Optical coating materials
Patinal® evaporation materials have been designed to meet the specific requirements of optical thin film production using physical vapor deposition (PVD). Our portfolio comprises more than 40 evaporation materials including fluorides, oxides, sulfides, and metals – all offering outstanding quality and reliability. Depending on your requirements and productivity demands, we can provide you with granules, tablets, or discs. Our suboxides help reduce melt preparation times, and our special oxide mixtures allow you to adapt film stress and achieve the right deposition on plastic substrates. For reduced processing times, we also offer high-density oxide mixtures.
All of our Patinal® materials are manufactured and tested according to the highest quality and processing standards. They also have a proven track record when it comes to high performance in optics manufacturing. Due to their high purity, low spitting levels, and tried-and-tested process stability, Patinal® evaporation materials enable optical coatings with high durability – even in the most challenging applications such as laser systems or optics used in harsh environments.

Quality assurance
Like for all our products, the quality of every batch of Patinal® products is tested. This includes application testing to safeguard high and reliable batch-to-batch reproducibility and ensure materials performance in accordance with uniform standards for each coating process. Our quality controls are performed in compliance with all prevailing standards and regulations. Aside from material safety data sheets, we also provide certificates of analysis for all batches through our website.
