Abstract
The invention relates to a high aperture immersion objective particularly for uses in confocal microscopes where oil is the immersion fluid, which objective is composed of three lenses and/or subsystems comprising lens groups. An apochromatic correction in a range from 365 to 900 nm is achieved at high resolving numeric apertures of 1.3 to 1.4 and an object field from 0.4 to 0.625 mm by the specification of the optical components. Additionally, the immersion objective has sufficiently good transparency up to a wavelength of 340 nm.
