Fig 1: Commercial lens holder
A device which securely holds glass lenses for optical physics applications.
Available from suppliers or made from a simple wooden block, the holder enables you to firmly hold a glass lens stationary for use with ray boxes etc. Using multiple holders enables you to create an optical path allowing beams of light to diverge and condense with appropriate lenses in configuration.
The holders can also be used effectively with coloured glass or theatre-type coloured gels to colour a beam. They can also house diffraction gratings and slides.
