Judging by the photograph displayed on basiCColor web site, the DISCUS looks a lot like Sencore ColorPro V. Looking at the specs of the DISCUS colorimeter, I get the following : Messbereich (effective range): Luminanz: 0,05 bis 2.500 cd/qm (from 0,05 to 2500 cd/m2 -- OK) Chromaticity: 0,05 bis 2.500 cd/qm (0,05 to 2500 cd/m2 -- I am not sure what to make of this spec?) Genauigkeiten (accuracy): Luminanz: +/-2% 1 digit ( 1 ~500cd/m2 ) --- Same as Minolta CA-210, spec'd at ±2%, ±1 digit of reading Chromaticity: +/-0.002 Illuminant D65 -- Same as CA-210, spec'd at : ±0.002 for white @160 cd/m2 Chromaticity: +/-0.0025 CCT 4000-15000K -- in order words, DISCUS is optimized for D65 Chromaticity: +/-0.0065 für andere Farben (for other colors) -- Sencore CP6000 ColorPro V is spec'd at ± 0.006 Kalibrierung: PTB traceable On comment on all these instruments's traceability. I made a trip last spring at NIST, during a CORM meeting, and they said that a lot of instrument manufacturers incorrectly label their instrument "NIST or PTB-traceable" when in actuality, it is the *lamp* that they use to make the measurements that are NIST or PTB-traceable. Or have I got that wrong? This being said, I might be interested in using a DISCUS myself, provided a lot of conditions are right. I mean, there would be little point using such an expensive instrument with software that does not take full advantage of its advanced capabilities, right? So this means that, until Karl Koch donate a DISCUS to Graeme, for support in Argyll, it's not going to happen. And even then, who would Graeme be adding DISCUS support for? At US$1100 a crack, I don't know too many users who are crazy enough to buy this instrument out of curiosity -- maybe yours truly ... ;-) Now, one last bit of information, if I might. As I said before, anyone really interested in this instrument is going to expect to take full advantage of it. This means, yes, using the basiCColor Display software, since it's bundled with the instrument and since it's designed to take full advantage of its capabilities. But, that's not all, IMO, because, more critically, the monitor where the DISCUS will be used better be fully supported by the software! Suppose I buy the system and plan to use it on my "high-end" monitor, which features internal hardware LUT. Suppose further that basICColor Display does not support my monitor at the hardware level (I've seen this). Then what : I've paid all this money for sub-optimal results? Better carefully look at the specs of the package *before* ordering. Incidently, Graeme, not only do you need a sample of all the instruments you want to support in Argyll, in order to test and debug, but if we'd want to go further, you would also need a sample of monitors you want to support with those instruments, in order to test and debug too -- would you care for a NEC PA241W? Otherwise, Argyll is never going to be able to calibrate any system at the "hardware", monitor internal LUT level, right? Best / Roger BTW, I've been kicked-out of the ColorSync List -- for no apparent reason. I realize I would have like to put this post on the ColorSync List too, but it seems this List has more interested readers these days ;-) > > What do you think about new high-end basICColor DISCUS colorimeter > > that is not very expensive? > > I haven't come across it, as it seems to have only been announce recently.
