Cryogenic-fixation apparatus comprises a light source 15, a beam from which enters cooling liquid 6 in a cooling bath, 5 through a window 14 in the underside of the bath. The beam can be directed upwardly by means of a reflecting prism 22 (Fig. 3). When a lid 12' of the bath is closed, the beam leaves the space defined by the bath through an exit port 18 in the lid, and is incident upon a specimen 7 mounted on a specimen holder 8 located above the exit port, the specimen holder being secured to an injector rod 9. <IMAGE> |
