Ultra-black coatings are cleanroom- and vacuum-compatible
Acktar ultra-black, light-absorbing coatings offer total hemispherical reflectance as low as ~1% across the visible, shortwave-infrared (SWIR), and longwave-infrared (LWIR). Dry, non-particulate, and cleanroom- and vacuum-compatible, offerings include foils, films, laser beam traps, pinholes, and C-Mount noise-reduction tubes for imaging, IR, and laser systems. Sizes range from 1-in. die-cuts to 50-m rolls.
