Patinal®

Patinal® stands for more than 30 years of production experience and excellence in evaporants for optical coatings. All this stems from centuries of specialist knowledge and analytical expertise.

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.
