High Reflector Coating HR
Description
High-reflection (HR) coatings work the opposite way to antireflection coatings. The general concept is usually based on the periodic layer system composed from two materials, one a high index and the other a low index material. This periodic system significantly enhances the reflectivity of the surface in the certain wavelength range called band-stop, whose width is determined by the ratio of the two indices (for quarter-wave system), while the maximum reflectivity is increasing nearly up to 100% with a number of layers in the stack.

Frequently Asked Questions
The purpose of a high-reflection (HR) coating is to significantly enhance the reflectivity of the surface in a certain wavelength range.
High-reflection (HR) coatings work by using a periodic layer system composed of two materials with different indices of refraction. This system enhances the reflectivity of the surface in a specific wavelength range.
The maximum reflectivity that can be achieved with a high-reflection (HR) coating is nearly up to 100% with a number of layers in the stack.
The width of the wavelength range in which a high-reflection (HR) coating works is determined by the ratio of the indices of refraction of the two materials in the periodic layer system.
Yes, the high-reflection (HR) coating is suitable for laser applications as it is referred to as "High Reflective Coating (Laser Quality)" in the product description.
