Light tables are humble but extraordinarily useful devices. Tools that laboratories, art studios, and similar places would be extremely unwise to go without. Though there are, of course, variations between one kind of table and another. Some may come equipped with special features that make them better suited for some tasks rather than others. However, the basic concept that underlies them all is simplicity itself. At the bottom, they are often just tables that emit evenly distributed light across their surfaces from a light source found below.
