Sir, I'm having problem on the spectrum whenever I place the cuvette with distilled water. It doesn't appear to look like with your curve, because it flattens from about 490+ nm.
Also Sir, why did you use 300ms in integration time for emission spectroscopy and 150ms for colored solution?
The spectrum of the distilled water is essential that of the light source. After saving the reference and the dark scans, make sure the light source is plugged in and working and the spectrum should appear. The integration time was reduced to optimize the spectrum on the intensity (and minus dark) scales. If the integration time is too high, the measurement will top out and not give an accurate spectrum.

Yes, you should be able to estimate the temperature of objects whose spectral peaks are the IR and visible (350 to 850 nm), assuming the objects are perfect blackbody emitters. For improved results, factor in the emissivity of the surface material from which the radiation is being emitted.

Can you use this spectrometer to analyze blackbody radiation to get the temperature?
