Although this is slightly thread off topic, it is topical if -H mode switch is being used for the i1pro
The task here is to resolve if indeed the -H switch can return results of higher resolution, then if that is true, does it come with caveats like increased noise or some other loss greater than the gains.
True testing methods with this sort of thing is a problem outside lab setups where you have absolute control over all aspects.
First problem, the need of higher resolution spectro than the i1pro 10nm and 3.33nm -H mode.
Idealy a CS2000 would be the choice device, however I have a Jeti1211 which is highly regarded and research capable.
Light source, this is a problem. You might think that just measuring a display might be enough, maybe it is, but there is issues with this where I can show you an example of in the following image.
The problem with source light spectra is chance of spectra match ups. That is the peak by chance falls on the default 10nm point and therfore the difference between 3 and 10 is nothing.
So we need to control the sprectra, it just so happens I have a special filter for lab work sitting on my desk.
The following is this filter and it's transmission spectra, measured via a Cary 50 lab UV-vis spectra 0.5nm 190~1100nm (just happen to have one on my work desk)
Note: this graph is the Cary50 spectro, I have not compared the i1pro in this chart.
What I have compared is 10nm, 3nm and 0.5nm transmission spectra through this filter. The idea is to look for expected differences between the different spans.
It is note worthy that it shows something I expected, chances of differences and no difference in spectra peaks.
What is useful is the peaks in this filter show differences in regions of visible light and so viewable by the i1pro.
So atleast I have a useful light filter to generate repeatable peaks of light spectra outside the source.
Unfortunately the Cary50 light source is an internal lamp, so I can't use the same light for the Jeti or i1pro. However because I can now control spectra peaks with the filter I might be able to use something as simple as daylight, which is arguably more consistant than a display.
onwards and upwards.
