jsc2022e042616 (5/20/2022) --- The EMIT instrument before the enclosure panels were attached. The long tube in the foreground is the EMIT telescope baffle. The telescope resides in the large aluminum cube behind the baffle, and the spectrometer assembly is attached to the back of the telescope. The entire assembly is called the Optical Bench Assembly, or OBA. The OBA sits above the Electronics Mounting Plate, which is home to all of the instrument electronics and the cryocooler (not visible). Image courtesy of JPL.
