Double-beam photometer based on a monochromatic measurement of reflectance or transmission
Measuring technology for automated monitoring in optical production processes
We develop and manufacture devices for optical real-time monitoring. A system already in use for some time is fitted with a double-beam photometer based on a monochromatic measurement of reflectance or transmission. The optical monitoring systems can work on single or multiple wavelengths, automatically create projections and have a linear online trigger point correction. Monitoring results from film production programs can be transferred directly. The measuring devices are usually integrated into fully automatic operation, ensuring coating results that are stable and highly reproducible.
New optical technologies and products with new coatings also result in higher demands for the measuring technology used for monitoring. Real-time monitoring of the coating process is vital for achieving excellent precision and reproducibility. This gives a constant overview of the material deposition and makes it possible to work in an enclosed system with short cycle times.
