IR processes: SYRUSpro can achieve utmost uniformity
Alzenau, 02/2005
Optical coatings for infrared are needed for different applications such as infrared sensors, infrared detectors, infrared cameras, thermal control, night vision systems, high power IR lasers and many others. The demands on infrared processes are different from those at lower wavelengths. The most common dielectric materials which are used for VIS and NIR are not fit for far-IR.
The evaporation of common IR materials (like germanium) and different fluorides creates high demands on the coating system. LEYBOLD OPTICS' SYRUSpro is designed to meet all the requirements for these as well as for the delicate substrate materials. Common materials for FIR inevitably lead to a contamination of the coating chamber, which can spoil the optical performance of coating for VIS applications. Even if the substrate is extremely curved (up to a hemisphere shape) the SYRUSpro system can achieve utmost uniformity with our planetary substrate holder system.
For IR applications the durability specification is mostly just as important as the optical performance. By using the APS source for different materials, LEYBOLD OPTICS can reach higher packing density, higher durability and lowers absorption than with conventional coating only.
About LEYBOLD OPTICS
As a prominent manufacturer of vacuum coating systems and developer of processes for the thin film technology, LEYBOLD OPTICS is represented in thirteen countries worldwide. The main focus of our processing technologies is on evaporation, sputtering and plasma-assisted coating processes for display technology, ophthalmics, precision optics, reflective and protective coatings, web coating, R&D, and special applications.
The basis of our success was laid in Germany 150 years ago by Ernst Leybold and Wilhelm Carl Heraeus. They addressed their pioneering spirit to the search for new manufacturing processes and founded our internationally recognized vacuum-technology company, which has set market standards ever since.
