Automobile rear view mirror comprises casing part inside and part outside vehicle having reflecting mirror and input and output lenses with diffractive surface displacing rays laterally

摘要

The rear view mirror comprises casing (1) which has part (1a) emerging inside the vehicle and part (1b) emerging outside the vehicle as well as reflecting mirror (2) in the bottom of casing. It comprises input convergent lens (13a) and output divergent lens (13b) in the inside and outside parts respectively. These lenses have diffractive surface which ensures lateral displacement of the rays.
