Immigrating to the United States from Germany in middle of the 19th century, Jacob Bausch and Henry Lomb began their association by manufacturing eyeglasses. He further refined the instrument with the incorporation of a rack and pinion coarse focus and fine focus enabled by a graduated wheel.Ĭonsidered the finest optical instruments of the time, different magnifications were obtained by inserting eyepieces of varying lens strength into the monocular head in combination with different objectives. His later microscopes used a draw-tube coarse focus and a knob controlled fine focus. Made of brass, many of these instruments had a black japanned base. Initially building single lens instruments, in 1857 his firm began designing compound microscopes. The German lens maker, Carl Zeiss, excelled at crafting precision lenses and began manufacturing microscopes in 1847.

Instruments manufactured in the 1800’s are the oldest an antique microscope collector can hope to acquire.įor further history reading feel free to follow our link on the History of the Microscope. Usually made of brass, the first microscopes were monocular instruments with simple lenses. They can only be found in museums and are not available to the average antique microscope collector. These first fledgling microscopes were generally built and used by a scientist. Later that century, Anton van Leeuwenhoek refined the microscope for biological research. Tilt 0 Degree -180 Degree, F = 170mm, with Eyepieces 10x or 12.His invention, a compound microscope, had a convex and a concave lens.
While the 150 is older than the 140 and 160, it has a distinct advantage of having more optical adjustment options than both the 140 and the 160.
The optical performance of the Visu 150 is comparable with the newer models Viso 140 and Viso 160. However, the S7 is more compact and manually balanced which can further reduce the footprint of the Viso 150. The Visu 150 is compatible with the S7 floor stand and the S5 floor stand. These features enable the microscope system to emit a red reflex for Cataract surgery. It is also equipped with a zero to one-hundred eighty-degree inclinable binoculars, a versatile objective lens, and can provide a predetermined number of illumination angled. The footswitch is designed to control at least 10 functions which can enhance the operational utilization of the whole system. Developed by Carl Zeiss Meditec, the Visu 150 is a reliable, compact, and versatile operating microscope that is specifically designed to handle routine and complex procedures in the field of Ophthalmology, such as Cataract, Cornea, Glaucoma, and Retina procedures. The illumination system of the Visu 150 is controlled using a waterproof footswitch. The Zeiss OPMI Visu 150 is a precision surgical microscope specifically designed for use in ophthalmic applications.
