Mastcam narrowband filters. (a) Photograph of white light transmitted through the Mastcam‐34 (Mastcam‐Left) filter wheel. Labels indicate the filter positions, left zero through seven (L0–L7), and effective center wavelength as determined by Bell et al. [2017]. (b) Photograph of white light transmitted through the Mastcam‐100 (Mastcam‐Right) filter wheel. Labels indicate the filter positions, right zero through seven (R0–R7), and effective center wavelength as determined by Bell et al. [2017]. Filter aperture diameters are 12.6 mm diameter. (c) Mastcam narrowband filter transmissions and CCD Bayer pattern filter (BPF) response functions. Note that the three BPF dashed lines extend longward of 700 nm wavelength, indicating leakage, and that they converge longward of 850 nm, meaning that they are equally transmissive at longer wavelengths, which permits imaging at these scientifically interesting wavelengths.
