American Optical Series 50 Binocular Microscope

    The light source is simple and dependable with only a reliable and simple on and off switch. These switches last decades. Some of the ones I have use an adjustment knob to raise and lower the condenser and they will be sold first. The other stands have a condenser with a limited range, as this was an attempt to teach good microscopy where you use the condenser iris to create contrast, not the knobs. There are also 2 stage dials, one has separate knobs on the top, the other has coaxial controls below the stage and cost slightly more. If you are interested, we will take photos of both and send them to you. This is a rugged and dependable microscope that will continue to last for many years to come.

At the present time we have 10 in stock.
