Understanding Spectral Bandpass of Monochromator

[tigger]

Hi.. can anyone please explain to me what does it mean by spectral bandpass of monochromator? i tried to look for it in my textbook, but i can't really find anything..
what i think is that this spectral bandpass gives you the size (wavelength range) of the wave component (after it passed the dispersive device) that can go through the monochromator... so when you do the analysis u get a band with this wavelength range.. is that correct?

Thanks in advance!

Hello,

I have found the following from http://www.pti-nj.com/tech_3.html :

"Spectral bandpass of the monochromators. The bandpass of commercial fluorometers may be varied between 0.5-30 nm. Doubling the bandpass of a monochromator will increase the throughput of light by a factor of four. Resolution, however, is worse at high bandpass. The bandpass may be adjusted by the analyst to balance sensitivity and resolution."

thank you so much!
