Nitrogen cleans eyepieces
Gas for Zeiss quality
The name Zeiss has been synonymous with optical devices of the highest quality for more than 150 years. Since last year, Carl Zeiss SportsOptics GmbH in Wetzlar has been using nitrogen from Messer to clean its high-quality eyepieces for binoculars. Thanks to its high purity and complete dryness, gaseous nitrogen cleans the eyepieces more effectively than compressed air. Binoculars are also fi lled with nitrogen to prevent misting as a result of moisture. The company uses over one million cubic metres of nitrogen for this every year. A twelvemetre-high nitrogen tank, which can be seen from afar, has therefore been installed on site at the optical specialist’s Hesse plant.
