摘要
The TolTEC camera is an imaging polarimeter installed at the Large Millimeter Telescope (LMT) in Mexico during December 2021. This new camera uses polarization-sensitive Kinetic Inductance Detectors (KIDs) coupled to the 50 m LMT to produce high resolution images simultaneously at 1.1, 1.4, and 2.0 mm wavelengths. We present a description of the cryogenic camera optics, the warm coupling optics, and the techniques used for on-site alignment of TolTEC with the telescope and characterization of the optics.
