Through a lens darkly

By oojeyboojey

Hard light

An assortment of lenses and shapes cut from glass and clear perspex, lying on a bed of dusty cotton wool inside a box that might be as old as I am. They were originally made to demonstrate the simple magic of making rainbows and explain ray optics to students. Now, they lie unused and unloved on a desk in a laboratory.

These are the kinds of unusual treasures you can find lying around in a Physics department.
