using camera exposure meter for measurements

Okay, I am trying to measure the light frequencies output by a specific light bulb. I am measuring to see if there is a peak near 410-420 nm, and that intensity drops off going below 400 nm.

I have a Finepix S2000HD camera (fujifilm). Can I use its exposure meter to verify a peak frequency near 410-420 nm, or can the camera measure this low/accurately?

Please help.

I don't know of any camera (or handheld light meter for that matter) that can act as a spectrophotometer, at least by itself.

If the camera's meter can respond well to the violet end of the visible spectrum (the area you've specified) and if you have suitable filters that are very narrow-banded and large enough to cover the opening of the camera's lens, then you might be able to use the camera's meter to show differences in light level at each filtered wavelength.
