Next-generation infrared astronomical instrumentation for ground-based and space telescopes requires MOEMS-based programmable slit masks for multi-object spectroscopy. We made a full space evaluation of Texas Instruments DMD chips, including tests at cold temperature and in vacuum, life tests, radiations, and vibrations and shocks. These results do not reveal any show-stopper concerning its ability...
Next-generation infrared astronomical instrumentation for telescopes requires MOEMS-based programmable slit masks for multi-object spectroscopy. A large micromirror array of 20'000 micromirrors has been fabricated for cryogenic environment utilizing a dedicated assembly stage. Preliminary tests demonstrate the functionality of both the assembly system and the device.
Next-generation infra-red astronomical instrumentation for space and ground-based telescopes requires MOEMS-based programmable slit masks for multi-object spectroscopy (MOS) usable in a cryogenic environment. A 100x200 mum2 micro-mirror array was successfully designed, fabricated and tested, with tilting angle of 20deg at 100 V. In parallel we have developed and implemented a high-resolution Twyman-Green...
