... All the optical elements are mounted in a cryostat aimed at keeping components at a temperature of about 80 K. The focal plane masks (field stops or slits) are mounted on a wheel. ... The collimator is an achromatic doublet lens, which images the entrance pupil of the TNG and provides an almost parallel beam (F-number about 2000) at the pupil plane, where Lyot stops can be placed. Right after the pupil plane, two close wheels mount filters and grisms. ...
