The Giant Magellan Telescope (GMT) is one of the extremely large telescopes of the next generation. The GMT adaptive optics (AO) system uses an adaptive secondary mirror and natural and laser guide stars to achieve diffraction-limited images. The AO calibration source provides sources at the telescope prime focus which replicate the properties of the natural and laser guide stars, to calibrate and verify the performance of the AO system. We present an optical design for this calibration source, and discuss the expected accuracy based on the tolerance analysis.
