• :The cold box which contains : aperture stops, field stops, field lens that images the aperture stop on the cube corners, dichroic plates dividing the whole spectrum range into the three spectral bands, lenses which produce an image of the field stop onto the detection unit, three focal planes that are equipped with micro lenses.
