Metal optics made of Aluminium 6061 have been widely used to fulfill the demands of an athermal instrument design. Diamond turned metal mirrors are standard optical components in mid infrared astronomical instrumentations working at cryogenic temperatures. Structures and optics can be made from the same material (aluminium) to avoid thermal stress due to different CTEs. However, surface roughness, scattering beh
