Direct-vision prism according to Amici, consisting of three prisms (crown glass/flint glass/crown glass). Particularly suitable for experiments on optical bench, e.g. experiments on spectral lines and complementary colours. Blackened outer ...
Inverting Spectacles Complete with two fully rotating inverting prisms in a shielded spectacle frame. The inverting prisms produce a lateral inversion of the rays – the world thus turns "upside down". Besides being a lucid demonstration ...
Set of prisms for demonstrating the design of an achromatic prism and a direct vision prism. Consists of a thin flint glass prism, as well as thin and thick crown glass equilateral prisms.
The two thin prisms deflect a light beam equally strongly ...
