band radiance?

Hey, /sci/, help me out. I have a beam of light at color temp 2900 passing through an interference filter with central wavelength 589 nm (+ or - 2 nm). How do I go about finding the amount of light which makes it through the filter? The only blackbody radiation calculators I have are either horribly inaccurate or unable to accept a range of wavelengths less than 100 nm.

several free internets and much love to anyone who can point me in the right direction.

What the FUCK are we going to do with even ONE free Internet?

If you're going to let a single troll (and a half-assed one at that) get to you, you shouldn't be here. lrn2patience.
