Microscope Leica TCS SP2

The confocal microscope is designed to acquire images with high spatial resolution cells or biological tissue by fluorescence. The principle uses a confocal pinhole (pinhole) adjusted to eliminate the fluorescence not coming from the focal plane. Lasers provide an intense light spot whitch is scanned on the preparation. The fluorescence emitted by each point is quantified and used to represent the brightness of the object (image).
This method provides a high resolution XY and XZ (gain up to 15% by XY and XZ 30% compared with an epifluorescence microscope)

Microscope Spinning disk LEICA/ROPER

This microscope provides an image with a xz resolution close to that obtained by a conventional confocal microscope. Scanning the sample is carried out by rapid rotation of a wheel consists of thousands of pinhole. When the wheel turns, the sample will be illuminated once per turn.
In the same way a conventional confocal microscope, only the fluorescence emitted from the focal plane will be collected by a CCD camera or sCMOS. The high speed of rotation of the wheel and an excitement to a relatively low level enables very fast acquisition while limiting photobleaching and phototoxicity.

Microscope plein champ

The microscope field allows the acquisition of images and movies by a CCD camera, live or fixed specimens. Such samples may be small (cells, bacteria, yeast ...) or tissue sections.

Acquisitions may be made in three spatial dimensions (X, Y and Z), over time, in white light or multicolour fluorescence mode. Our microscope is equipped with a black and white camera (phase contrast, DIC, fluorescent) and a color camera (histo slide).
