MULTILAYER REAR-VIEW MIRROR FOR MOTOR TRANSPORT Russian patent published in 1999 - IPC

FIELD: motor transport. SUBSTANCE: device has reflecting substrate, multilayer coating, and reflecting metallic layer which is deposited on multilayer coating. Multilayer coating has at least one layer of material with high refraction index which is deposited on substrate surface, and at least one layer with low refraction index. Said high refraction index layer is made from semiconductor material with refraction index of 3.4-3.8, for example, amorphous silicon, or amorphous hydrogenated silicon, or amorphous silicon-germanium alloy, or amorphous hydrogenated silicon-germanium alloy. EFFECT: increased relative visibility at night, increased efficiency of suppression of spotlight from rear cars. 8 dwg
