Multilayer Antireflective Coating

These multilayer antireflective coatings can reach the lowest reflectivity at center wavelength. It is often applied to a single laser wavelength or multiple, closed-space wavelength system to guarantee the lowest loss at center wavelength. Sinoceramics can provide such coating with center wavelength from 250nm to 2200nm. When selecting a suitable multilayer antireflection coating, the center wavelength and damage threshold must be considered.
