Components of L'LORRI

Components of L'LORRI
Lucy's camera is named L'LORRI (Lucy Long Range Reconnaissance Imager) and is almost identical in construction to the LORRI camera flown on NASA’s New Horizons mission to Pluto and its moons. The mirror for collecting the little sunlight reflected by the Trojan asteroids has a diameter of 20.8 centimetres and the focal length is 262 centimetres. This can be used to resolve a crater 70 metres in diameter from 1000 kilometres away (or, as the designers from the Applied Physics Laboratory at Johns Hopkins University wrote, "identify a fly on the goal beam from the opposite end of the field").
