Abstract
Light emitting diodes (LEDs) of different colours operated at low curr ents have been used as sources of feeble light for setting up of a pho ton counter. The intensities of light emitted from these LEDs have bee n measured with a photomultiplier tube (PMT) as a function of current through them. The light emitted from the red and green LEDs over a cur rent range 50 muA to 6 mA are found to be linear. Therefore, these LED s are best suited for setting up of a photon counter.
