INNOVATION AND DEVELOPMENT – WE LOVE IT.
Designing and manufacturing optical thin film filters is more complex than one might think. To achieve the first part of our vision
"Striving to improve the quality of life, we serve our OEM clients with innovative optical filters. The brightest talents find the opportunity to set new standards in our company and industry by bringing advanced optics into people's everyday life"
we have established a fine-tuned process chain from front to end: from the first idea for a filter to the finished product. The chain involves the first draft specifications, discussion of the intended application, modification of the specifications to increase yield and reduce cost, filter design and coding of the deposition control strategy, purchase of fresh substrates, design and manufacture of tooling if needed, incoming inspection and cleaning of the substrates, prototype production for more complex filters, up to five coating runs with intermediate spectral control and cleaning, dicing to the final size, final spectral and visual control including documentation, and last not least packaging and shipment. Click on the hot spots in the illustration below and learn more about the process steps and the interaction between you, our sales, development and production departments that finally lead from your idea to the filter you need.
