CrBlack™ Coating for Efficient Scattered Light Elimination

In almost any demanding optical setup minimum scattered light is required for each part of the optical setup, like e.g. for pinholes, apertures for lenses or filter arrays or cover lids. Materion Balzers Optics’ CrBlack™ is the ideal solution for this purpose. CrBlack™ is an optical black coating, characterized by high absorption and low reflection in the VIS and near IR range. This product is manufactured in the clean room to achieve a minimum defect/pinhole level. CrBlack™ can also be (micro)patterned by lift-off techniques and the color impression and optical density can be adjusted to the specific customer request.
