This microscope was manufactured in 1903. It is based on a new design by Max Berger of Zeiss, first introduced in 1898 (Zeitschrift fur Instrumentenkunde, vol. XVIII, 1898, pp. 129-133). This microscope bears the serial number 37910, dating it to 1903. The major innovations of this design were a new type of fine adjustment and a limb having an integral handle (now, often referred to as a "Jug-Handle" microscope). While this microscope is perfectly suited for conventional work, this particular model was made for the purposes of photomicrography and projection. Accordingly, the main tube and the knobs are made of aluminum, presumably to reduce the weight on the fine adjustment mechanism, thus allowing it to be more sensitive and responsive when the microscope is inclined in the horizontal position (later versions of this model dispensed with the use of aluminum).

The plan and concave mirrors are here still connected via a dovetail with the carriage of the lighting apparatus. Later tripods of this type are characterized by an inserted into the end of the rack mirror fork. A large cross table takes up the rehearsal. This microscope stand has been offered since 1898 as the largest and for all microscopic work suitable tripod. Due to the large tube diameter, the microscope is very well suited for micro-projection and photomicrography. Funnels added to the tripod allow easy mounting of a camera.

Carl Zeiss Photo-Micrographic Microscope - Carl Zeiss Jena produced a range of photo-micrographic microscopes designed for use in photography and microscopy, with the ability to capture high-quality images of microscopic specimens. One notable example is the Carl Zeiss Jena Photo-Micrographic Microscope or Ph Stand, which was a popular model in the early to mid-20th century. This microscope was designed for use in photomicrography, which involves taking photographs of microscopic specimens using a microscope and a camera. It was known for its high-quality optics, which allowed for clear and precise imaging of specimens. It also featured a range of adjustable controls and accessories to customize the microscope for different types of specimens and imaging needs.

Carl Zeiss, "Bierseidel" Stativ IIIE, 1909


While this collection is focusing on pre-20th century microscopes, it was decided to include in it this very fine example of a transitional 19th-20th century microscope by the then (and now) world-leading optical company of Carl Zeiss, Germany. 

The profile of this instrument features an integrated “jug handle” (German: "Bierseidel"), cut into a squared off limb, a design that became popular among some producers between ca. 1900 and 1920. The serial number, 43430, indicates the production year 1909. Typical of microscopes of the turn of the 19th century to about 1930 is the combination of original lacquered brass tube, a remnant of the 19th century, with the black-painted ("japanned") limb and horseshoe base, to be replaced by the all-black body during the later decades of the 20th century.

Having already all the optical advances of the second half of the 19th century, scientifically set by Ernst Abbe at the initiative of Carl Zeiss, together with the advanced form which developed from the "Continental stand" of the earlier decades, this is a fully capable research instrument. Even today, over 110 years later, this instrument can still produce crisp and perfect views at any magnification between 50x and 1000x.
