Fig. 5From: In situ science on Phobos with the Raman spectrometer for MMX (RAX): preliminary design and feasibility of Raman measurementsBBM of RAX. a Entire breadboard. b Focusing unit. c Schematic diagram of BBM (see also Rodd-Routley et al. 2021). Actuator rotations are converted to vertical motion with a lead screw and linear guide. The actuator and linear guide are the COTS components used for the RAX flight model after screening. Mass of the lens is comparable to the flight lens barrelBack to article page
