This microscope was made in USA, in Rochester NY. It belonged to my father, who studied marine biology. It has a backlight that works, 3 objective lenses (3.5x, 10x, 43x) and 2 eyepieces (10x, 20x). This means the magnification ranges from 35x to 860x. Course focus and fine focus both work. It is very solid. Built to last.
