    It's a sphere made of a dielectric material. A "dielectric" is a (usually) electrically insulating material such as you put between the plates of a capacitor in order to increase the capacitance.

    What is the context of your question?

    it is in relation to optical tweezers, i read on wikipedia that they can be used for things such as a dielectric sphere.
