3D Visualisation

25 January 2011

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.

Leica VZ700 C - One Lens for macro to micro

19 January 2011

The new Leica VZ700 C zoom lens has a 7:1 zoom in combination with three fixed mount objectives on a turret to provide an effective zoom range of 70:1.

The lens is compatible with the Leica DVM3000 and Leica DVM5000.

The parfocal objective lenses provide a constant and ergonomic working distance (10 mm) across the entire magnification range from 35x up to 2500x, with a field of view ranging from 8 mm down to 0.12 mm (horizontal).

The magnification is automatically registered by ACS encoding technology for the zoom level and selected objective lens, thus having the correct calibration information with every image acquired.

  • Connects to Leica DVM3000 and Leica DVM5000
  • Magnification range from 35x to 2500x
  • Zoom lens with 3 Objectives
  • Dual illumination mode – bright field, dark field, and any mix of the two
  • Various illumination adapters for contrasting
  • Encoded zoom for automatic readout of magnification
  • Parfocal objectives – no need to adjust focus when changing magnification
  • Parcentric objectives – no shift in image position when changing objective magnification

Illumination selector

Another unique feature of the Leica VZ700 C is the dual illumination capability to provide both co-axial (bright field) and ring lighting (dark field) illumination. The user can choose either illumination mode by simply turning a dial, without the need for changeover or other accessories. The change between co-axial and ring light is continuous, so any setting in between can be chosen for a mixed light situation.
