Rock the column

With the OneView camera, always have a “live” experience when you capture 16 MP still images and videos on your transmission electron microscope (TEM).

At 25 frames per second (fps) you can capture sharp images when you eliminate sample drift caused by environmental, mechanical and thermal sources. As frames are summed together, a proprietary drift correction algorithm aligns each frame to build a single image.

This video shows the simulation of sample drift by physically pushing back and forth on the TEM column during image acquisition.
