Description
This signal mirror is designed for use in heliography, a method of communicating using sunlight. The mirror is made of polished metal and is concave so that it can concentrate the sun's rays. The edges of the mirror are beveled to create a sharp image. The back of the mirror is painted white to reflect light and help create a bright signal. The handle is made of wood and is adjustable so that the mirror can be tilted to the desired angle. This mirror is lightweight and portable, making it ideal for use in emergency situations.
