COLOUR MIXING DEMONSTRATION PROJECTION

adminbenscience — Tue, 13 Oct 2026 17:08:07 +0000

A low voltage projection colour mixing apparatus. The unit comprises three individually moveable light heads, red, blue and green, which use individual lenses to project three coloured spots of light. By adjusting the heads the spots may be overlapped to produce the classic colour mixing pattern or superimposed to give a white disc that may be used for colour shadow work and secondary colour mixing determination. All three colours may be individually adjusted from 0% to 100% giving an almost limitless number of possible colours. Comes supplied with low voltage power supply.

Specially designed box holds the tube firmly and prevents the student from touching the electrodes. A black panel behind the Spectrum tube eliminates distracting ambient light and protects the tube from breakage. Operates on 220V A/C at 50Hz and is suitable for 20/26 cm tubes.

COLOUR MIXING APPARATUS DEMO

adminbenscience — Tue, 13 Oct 2026 16:41:12 +0000

The Irwin Colour Mixing kit is designed to demonstrate primary and secondary colour mixing.
The kit comprises, essentially, a scaled up version of our small colour mixing apparatus. A robust, 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 12V 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.
