An economical LED Ray Box, housed in traditional die cast enclosure. The unit is supplied with slit plate and battery pack as power source, which requires 2 x AA batteries (not included). The battery pack plugs into 4 mm sockets mounted on the Ray Box.Please note that when using a power supply, it must be DC and the volatge must not exceed 3 V. A higher voltage will blow the LED and invalidate the warranty. However, the LED assembly can be replaced. Takes 45 mm wide accessories.

Comprehensive light and optics set which includes a 3 beam ray box (each beam available in dual colours – white or red) and an array of lenses and prisms, teacher’s notes and 9 pupil work cards. The set is an ideal accompaniment to any advanced study of light and optics with experiments to show refraction and reflection through various shaped prisms and lenses, the splitting of light into the rainbow colours, how internal reflection is used in fibre optic cables and the appropriate lenses to use to correct long and short sightedness. Requires 3 x AAA batteries.
