Vertical resolution in the balance between numerical aperture and depth of field
Digital microscopy offers clear advantages for a wide variety of industrial quality inspections, particularly surface analyses. Fracture analyses, analyses of inclined or vertical surfaces or onsite inspections of large parts such as turbine rotors are just a few examples in which the strengths of digital microscopes make the biggest difference. But what are the key criteria for successful use of digital microscopes and which parameters affect the three-dimensional imaging to be expected for these specimens?

Enthralled by classical color
25 January 2011
Everyone has admired the brilliant white marble of classical statues. However, new scientific research now reveals that Greek and Roman statues were most definitely not white but were decorated with elaborate ornamentation and brilliant colors.
Minerals such as blue azurite or green malachite were finely ground and mixed into binding agents such as egg or casein. Painting the statues made them more striking in appearance and also provided important information on the meaning of the artwork for viewers. The Ny Carlsberg Glyptotek in Copenhagen is a leading member of the Copenhagen Polychromy Network (CPN), an interdisciplinary research team that has already delivered significant research results. The current project is dedicated to studying the sculptures in the Glyptotek and recording all traces of paint. The team is already using a Leica M651 surgical microscope. Conservator Maria Louise Sargent is now also using a Leica DVM3000 digital microscope.
