A light source is focused onto a pinhole to create a high intensity point source. The point source is located two focal lengths from a 6" spherical mirror (f = 1.5 m) to produce an image of the same size on a razor blade. The razor blade is positioned to block half of the light reflected by the mirror, while the other half of the light is picked up by the camera. The camera lens is focused on the objects held in front of the mirror.

A light source is focused onto a pinhole to create a high intensity point source. The point source is located two focal lengths from a 6" spherical mirror (f = 1.5 m) to produce an image of the same size on a razor blade. The razor blade is positioned to block half of the light reflected by the mirror, while the other half of the light is picked up by the camera. The camera lens is focused on the objects held in front of the mirror.
