IRCAL pictures

The IRCAL Dewar

IRCAL is an infrared camera for use with the LLNL AO system at Lick observatory 3-m.

The optical bench (anodized black) can be seen running from bottom left to top right. The dewar window is on the right, the PICNIC 256x256 detector head is at the lower left. The outer dimensions are 12" x 18". This picture shows the double floating radiation shields which give a hold time of 72 hours.
