K-Cam III on Lick 1-m

K-Cam III


Kcam III is a near infrared camera system dedicated to the astronomical "K" band from 2.0 to 2.4 microns. The detector in this camera is the NICMOS3 mercury-cadmium-telluride (HgCdTe) array from Rockwell International Science Center (Thousand Oaks, Ca.) which has 256 x 256 pixels each 40 microns square. Originally commissioned on the University of California Observatories (UCO) 1-m Nickel Telescope on Mt. Hamilton, KCam III is now used exclusively on our 24-inch telescope on the UCLA campus together with a Photometrics Star 1 camera system (with BVRI filters) and a dichroic beamsplitter to enable optical and IR bands to be observed simultaneously. The image scale is 0.85 arcseconds/pixel. First Light was obtained in March 1992. Current applications include the following: student teaching projects, monitoring variable stars, monitoring the optical/IR variations of active galaxies, photometry of T Tauri stars too bright for larger telescopes, observations of Io during eclipses by Jupiter's shadow.
