WE ENABLE BREAKTHROUGH APPLICATIONS BY COMBINING

PROPRIETARY COATING AND SOFTWARE TECHNOLOGY.

At Delta Optical Thin Film we do not rely on readily available software and hardware to achieve our goals. Through the years we have developed and optimised our own filter design software, software to design tooling for our coating chambers – especially for our unique continuously variable filters – and our own deposition control software to control our coating chambers. Furthermore, we have developed software to simulate the performance of the designed filters before they are produced, taking into account typical production tolerances.

We use SYRUSPro coating chambers from Bühler Leybold Optics equipped with their APS ion source and our own optical monitoring systems to produce custom optical filters. With the relocation into our new facilities we also deployed Bühler Leybold Optics' new Helios 800 magnetron sputtering technology. This allows us to economically produce the most demanding filter types such as multi-bandpass and notch filters.

To our knowledge we are the only company who was given access to the coating chambers' internal control software. This unique combination of world leading coating equipment with our own deposition control software enable the production of filters that continuously set new standards in the marketplace – all this combined with decades of experience to your benefit.
