Acktar™ specializes in ultra-black, light absorbing coatings and foils, which are qualified for space and in use in numerous satellite-borne instruments. Main application fields are straylight suppression, laser power absorption and high-emissivity coatings in the field of photonics.

Acktar's inorganic coatings are fabricated using Acktar proprietary vacuum deposition technology. A high specific surface area coating is created with a tightly controlled morphology to produce a low reflectance level.

The coating thickness is a few microns (typically 3-5 μm) and its density is typically ~1.8 g/cm³. The deposition process is carried out at wide range of temperatures depending on the substrate.

By controlling the composition and morphology of the layer microstructure, it can be tailored to achieve desired levels of absorption or reflectance over a wide range of wavelengths (EUV-UV, VIS, NIR-FIR). The deep black foils and coatings can be applied to almost any surface (metal, glass, silicon, ceramic, plastic) - for example for stray light optimization, laser absorption, improvement of signal-to-noise ratio (SNR) and high-emissivity coating in technical optics.
