Optical mechanical theodolite
WebA theodolite is a precision optical instrument used to measure vertical and horizontal angles. It consists of a movable telescope that can rotate and pivot on the horizontal and vertical axes. Users sight multiple points through the telescope and take readings from the device to determine the angle (s) between the points.
