This, report deals with the evaluation of a large format image tube camera of a type under consideration for use on the Space Shuttle Sortie Missions. Our evaluation covers the following subjectsn1. resolving power of the systemn2. geometrical characteristics of the system (distortion etc.)n3. shear characteristics of the fib-r optic couplingn4. background effects in the tuben5. uniformity of response of the tube (as a function of wavelength)n6. detective quantum efficiency (DQE) of the systemn7. astronomical applications of the system
