    Diffraction Glasses

    The relationship between light and colour has never been explained so clearly as with these fun glasses. The double-axis diffraction grating embedded in the lenses ensure that, when looking through these glasses, almost any single light source can be split into 3D spectrum of the component colours. Specifically designed to fit students up to to KS3 but will fit older students.

    Polaroid Stress Analyser

    The Polaroid stress analyser allows students to view stresses which exist in clear plastic materials. This simple apparatus consists of two crossed Polaroid filter squares (i.e. axes perpendicular to each other), 65 x 65 mm, on a plastic handle. A gap between the Polaroid squares allows clear plastic shapes (or even a clear ruler) to be placed between them, to view any stresses within the material the stresses show as coloured areas and lines within the plastic. The analyser comes with two cut-out shapes which can be compressed to alter the stress patterns. Additional shapes are also available separately (OP74725).

    Polarimeter

    A simple, cost-effective polarimeter suitable for student use. A monochromatic light shines through a polariser at the base of the polarimeter and through a sample tube containing the solution for testing. A second polariser located in the eyepiece is then rotated and the angle of rotation/extinction measured on the integral scale. Requires a standard DC power supply to power the light source.
