ABSTRACT:
An objective lens system for microscopes comprising a front lens group consisting of a first positive cemented doublet component, a second positive single-element or cemented doublet component and a third positive single-element or cemented doublet component, and a rear lens group consisting only of a negative three-element cemented lens component, said objective lens system having a large N.A. value and being so adapted as to be usable for fluorescence microscopy by using a glass material showing, at a thickness of 10 mm, a transmittance of 80% or higher at wavelength .lambda.=365 nm which enhances transmittance of the entire lens system above 60%.
