For more than 160 years Leica Microsystems has designed and produced top-class objectives for a wide variety of applications in research, industry and medicine. The innovation power of Leica Microsystems' optical designers and the experience and expertise of Leica Microsystems' precision optical engineers come together to provide microscopes with the best optics possible. A sophisticated, state-of-the-art production process yealds objectives that guarantee superlative image quality.    
   
In optics there are two basic categories of aberrations that require correction: monochromatic and chromatic. The main monochromatic aberrations are: spherical aberration, astigmatism, coma, field curvature and distortion. Chromatic aberrations can be divided into axial and lateral.    
   
Our top-performance objectives feature maximum correction and optical efficiency, and have already won several awards. All over the world, leading scientists trying to visualize, for instance, the finest cell structures with resolutions down to 20 nm rely on optics from Leica Microsystems.
