Fig. 34.

Images of the stray light acquired with the left Mastcam-Z with a collimated beam overfilling the entrance aperture at a $-{20}^{\circ }$ azimuth and $0^{\circ }$ elevation for three different zoom position. The 100 mm frame is taken with a 1 s integration time, while the 63 mm and 34 mm frames are taken with a 10 s integration time. We find a stronger contribution of the stray light at the 100 mm zoom position, which is largely diffuse, but changes orientation by the 63 mm focal length, and re-focuses to a lens-flare effect at 34 mm
