| DESCRIPTION |
The Mariner 6 Spacecraft Wide Angle Camera (WAC) had Zeiss refractor optics with a shutter that incorporated four spectral filters in a rotary wheel in the order red, green, blue and green again. The wide angle f/5.6 lens had a focal length of about 52.5 mm. The optics focused images onto a vidicon to obtain images of Mars. The vidicon was etched with a 7 x 9 grid of reseaux to aid in computing the geometric distortions in the digital images. The WAC produced 945 sample by 704 line, 8 bit/pixel digital images after ground processing.
