An antireflective or anti-reflection (AR) coating is a type of optical coating applied to the surface of  lenses and other optical elements to reduce reflection.
Such antireflective coatings can reaches the lowest reflectivity at a center wavelength. It is often applied to single laser wavelength or multiple, closely-spaced wavelength system to guarantee the lowest loss for center wavelength. We provides such coating with center wavelength from 250nm to 2200nm. When selecting a suitable multilayer antireflective coating, the center wavelength and damage threshold must be paid attention to.
