A Stanhope lens is a type of optical lens that is used to magnify and display images. It is typically made of glass and has a specific design that includes a convex lens with a concave mirror. The key feature of a Stanhope lens is its ability to project an image of a scene onto a surface, such as paper or a screen. Stanhope lenses were historically used in early photography and for viewing slides, as they could produce magnified images of small photographs.
