The HP Z model spectrometers have a white LED as their light source,
with no UV content, so they do not measure into UV and their spectral
export does not have data beyond 400-700 NM.
I have seen the Z's spectrometer described as being simular to:
1/ the Eye 1, which has a tungsten light source with some UV content,
cut out in the UV-cut version.
2/ the iSis, which has a UV Led and a white non-UV LED, using them
separately.
3/ the Colormunki in a recent message, one white non-UV LED.
Which spectrometer comes near the Z's model, light/sensor/grating? I do
not know, could be half the iSis, a whole ColorMunki but an Eye 1 is
unlikely given the light source. It also measures from a greater
distance on larger patches, I think the illumination must have been
increased.
