Basic Components of a Spectrophotometer - (Oct/19/2006 )

Hi everyone =)

I need some descriptions for the basic components (diffraction grating, aperture, photoelectric tube) of a spectrophotometer. It'd be great if you help me, thanks =)

search with google or wikipedia

That's what I already did. First I search it on my own, then I ask for help here if I still can't get what I want. =)
