Nonconfocal 3D Microscopy Combines Real-Time Images with Depth of Focus
The technique holds the promise of greater accuracy and efficiency for neuroscience, vascular research, and cytopathology. Stereo 3D microscopes produce real-time 3D images, but they are usually limited to low-magnification applications, such as dissection. Most compound light microscopes produce flat, 2D images because high-magnification microscope lenses have inherently shallow depth of field, rendering most of the image out of focus.
