sentences:  The set of filters consisted of a broad-band filter with a bandpass of 400 to 800 nm, four narrow-band filters with center wavelengths (and bandpass width (FWHM)) of 415 nm (40 nm), 560 nm (10 nm), 650 nm (10 nm), and 750 nm (20 nm), and 1 opaque cover to protect the image intensifier.The field of view was 0.3 x 0.4 degrees, translating to a width of about 2 km at a nominal lunar altitude of 400 km.The image array is 288 × 384 pixels, (pixel size of 23 × 23 micrometers) so the pixel resolution at the Moon was 7–20 m depending on the spacecraft altitude.
