Physics
Dual Colour Laser
The Lascells semiconductor laser contains two independently controlled laser diodes, one at the standard 650nm red and a second at 532nm green. Both lasers may be simultaneously passed through a double slit slide and both diffraction patterns may be displayed one above the other for an immediate comparison.

Malus’s Law
Students can investigate the relationship between the proportion of transmitted light and the angle of rotation of two polarising filters. A graduated cartridge containing two polarising filters allows students to observe the change in intensity as they are rotated relative to one another.

Optics Bench Pair
This is an economical alternative to a mounted optical bench. Each of the acrylic components can be easily aligned against a metre rule (not supplied) so that distances between components can be easily calculated and investigations into magnification and focal length can be carried out.
