The detector area is only 1mm dia. so that it can be passed through the visible spectrum produced by a projector and prism. The output is monitored on a multimeter and gives measurable readings from 300nm to 1000nm demonstrating the presence of invisible UV and IR. Requires 9V battery and multimeter with 200mV scale or similar (not included).
