Abstract

A calibration device to calibrate precise horizontality of a light emitting element includes a retaining rack, a microprocessor, a regulating member, two driven members, and two photo sensing members. The regulating member drives the light emitting element, the two driven members are on the retaining rack, and the microprocessor controls the driven members to move linearly. The photo sensing members detect light transmitted and data as to the vertical distance between two driven members, and vertical distance between the photo sensing member and the two driven members, is stored. The microprocessor calculates the moving distance of the photo sensing members carried by the driven members based on the signals of light detected, and further calculates declination of the light emitting element. The microprocessor can adjust the orientation of light emitting element.
