SED Machine Lens Design

This is a multipart post on the SED Machine lens design. In this post I will describe the front end of the SED Machine.

Palomar 60-inch Telescope

The Palomar 60 inch was built in the 1960s (Bowen & Rule 1962) to study objects that did not warrant time on the Big Eye of the 200 inch. Built when photographic emulsion was our most sensitive detector, the telescope has a short back-focal distance of about five inches.

Automated in 2006 by a team of GRB hunters the robotic 60-inch telescope serves as the basic platform for the SED Machine.
