Optics and prisms

Position a prism to split white light into its component colours. Predict the seven colours that will be produced. Test whether the colours seen are affected by the prism material: glass, flint glass or diamond. Explore whether filters add or remove colours from the spectrum. This learning object is a combination of three ...

Leitz arc lamp for microscope, c1912

This is a Leitz arc lamp for use with a microscope when coloured filtration was necessary and for photomicrography when ordinary illuminators were too weak or unsuitable. It was powered by a 6-volt battery. The lamp was made by Ernst Leitz in around 1912 and was used by Commonwealth Serum Laboratories, Victoria. The lamp ...
