IR block filter: Need to get a spectral Analysis from 400-1200 nm

If anyone is attending college or has access to a spectrometer, I have a
small IR blocking filter that I removed from the Nikon N90s camera I
would like tested. It would be interesting to get a curve of this filter's
spectral response. It is 1/4 the size of a penny. Someone tried testing it
for me but it did not work out very well. Actually it worked fine but the
graph was from 1600 nm upwards, which isn't exactly useful for IR
photography.
Sincerely, Rolland
