Principles of operation
Fluorescent light from lasers filtered for emission produce an image from wide-field resolutions to super resolutions down to 60nm XY. A lattice pattern is placed in the light path to surpass the diffraction limit and produce super resolutions in lattice SIM. A grid pattern is placed in the light path to improve resolutions over wide-field.

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.
