ABSTRACT:
A technique for positioning the tip of a stylus mounted on an arm attached to a cartridge for viewing through a microscope comprises a platform having a transparent plate attached thereto. The platform is adapted to support the cartridge so that the tip of the stylus contacts a surface of a transparent plate disposed between the tip and an objective of the microscope, the plate being prepositioned so that the surface lies in the focal plane of the microscope objective. The tip of the stylus is moved in a direction along the surface of the plate so that the stylus tip is centered within the field of view of the microscope objective. In order to guide the tip, the surface of the plate may have two raised ledges thereon, intersecting at a vertex centered within the field of view of the microscope objective.
