Wide Angle Camera (WAC)

March 4, 2009

Here is a picture of the LROC Wide Angle Camera (WAC) from last year, prior to its installation on the LRO spacecraft.  The silver vertical tube in the center with the small baffle above it is the ultraviolet part of the optical system. The large V-shaped baffle directly behind it is the visible part of the optical system. Both optics lead to the CCD sensor, which is located inside the electronics box on the bottom of WAC (where data and power cables are attached). The CCD is cooled by the comparatively giant radiator that is visible in the back of the image. For scale, the width of the electronics box is about 4 inches (10 centimeters).
