Wide-field microscope (Olympus/Microvision)

This microscope in fully motorized straight configuration (Provis Olympus) is dedicated to the mapping of colored histological sections or any sample marked by fluorophores. Single field acquisition in image stacks and/or multicolors is also possible. The system is equipped with a motorized stage and 7 lenses (from 4x to 100x) as well as two cameras (Sony XCD-U100CR color camera, and Hamamatsu ORCA-ER B&W camera). The image acquisition and processing software Histolab and Archimed, (Microvision) allow carrying out in real time, at acquisition, various measurements on tissues or cells: median, surface, coloration density, counting and the corresponding statistical analyses.

AZ100 Fluorescence Macroscope (Nikon)

Very flexible, this macroscope allows fluorescence and trans-illumination analyses on small rodents, embryos, marine models, plants, eggs, tissue explants, histological sections and cells in culture. It covers fields of view from 0.042 to 1.4 cm in diameter thanks to its three lenses and eight zoom/lens levels. The large field images obtained also allows imaging in light background or fluorescence. This macroscope is equipped with a halogen source for fluorescence and optical filters for the analysis of fluorescence from 521 to 615nm in emission (excitation from 495 to 596 nm). Kinetic and multiplane analyses are also possible on this instrument, via the NIS Element software.

Image processing stations and software

ImageJ & FIJI

Open source software. Their openness, their active community and the richness of their plugins allows the most advanced image processing in many areas. The software architecture integrates many plugins and offers scripting possibilities.

Some applications and their plugins: Co-location: quantification of the colocation of structures on different fluorescent channels (plugins: JACoP, Colocation); Color segmentation: color-based segmentation (plugins: Threshold Colour, Color Segmentation, Color Inspector 3D); Neuron tracing: reconstitution of neuronal morphology (plugins: NeuronJ, NeuriteTracer); Group several stacks together: useful mainly in imaging living cells (plugin: concatenate)
