Buying Black Coatings
Black coatings exhibit strong absorbance for a wide range of incidence angles. They are primarily used to suppress stray light in optical systems but also find applications in thermal management due to their high emissivity.

 We like it black ACM Coatings GmbH (subsidiary of Acktar Ltd.)Jakobsring 3 06618 Naumburg (Saale) Germany See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 4639)! |  AcktarBlack™ Direct Coating Services suppress stray light in high-performance optics with no extra effort using advanced optical black coatings for stray light absorption in ultra-violet, visible light spectrum and infrared wavelengths. Extremely low reflectance, high thermal stability, high absorptance, high emissivity, excellent adhesion to essentially all materials and low outgassing in a few microns of a coating. You say when, and we coat it for you! AcktarBlack™ coatings are available not only for direct application to parts, but also as coated foil or film. The coated foils enable the customer to benefit from Acktar coatings performance without sending the parts to Acktar. This is an ideal solution for very large quantities, over-sized part areas and for contaminated environments where the light absorbing surface needs to be periodically renewed. The black foil coating are available with or without an adhesive backing as sheets, die-cuts or roll. |
