The invention relates to a microscope objective with preferably anti-symmetric lenses or lens groups with an optical magnification of −100 and a visual field factor of 20. According to the invention the microscope objective consists of 9 lenses with 3 cemented elements, starting from the object side (left), a lens which is almost a hemisphere L1 with positive refractive power, a meniscus lens L2 with positive refractive power, a two-part cemented element G1 with positive refractive power, another two-part cemented element G2 with positive refractive power, a two-part cemented element G3 with negative refractive power, and finally a meniscus lens L9 with negative refractive power. By using cemented elements and lens pairings of the same construction, production costs can be reduced compared with methods of the prior art while image contrast is improved.
