Such information consists of the maker's name and address, dates on the microscopes or documents that accompany the microscopes, manufacturer's archives, lists of serial numbers vs. In dating the instruments presented on this website, use was made of whatever information happened to be available.
Use the drop-down menu link above to choose the country of origin. Before the introduction of electric fan cooling, water-filled cuvettes were used as heat filters for larger projectors.ĭue to the sensitive components installed in the slide projector, the "fragile" option is included in the shipping costs.The list of microscopes presented below is organized with respect to the country of origin and further with respect to the instrument maker. In particular, the optimization of the condenser system as well as the brightness of the light has been continuously worked on at the same time as reliable and adequate heat dissipation and thermal protection for the slide. This projector, as well as its successors until the 1960s, also allowed the use of an attachment for the projection of film strips instead of the framed slide. The first projector was the Uleja with a 3-lens condenser system and a focal length of 80mm when using a 100 watt lamp. Leitz started producing slide projectors in 1925, the year the Leica 35mm camera was introduced. History of projector production at Leitz / Leica The dimensions (with dia approach) were: L: 23cm, width 13cm, height: 24.5cm Weight: 3.2 kg. The lenses to be used were the then Leica lenses with 50, 73, 90 and 135mm. However, the difference is the Ubela (with film roll holder) and the Udano (with slide slide). The lamp housing had the order word "Udimo", which is why the entire range of projectors was also named Udimo 100, 300, 500 and 750, depending on the lamp size (although the latter had other housings). The projector VIIIa is the first to have a slide change slide, film roll holder, rotatable, lamp adjustment by three screws at the bottom, the lamp can be easily accessed by removing the lid of the lamp house. He was with the then offered Leica camera lenses (except the ELMAR 3.5cm) usable. In particular, the condenser system had been improved and the light output increased. This was the first system projector with interchangeable components and lenses. Dachbodenfund, from the days of my great-grandfather, works, with lots of accessories and spare lamp, see pictures.
