Confocal ImagingConfocal Imaging The key feature of confocal microscopy is that the “in focus”

region of a specimen is the region detected. There is controlledrejection of stray light.

This gives the advantage of observing specimens whose “out-of-focus” illumination contributes to degradation of the detectedimage resolution.

The disadvantage is that the confocal microscope doesn'tproduce a complete optical image of the specimen. So theoptical sections must be reconstructed to generate a 3D view.

The goals of a shared instrument grant areto provide access to state-of-the-arttechnology that will facilitate interactionand enhance scientific productivity.

A confocal microscope typifies thattechnology, which because of cost is usuallybeyond the scope of a single laboratory toeither purchase or maintain.
