Optical device

摘要

An optical device has a tube including a tube wall defining a viewing bore. A light source is in communication with the viewing bore for illuminating an aim point visible in the viewing bore. A control system includes a circuit board supported by the tube exterior of the viewing bore. The control system is in communication with the light source for controlling brightness of the illuminated aim point. The control system includes a light sensor mounted to the circuit board and extending from the circuit board through the tube wall into the viewing bore for sensing light in the viewing bore.
