High resolution confocal microscope

摘要

A confocal scanning microscope includes a light source which provides a light beam and scanning optics which sweep the light beam across the surface of a sample. Light from the surface or interior of the sample passes through a pinhole lens which focuses the light on a pinhole for detection by an optical detector. An image of the surface may be scanned using the optical detector. An optical element is inserted in a detection arm of the confocal microscope. The optical element provides angular magnification and natural divergence to the beam from the surface of the sample.
