Confocal technology advantages
Widely used in bio-science research, confocal microscopy offers several advantages over conventional optical microscopy, including controllable depth of field, the elimination of image degrading out-of-focus information, and the ability to collect serial optical sections from material samples. The key to the confocal approach is the use of spatial filtering to eliminate flare in material sample images. The Nikon Confocal NEXIV uses a Nipkow disk, which features multiple, symmetrically placed spirals of pinhole apertures through which light is passed and split into mini-beams. As the disk rotates, each beam scans across a portion of the sample field and generates a 3D image. The image is projected into a digital CCD camera using optical sectioning technology. The result is a 3D image captured in one scan delivering highly accurate and reliable height measurement data.
