The VHX-600 series digital microscopes from Keyence Corp. of America offer a depth of field that the company says is at least 20 times greater than that of conventional microscopes. The 54-megapixel three-CCD-mode camera and a selection of high-resolution RZ lenses with up to 5000× magnification provide chromatic aberration correction and image quality. The unit can be handheld or mounted on a multiangle viewing stand, and it incorporates vibration correction in real time. A 3-D image composition mode enables the capture of sharp images on specimens with large height differences. Illumination is integrated in the lenses, and the system includes a 160-GB hard disk drive and a 24× CD-R/RW drive.
