[Translate to chinese:] 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.
[Translate to chinese:] 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.
