A near-infrared 0.8-2.5 micron imaging camera for use at the f/8.75 Cassegrain focus of the Palomar 60-inch telescope is described. The simple and economical design of this camera is readily adaptable to other telescopes. It features diffraction-limited reimaging optics, high optical throughput (39% at H), and effective K-band background suppression. The camera utilizes an all-reflective, all-spherical optical design that is a variant of the Offner 1:1 reimager. The readout electronics are straightforward, reliable and have low noise, while the data acquisition system is robust in its utilization of a real-time UNIX operating system on a PC. The electronics and data acquisition system are described in detail. Various aspects of the performance are given, along with initial results which show that the performance goals ofthe camera are now fully realized.
