How Does It Work?
A compound microscope is a type of optical microscope that tends to have magnifications in the mid to high range for optical microscopy (ours has magnifications between 50X and 500X although there are technologies that enable magnifications as high as 800-1000X in certain conditions). A compound microscope has a single set of objective lenses and the image is then duplicated, resulting in identical images being sent to each eye.
