Thanks again for all the info regarding Jeti spectros!

Now I'm looking at high-end colorimeters to accompany the spectro and trying to decide between K10-A and K-80. Now, everyone I know around here is using K10-A and I don't know any who's using K-80. Specswise they seem to be pretty damn close to each other, but are there less-known reasons why I should definitely pay the extra 1500€ for K10-A? Calibrated devices would be large gamut LEDs, Laser Projectors and (likely in the future) OLEDs.

Hi Jonahan,

I was fortunate to pickup up a used Admessy colorimeter. They're incredibly fast and accurate. Before you limit yourself between those two model, you can also check them out too. They are also fully supported by ColourSpace at the right license level.

Cheers,

Jonathon

Thank you, I'll check them out as well!

Th K80 is not suitable for large displays with less dense pixels.
It's lens is too small.
It is aimed at small high density screens such as mobile phones.

What about CR-100? Seems like a very good alternative, though K10-A seems to have somewhat better low-light reading capabilities, but since I don't have practical experience with high-end colorimeters, I have to ask how noticeable is the difference in performance between K10's 0.00006 and CR's 0.0007, especially when calibrating OLEDs?

That is a choice only you can make.
Other than pointing out probe limitations, we do not make recommendations.

I can understand that, so let me re-phrase the question: Is CR-100 capable of giving good results on OLEDs?

What matter most when looking at meter specs are the Chromaticity Accuracy and Chromaticity Repeatability. The CR-100 is better than the K10-A in those two aspects as it is accurate and repeatable down to 0.069 nits with a 20 sec exposure. The K10-A .... roughly 0.25 nits and higher. Not that different, but those are the numbers,

If you are only calibrating flat panel displays, get the CR-100.

Is it not suitable for projector calibration?

Any probe can be used for projector calibration.
(I can't think of any that can't...)
But some probes are not suitable for emissive displays.
And that is mainly due to not being able to be used in 'contact' mode.

The CR-100 can be used with projectors. However, it lacks setup alignment precision because it does not have an aiming laser nor viewfinder to see the exact spot you are measuring. That is why my last post stated if you are only doing flat panel display calibrations, the CR-100 is a better buy compared to the K10-A.

We have always use the 'Measure Area' method for probes on projectors, as the alignment systems used (other than the optical viewfinders as CR probes can have (but at not recommended for the Colourimeter as it reduced the probe's sensitivity - see CR-200) are not accurate.

The Measure Area method just means putting up a square white patch of the correct size for the probe's measurement area at the given distance, and with continuous reads active align the probe for the highest nits value.
Simple, and works very well.
