1 Colour filter, red
2 Pinhole aperture slide
3 Disc with cross lattice
4 Colour filter, green




1. Description

The Optical Equivalent allows an experiment
that models the Debye-Scherrer effect as seen
in the electron deflection tube using visible light.
The equipment set comprises an aluminium disc
mounted on a hollow shaft which rotates in a
ball-race inside a plastic holder. Located in the
bore of the shaft is a cross lattice. The rotating
disc serves as a model of a polycrystalline struc-
ture such as the carbon grating in the electron
deflection tube. The set also contains a pinhole
aperture in a slide frame, one red and green
plastic colour filter.
