DetailsEnclosed in a robust case this broad sensitivity detector provides a simple solution to showing that the electro-magnetic spectrum extends either side of the visible. 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. The high sensitivity and linear response make the unit ideal for a whole range of investigations such as how much light is reflected from different papers etc.
Requires 9V battery (held inside the case) and multimeter with 200mV scale or similar (not included). Supplied with full instructions.
