Polarising Filter Stress Determination
Demonstrate stress patterns in solids with this new and valuable equipment. Two polarising filters, mounted on a graduated frame are placed on a plastic base. Clear acrylic pieces of different shapes are introduced between the filters; when pressure is applied to the solids the resulting stress patterns are observed. An important method of demonstrating polarisation and stress. Includes instructions.

Fresnel’s Biprism
The 40 x 30 mm bi prism with optically worked surfaces is mounted in a frame with hinged joint and has a micrometer screw for adjustment. For determination of the wavelength of light by measurement of interference fringes produced by interference between two beams of light originating as a single beam from a common source and split by the bi prism.

Laser Reflection and Refraction Tank
Laser Reflection and Refraction Tank demonstrates the principle of reflection and refraction. The clear circular acrylic tank has a circular scale graduated on the white base of the tank, making it easy to measure angles. Adjust the pivot-arm mounted laser to any angle along its full 360° range and measure the angle of reflection or refraction. Rotate the laser and observe first a reflected ray, then both a reflected and refracted ray, and finally just a refracted ray. Leveling screws on the tank’s base make leveling quick and easy. The laser is attached to the pivot-arm by a magnet and can be removed for use in other experiments. Instructions included.
