Suppress Stray Light with Acktar® Ultra-Black Coatings – Now In Stock at Edmund Optics

Edmund Optics stocks a comprehensive selection of Acktar^®’s ultra-black light-absorbing products, engineered for advanced optical systems that demand maximum stray light control. Featuring proprietary coatings like Metal Velvet™ and Spectral Black™, Acktar’s foils and components offer total hemispherical reflectance as low as ~1% across the visible (VIS), short-wave infrared (SWIR), and long-wave infrared (LWIR) ranges.

Unlike traditional black paints or carbon nanotube coatings, Acktar^® products are dry, non-particulate, cleanroom and vacuum compatible, with no outgassing or curing. Their peel-and-stick application supports easy integration onto curved, irregular, or compact surfaces.

Edmund Optics offers an extensive range of Acktar^® light-absorbing products off the shelf, including foils, films, panels, laser beam traps, pinholes, air slits, and C-Mount noise-reduction tubes—ideal for imaging, IR, and laser systems. Sizes range from 1" die-cuts to 50-meter rolls, offering unmatched flexibility for both prototyping and production.

With the industry’s widest selection of off-the-shelf Acktar^® foils, off-the-shelf availability, and global fulfilment, Edmund Optics provides a convenient one-stop shop for blackening products and beyond.
