LEICA DMI 5000 microscope

The LEICA DMI 5000 microscope is an X, Y, Z automated inverted light microscope that allows you to work in brightfield, darkfield, interferential contrast in a simple way and polarized light.

Two software packages are available to process the images :

  • Multifocus that allows reconstruction in Z
  • Multistep that allows to do mapping.

Their use is illustrated by the snapshots below. The material used is a gray iron slats from water pipes in the city of Paris (Nital attack 4%)

The MultiFocus photo is obtained by overpotting 22 pictures taken in successive positions along the z axis. It makes it possible to obtain a clear image on the whole field of observation, the defects of focus due to the relief of the surface to be analyzed thus being corrected.
