    Newton's Colour Disc

    This Newton's Disc consists of an aluminium plate with coloured segments printed on it. The colours represent the colours of the visible spectrum (red, orange, yellow, green, blue, indigo and violet). When the disc is rotated and the speed increased, the colours start to blur and fuse together and then mix so that the eye, unable to respond rapidly enough, sees this effect as white light. Mounted on base with handle at rear to turn the disc. Weight: 0.8 kg. Dimensions (L x W x H): 250 x 150 x 25 0mm.

    Colour Mixing Box

    This unit contains three coloured light sources (red, green and blue) projected onto screen in overlapping circles. The unit is self-contained, meaning no setup is required, and can be used comfortably by 2-3 pupils at time. The brightness of each light can be controlled independently, allowing any combination of the three. This allows the demonstration of composition of any colour using just the primary colours. Requires 3 x AA batteries.

    Newton's Colour Wheel, Premium

    This motorized Newton's colour wheel is useful for demonstrating that white light is composed of combination of different spectral colours. Comprises a disc with different coloured sectors mounted on low voltage (6V DC) motor box with integral 4 mm sockets. When the disc is rotated at fast enough speed the colours merge to form white (usually off-white). Requires standard variable laboratory power supply (1-6 DC).

    Colour Mixing Apparatus

    An upright case contains three, high powered, accurately colour matched LEDs, each of which has infinitely adjustable brightness. Also supplied is a large, free standing, primary colour shadow mask,a hand held secondary colour mask and a 12 V plug top power supply. The system allows the teacher to project large primary and secondary colour mixing disks onto any vertical surface and to adjust the colour saturation to mix virtually any colour (how do you produce brown). Unlike other systems the purity of the resulting white is outstanding. The unit is extremely easy to use, is easily transportable and comes with full instructions. The only other requirements are a white wall and a darkened/blacked out room. The system may be used to demonstrate both secondary and primary colour mixing, colour shadows and colour reflection/absorption.

    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.
