Tunable etalons and other applications of multi-application low-voltage piezoelectric instrument control electronics (MALICE)
EMS have developed low voltage piezoelectric (LVPZT) tunable filters for the James Webb Space Telescope (JWST), and a wide field tunable Michelson for the Canadian Space Agency"s (CSA) Stratosphe...
Optical design for a Fabry-Perot image interferometer for solar observations
We outline here a preliminary optical design study for a telecentric tunable Fabry-Perot etalon system. The first result of the optical optimization into a design, which delivers performance image qua...

HAWK-I(High Acuity, Wide field K-band Imaging) is a 0.9 µm- 2.5 µm wide field near infrared imager designed tosample the best images delivered over a large field of7.5 arcmin x 7.5 arcmin. HAWK-I is a cryogenic instrumentto be installed on one of the Very Large TelescopeNasmyth foci. It employs a catadioptric design and the focalplane is equipped with a mosaic of four HAWAII 2RG arrays. Two filter wheels allow to insert broad bandand narrow band filters. The instrument is designed to remaincompatible with an adaptive secondary system under study for theVLT.
