PG - 506-539 LID - 10.1002/2016EA000252 [doi] AB - The Mars Science Laboratory Mast camera and Descent Imager investigations were designed, built, and operated by Malin Space Science Systems of San Diego, CA. They share common electronics and focal plane designs but have different optics. There are two Mastcams of dissimilar focal length. The Mastcam-34 has an f/8, 34 mm focal length lens, and the M-100 an f/10, 100 mm focal length lens. The M-34 field of view is about 20 degrees x 15 degrees with an instantaneous field of view (IFOV) of 218 murad; the M-100 field of view (FOV) is 6.8 degrees x 5.1 degrees with an IFOV of 74 murad. The M-34 can focus from 0.5 m to infinity, and the M-100 from ~1.6 m to infinity. All three cameras can acquire color images through a Bayer color filter array, and the Mastcams can also acquire images through seven science filters. Images are
