It features the ‘aa’ Ahrens prism polarizer condenser and an Ahrens prism analyzer. The polarizer rotates through degrees, graduated in 5 degree increments. It has a brake for its rotation, and at its bottom end there is an iris diaphragm, the distance of which from the prism can be varied by sliding it up or down. The polarizer assembly can slide in and out of the optical path on a dovetail. It can be locked in the path with another brake. Above the polarizer are the optical components of the condenser with a top which can be flipped up or down for higher powers. The upper iris and flip-up condenser is on a second dovetail slider with its own brake and can also be slid out of the optical axis, independently.

Much of it was stored in the s when the Laboratory of Microbiology moved from its original building, and has rarely been disturbed since then. Some of the microscopes date from the late 19 th century, and even some of the 20 th century ones are more interesting than might be expected. The youngest of the companies represented in our microscope collection is probably the least well-known, especially outside the Netherlands. Founded by Dr Caroline E. Lili Bleeker and Gerard Willemse in , Nedoptifa rapidly became known for the high standard of their optical products.
They began with the production of binoculars for the Dutch army, but production was interrupted by WW2. The company cooperated with the Nobel prize-winner, Frits Zernike, in the development of phase contrast microscopy and held his patent on phase contrast microscopes.

April 26 th is the th anniversary of the birth of Ernst Leitz I — , who turned a small optical workshop in Wetzlar into an optics company of world renown. At the beginning of the 20 th century, the Ernst Leitz Optical Works rapidly became one of the leading suppliers of microscopes and optical products. The alert eyes of the man in the portrait define the image of a confident and resolute entrepreneur. The achievements that earned Ernst Leitz I the status he had acquired shortly before his seventieth birthday are just as immeasurable now as they ever were.
With the savings of his parents and his own competence, Leitz was able to save the small business from certain demise. At this time Leitz was 27 years old. The young entrepreneur seems to have been endowed with technical and commercial skills from the start. However, the innovation power that drove him and ultimately turned the workshop into an enterprise with an international reputation is unsurpassed.
When we meet up for an interview, the preparations are already in full swing. The 19 th century was the century of science. The further science advanced into the research of microorganisms, the higher the demands on microscopy. The most striking innovations were the cast lead horseshoe base and a joint between the base and the body tube and specimen stage. There was also an objective nosepiece to allow swift magnification change. Apart from these technical and ergonomic innovations, the greatest challenge of the microscope optics was to increase visibility in the micro range with powerful illumination systems.
