✦ Synopsis

A simple, inexpensive, battery-powered, portable luminometer which is based on a silicon photodiode is described. The instrument is intended to measure the light produced by chemiluminescent and bioluminescent reactions. The device shows a good detection limit and, in a bioluminescent reaction for adenosine 5'4riphosphate (ATP), detected 0.5 pmol in 1 ml of aqueous solution. The instrument measures irradiance from to lo-" Wcm-' at the sensor, within the range 300 to 900 nm.
