ガラス。 One of its surfaces serves as a reflecting surface for reflecting part of the light incident on that surface with a reflection angle corresponding to the incident angle, and the other surface reflects the other part of the incident light from that surface. A polishing process for achieving the required flatness of one surface of a thin plate glass material that is to be used as a reflective surface, which is a thin plate glass that is used as a transmitting surface for transmitting and emitting light. 1. A thin plate glass characterized in that the polishing process is not applied to the other surface that should be the transmitting surface.
