Published on 2010-06-11. Author : SpecialChem

With its new CrBlack™ coating, Optics Balzers offers a solution for reducing light scattering. Optics Balzers has succeeded in utilizing the black chromium properties, to date applied predominantly in solar collectors and sunglasses, and adapting them to additional uses in medical devices and industry.

The CrBlack™ black chromium coating is an optically black coating distinguished by its high absorption capacity and its minimized reflection in the VIS range. Its color hue can be tailored to customers' specific requirements, for example to produce a black chromium part with a blue component. Thanks to its high reduction of scattered light and an ROHS-conform coating, CrBlack™ is excellently suited to applications in lens systems of medical devices.

The high adhesion of the coating on glass and metal in conjunction with its high application temperature of up to 250°C allow uses in a wide variety of fields. The CoatingPlus capabilities of Optics Balzers also enable CrBlack™ to be patterned for demanding applications.

The CrBlack™ black chromium of Optics Balzers is characterized by its high environmental stability and durability. The whole-surface or patterned coating can be easily cleaned following additional process steps.
