Abstract :
The authors describe a grating spectrometer consisting of a slit, a transmission holographic grating, a lens, and a CCD (charge coupled device) camera. A frame grabber equipped in a computer digitizes the NTSC signal from the CCD camera. The system is relatively small (12.7 cm×17.8 cm×30.5 cm) and light-weight (5.4 kg). The system will measure the lumen output of modern fluorescent or compact fluorescent lamps more accurately than conventional filter-based photometers
