real-time image analysis to improve process control and to measure what happens inside the tanks, reactors or pipes.
Accurate, intense and powerful laser illumination for paper and pulp industry. Obtain important information from many different stages of the process: of fibers, flocks and consistency of the medium, pulp distripution on a web, surface topography, homogeneity of the paper web as well as the line condition.
Defense industry typically involves applications having targets that are extremely fast and small which require very accurate and fast monitoring methods.
Laser illumination for clear visualization of welding process without process emitting brightness for industrial monitoring, process control and quality improvement.
See through heat. Foundry processes and metal manufacturing in general can benefit from laser illumination in various process stages. E.g. precise online-monitoring of slab surfaces in continuous casting process, monitoring of the condition of protective layers of furnaces and ladles.
Along with welcoming the VISION 2018 fair, that took place in Stuttgart beginning of November, we welcomed our distributors to get an update on our current developments as well as on our latest applications and products.
