Abstract
More and more complex telescopes and astronomical instruments require: (1) Mechanics with low diffusion/reflection properties in order to decrease the level of scattered light, especially for use in infrared. (2) Mirrors with high reflectivities, in order to improve the level of useful light and/or extend the useful spectrum, especially to the near UV(320 nm - 400 nm), SESO will present simultaneously here some results of its current developments concerning: (1) Solutions to increase the signal/noise ratio for systems operating in the infrared and needing a cryogenic cryostat assembly for the detection system, (2) A high efficiency reflective UV-coating.
