Abstract
An apparatus, which is for assisting in calibration of an optical axis of a light beam generated by a light emitter of an instrument, includes a body, a sensor module, and an indicator module. The instrument includes a sighting unit that has a specified position relationship with the light emitter. The body has a surface provided with a reference mark. The sensor module is mounted on the surface of the body, generates an output signal upon receipt of the light beam generated by the light emitter of the instrument, and has a reference position relationship with the reference mark. The reference position relationship corresponds to the specified position relationship between the sighting unit and the light emitter. The indicator module is associated operably with the sensor module, and indicates position of an incident light beam received by the sensor module.
