Paper Abstract

The Daniel K. Inouye Solar Telescope (DKIST) is a 4-meter aperture, off-axis, Gregorian configuration, solar telescope currently under construction on the top of Haleakela on the island of Maui, Hawaii1. When completed, DKIST will be the world’s largest solar telescope.

The optical performance of the telescope will depend on the accurate alignment of its mirrors. During Integration Testing and Commissioning (IT&C), mirrors will be installed and aligned sequentially. The alignment will be verified by measuring the wavefront progressively at different focus locations using starlight at night with a custom-designed wavefront measurement system (WMS) that consists of a Shack-Hartmann wavefront sensor. In this paper, we will present the optical design of the WMS. We will discuss the testing and calibration process of the as-built WMS in the lab and demonstrate the final in-lab performance.
