Gatan 3View SBFS on Zeiss Sigma SEM - Available Now!

This system is capable of performing the following techniques:

Principles of operation

Serial block face scanning electron microscopy generates EM resolution 3D images. The system has an ultramicrotome inside the chamber of the SEM, which allows for automatic cutting of a tissue block. The surface of the block is imaged by detection of back-scattered electrons and then a thin section (30-50nm) is cut from the block face. The sample block is then imaged again and a sequence of images can be compiled automatically.

For more information, or access to this technology, contact Jennifer Santini.

Laser excitation, Emission filters and 2 CMOS cameras generate an image at a specific wavelength. Sample is moved through the sheet of light for Z stack acquisition.
