In a sight device, an objective lens unit is disposed at an end of a housing. An ocular lens unit is disposed at another end of the housing and opposite to the objective lens unit. An erector unit is disposed between the objective lens unit and the ocular lens unit. A adjusting unit is movably disposed on the housing and radially propped against the erector unit to adjust the erector unit. A light emitting unit is disposed on the erector unit and includes a light source for emitting a light beam to an object. A light receiving unit is disposed on the erector unit and includes a light sensor for receiving the light beam reflected by the object. In any cross section of the housing, any point on the external surface of the housing is approximately equally distant from the second central axis.

Sight device

A compensating mechanism includes a base, an adjusting unit, an adjusting cover and a stop unit. The adjusting unit is disposed in the base. The adjusting cover connects to the adjusting unit and includes a curved groove. The stop unit is disposed between the adjusting unit and the base and includes a pin. When the adjusting cover is rotated, the adjusting unit is only rotated with respect to the base and the stop unit is axially moved with respect to the base so that the pin enters or leaves the curved groove.
