In the past twenty years, digital microscopes have been revolutionizing the field of optical microscopy. By using optics that are optimized for image capturing, several technical advantages are created: superior depth-of-field, large working distances, reproducible lighting, all while maintaining exceptional brightness and clarity. Learn about the concept and history of the technology and how it applies to a wide range of applications - electronics, aerospace, semiconductor, medical device, etc. Imaging and lighting techniques to control glare and reflectivity, enhance surface texture and view low-contrast targets will be discussed. Coupling all of these technologies into a single device greatly reduces analysis time and improves documentation.
Hope some people are interested.
