Zeiss compound Ultraphot 2 microscope, large laboratory model, 1950+
The Ultraphot was originally intended solely as a large format camera microscope the Photomicroscope was the concurrent Zeiss 35mm instrument but changes in photomicrographic practice later led to the development of a rather clumsy 35mm photohead for it This used a similar exposure control system to that of the Photomicroscope and boasted a clockwork motor wind In spite of a number of mostly small modifications the basic form of the instrument remained unaltered until its replacement around 1973 by the monolithic and relatively commercially unsuccessful Axiomat The most important change during its long lifetime appeared around 1970 when an entirely new automatic shutter mechanism incorporating a photomultiplier was fitted to both the 35mm and large format photoheads A larger base had to be designed in order to accommodate the extra circuitry and the finish was changed to two tone grey from the black and metallic grey typical of the majority of ll s This variant was called the Ultraphot lll The only difference between this and the later lllB is that in the latter exposure control in the large format photohead is based on a light reading from the centre of the picture area rather than just beyond its left hand side as in earlier models Both lls and llls were marketed in Met and Pol versions but these designations merely indicated the accessories provided with them the stands being standard issue Extract from Spike Walkers website
