How do tem microscopes work
WebAnswer (1 of 3): If you've ever used an ordinary microscope, you'll know the basic idea is simple. There's a light at the bottom that shines upward through a thin slice of the specimen. You look through an eyepiece and a powerful lens to see a considerably magnified image of the specimen (typical... WebAn atom electron microscope is an advanced electron microscope that achieves exceedingly high resolution using electron beams, as opposed to light, to illuminate the specimen (atoms). This work is referred to as atom microscopy. This task is no easy feat, as atoms are an element’s tiniest unit.
