Abstract
An optical system for a scanning probe microscope provides both an optical on-axis view and an optical oblique view of the sample by means of two optical paths each providing an image to a CCD camera via an auto-zoom lens. A shutter alternately blocks the image of either view from reaching the auto-zoom lens. The CCD camera provides the optical image to a video display which also displays the scanning probe image, thus eliminating the need for eyepieces and allowing easy viewing of both the optical and scanning probe images simultaneously.
