A Stanhope lens is a simple, one-piece microscope invented by Charles, the third Earl of Stanhope. It is a cylinder of glass with each end curved outwards, one being more convex than the other. The focal length of the apparatus is at or within the device so that objects to be studied are placed close to or in contact with the less curved end. Because its construction is simple and economical, it was popular in the 19th century. It was useful in medical practice for examining transparent material
