Dielectric HR Mirror,Optical High Reflection Mirror optical mirror
High-reflection (HR) Dielectric Mirror refer to coating layers of dielectric films on optical substrates, and are
designed to achieve the highest possible reflectance, usually at specific wavelengths. Although engineered
for best performance at normal (0) or 45 degrees angles-of-incidence, these coatings can be tailored for
most any angle. Specially Dielectric HR Mirrors are suitable for the application of laser resonator cavity and
return of light path.
