Abstract
DIVA (deutsches interferometer fuer vielkanalphotometrie und astrometrie) is a project of a small satellite, aiming to measure positions, proper motions, parallaxes and spectra of several million stars. DIVA will carry two Fizea interferometers with a baseline of 100 mm using a novel telescope design. It consists of a Gregory configuration with high secondary magnification and a four-component field lens system at the intermediate focus. We present the optical layout which allows diffraction-limited imaging over a 0.5 degree of view in the wavelength range 400-1000 nm. Critical aspects of the design are discussed. The present status of the project is briefly outlined.
