"Crystal Ball" Photography
From the University of Western Australia
Photography by Paul Bourke
Winner in the AIP (Australian Institute of Physics) Photographic Competition 2012.
Title: Ball optics.
Description: This photograph is taken near the reflection pool on the
University of Western Australia grounds. It is a photograph of a clear
glass sphere and can be used to illustrate a number of optical
principles. These include, but not limited to, the optics of a
spherical lens, specular highlights, and depth of focus (camera lens)
as it relates to the lens aperture. The optics of a spherical or so
called "ball lens" includes the ability to collimate or focus light.
In practical terms they are often employed to improve coupling in
fiber and laser optics as well as being used in endoscopy and optical
pick-up devices such as bar code scanners.
