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.
