While confocal microscopy uses a pinhole to reject out-of-focus light to generate the optical section, a multi-photon (or 2-photon) microscope uses a pulsed infrared laser to stimulate fluorescence ...

The Cell Imaging Center houses two types of confocal microscopes: the Olympus FV1000 and the Zeiss LSM700. In confocal microscopy, laser light is focused into a very small spot and is scanned across ...

On most of the occasions that I write about microscopy, I talk about big table-top devices with fancy lasers attached to one end and fancy geeks attached to the other. Yet, in my excitement over these ...

Device could open up new areas of research on materials and biological samples at tiny scales. CAMBRIDGE, Mass. — Researchers at MIT, working with partners at NASA, have developed a new concept for a ...
