ANTI-REFLECTING COAT Russian patent published in 1996 - IPC

Abstract RU 2057351 C1

FIELD: optical instrumentation engineering. SUBSTANCE: anti-reflecting coat is composed of alternating layers, first and third ones of them have high refractive index, second and fourth layers have low refractive index. Optical thicknesses of layers counting from backing are tied up by relation as 10: 6: 4:1 and layer close to backing has optical thickness 0.163λ_o with n_h= 2.28-2.39; n_l=1.35-1.51; λ_o=0.6000 mm. EFFECT: enhanced optical characteristics. 1 dwg
