Test platform III for the DAV5 V3 Raman spectrometer prototype 1 [a]

The plot below illustrates the IR beam divergence at 8 degrees and at 100mW/70mW pwr up.

The importance of these series of tests are, I am determining the material range of the semi-conducting metal oxide, in order to validate the spectrometer's ability to "see" in the infra-red range. This initial test is very promising because I didn't have to adjust the ROI very much to get a good reading.

So far the sensitivity of this particular cmos detector is very good and it helps that it was spec'd out for night vision use, both peaks are close to the specs of this IR illuminator at 805nm, although I cannot find enough detailed specs on it to determine any plus or minus variance. This project demands this kind of precision, there is NO work around!
