Abstract
CMB-S4, the next-generation CMB observatory will deploy hundreds of thousands of detectors to enable mapping the millimeter-wavelength sky with unprecedented speed. The large-aperture telescopes for CMB-S4 consist of six-meter diameter crossed Dragone designs to be deployed in Chile and an innovative five-meter diameter three-mirror anastigmat to be deployed in the South Pole. The two-mirror crossed Dragone requires instrument corrections as demonstrated earlier in these proceedings. We discuss biconic lens corrections for the CMB-S4 crossed Dragone telescope camera optics and we give an overview of the camera optics for the three mirror anastigmat as the optical designs of the cameras for these telescopes are prepared for manufacture.

I am a fellow at the Kavli Institute for Cosmological Physics at The University of Chicago. I work on optical design and optical modeling of millimeter-wave instruments that observe the cosmic microwave background radiation (CMB), the oldest light in the universe. In addition, I work cross-correlating catalogs of galaxies with maps of the CMB to measure the motions of galaxy clusters at distances of tens to a few hundred megaparsecs. I obtained my Ph.D. in Physics from Cornell University and graduated from electrical engineering at Universidad Católica de Chile in Santiago.
