This beautiful vase-like structure is the skeleton of a single-celled organism called a radiolarian. Radiolarians live in large quantities as part of the ocean's plankton. When the radiolarian dies, it's shell sinks to the bottom. After millions of years of radiolarian shells "raining down" on the sea floor, they accumulate in great quantities. Much of the sea floor of the deep oceans are covered in this radiolarian "ooze".

Sample Chamber Left: the sample chamber located at the base of the column. Right: the lens and detectors located inside the sample chamber



Objective Lens ( left pic )

The lens that focuses the beam of electrons towards the sample is in the center of the picture. The parts off to the right of the sample are different detectors. One is for detecting the secondary electrons and the other is for detecting the backscattered electrons. The operator has the power to choose and switch detectors for use on each sample. Using the secondary electron detector produces a clear and focused topographical image of the sample. The backscatter electron detector produces an image that is useful when determining the make-up of the sample. Each element in the sample appears as a different shade, from almost white to black.

This is mounted on a specimen stub and placed on the stage.
