Abstract: An objective lens system for microscopes designed for a magnification level of 60X and NA of 1.4, excellent in contrast and resolution, and comprising a first cemented doublet component comprising a plano-convex lens element and a meniscus lens element having a strongly concave surface on the object side, a second meniscus lens component, a third cemented component comprising a convex lens element, a concave lens element and a convex lens element, a fourth cemented component comprising a negative meniscus lens element, a biconvex lens element and a negative lens element, a fifth cemented doublet component having a strongly concave surface on the image side and a sixth cemented doublet component having a strongly concave surface on the object side.

Abstract: A microscope objective with magnification about 100.times. comprising six lens components wherein the third lens component is a cemented lens component consisting of three lens elements wherein the second lens element is a negative lens having strong power, the microscope objective being arranged that longitudinal chromatic aberration is corrected satisfactorily favorably and NA is larger than 0.9.
