A perfect mirror (or perfect reflector) is a specialized mirror which reflects electromagnetic radiation perfectly without absorbing or distorting the wave. Near-perfect mirrors have been achieved by stacking thin dielectric material . Dielectric-coated mirrors have been able to reflect 99.9999% of light, but are limited to reflecting specific wavelengths of light at pre-determined angles of incidence.[1]MIT researchers were able to create the first perfect mirror by confining light with a patterned dielectric slab.[2] Applications of perfect (or near-perfect) mirrors include advancements in solar energy with improvements of solar cells, lasers, and discovering gravitation waves at LIGO, KARGA, and VIRGO.[3][4]
