Abstract

Video microscopy has been an important application in science, medicine, and industry. It has also been used in many conservation laboratories as part of the daily routine of examining and treating objects. These microscopy systems are normally composed of a cooled charged coupled device (CCD) video camera and a high-resolution color monitor used together with a microscope. Further capabilities are gained by digitizing such systems with the addition of a video capture card and computer software. This enhancement makes it possible to approximate the side-by-side visual comparison capabilities of very expensive comparison microscopes used in the forensic sciences. Such capabilities can be a valuable tool in today's conservation laboratory. It is possible to use side-by-side visual comparison studies in the course of identifying materials, examining various interactions between materials during pretreatment spot-testing, or monitoring the actual treatment phase. This article provides a brief overview of digital video microscopy and examines some of its applications that may be suitable for routine conservation use.
