Multilayer 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. Ultiquest Tech can provide such coating with center wavelength from 250nm to 2200nm. When selecting a suitable multilayer antireflective coating,the center wavelength and damage threshold must be considered.

For your application,please refer to its following characteristics:

 Multi-layer AR can reduce the remaining reflectance to less than half of a single layer AR. 
 Essentially the effective wavelength range is narrow, but it could be broaden by choosing appropriate deposition material, number of layers and their thickness.
