Paper Abstract

This paper gives an overview on the development of a light weighted Cassegrain telescope with a 200 mm optical aperture as one key element of the Laser Altimeter which will fly on the BepiColombo mission to Mercury (BELA).The Receiver Telescope (RTL) collects the light pulse transmitted to Mercury and reflected from the planet’s surface. Mercury’s challenging thermal environment, the thermo-mechanical stability of the telescope and the stringent instrument’s mass budget require the implementation of an innovative design solution to achieve the requested optical performance over an extended temperature range.
