ultracam requirements back to top

science the capability of taking short exposures (from milli-seconds to seconds) with negligible dead-time between exposures
design multi-channels (3 or more) covering a wide wavelength range in order to (minimally) distinguish a blackbody spectrum from a stellar spectrum
performance simultaneous measurement of the different wavelength bands to avoid problems of stochastic variations
performance imaging capability in order to simultaneously measure target, comparison stars and sky background and to avoid the need for fixed apertures
performance high efficiency and portability
