Rare 1930's Carl Zeiss Laboratory Cabinet with Microscope. This magnificent scientific apparatus consists of a splendid microscope from the house of Zeiss of Germany, manufactured circa 1930's, with its original wooden case for extra protection. Microscope serial number: 251819. It has internal illumination (untested) that facilitated the interior view. The microscope is perfectly housed in a rectangular cabinet with slots and different accessories with all the necessary functions, which allow the manipulation of the apparatus from the cabinet itself. The appearance of the microscope is good, in spite of the years that have passed, with its original lacquer in good condition. The surface of the cabinet has some scratches typical of the passing of the years, which does not detract from the originality and magnificence of the piece. The microscope needs a little cleaning and is missing one of the four magnifying lenses it can hold. This type of apparatus was originally used to view dangerous objects under the microscope, which could not be observed directly. Carl Zeiss was a well-known optician in his native Germany who founded an extraordinary microscope company bearing his surname. He was undoubtedly a great visionary who developed from the middle of the 19th century novel physical and chemical instruments such as magnifying glasses, spectacles, telescopes, thermometers, barometers and scales. In 1847 he started with the production of microscopes, with which he soon became really famous. The small company of the beginnings was gradually gaining worldwide fame, as well as a greater share of the production base. A high production of microscopes was achieved by developing new and ever more perfect devices. In 1877 the microscope theory was published and Carl Zeiss improved immersion microscopy by replacing water with cedar oil. At the beginning of 1930 the technical limit had already been reached as far as optical microscopes were concerned, not achieving magnifications higher than 500-1000%, but undoubtedly achieving a true revolution in microscopic vision. A magnificent piece and a true innovation in its time, allowing us to see the past with different eyes. Cabin size: 41 x 31 x 30 cms.
