Optical Equivalent of Debye-Scherrer Interference U19172

Instruction sheet

02/08 ALF
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 structure 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.
