Caption

This is a cut-away view of the Mars Surveyor 98 Orbiter Color Imager's "Medium Angle" camera. This camera has a mass of 510 gm, draws 2 W when operating and 0.1 W in standby mode. It has a field of view of 6 degrees. The cut-away drawing shows the six lenses and two mirrored surfaces (the pictures shows the primary mirror in front of the electronics boards) of the f/2, 87.9 mm focal length, catadioptric lens. Behind the lens are two, 2-sided electronics boards. The board immediately behind the lens is the Focal Plane Assembly (FPA), which includes the megapixel charge-coupled device (CCD) imaging sensor and support electronics. The second board is the Data Acquisition System (DAS), which includes a high-speed (60 MHz) digital signal processor (DSP) and other advanced electronics parts.

From 400 km altitude, this camera will image a swath 40 km wide at a resolution of 40 m per pixel. Between the last lens and the CCD is a 10-color filter that permits multi-color observations for composition mapping, and to distinguish different types of clouds on the basis of color.

Shown for scale is the reverse side of the "advanced technology" Susan B. Anthony dollar--the power (?) of a dollar in the size of a quarter ;^).

The image should be adjusted for brightness according to your monitor. The boards are a medium bright green.

The image is a computer rendering of the camera made by Malin Space Science Systems software engineer Jeff Warren.
