The CR-250 is the most affordable reference spectroradiometer available. Just mount on a tripod, facing towards the source, connect to ChromaPure Professional, and then use as you would any other color analyzer.
There are two colour analyzers that professionals and dedicated enthusiasts generally seek: A professional quality colorimeter for every day work (the "field" meter) and a reference spectroradiometer to keep the colorimeter accurate (the "reference" meter).
Unfortunately, such devices are not cheap. The Photo Research and Minolta reference spectros start at about $15,000 USD and go up to near $30,000 USD. The Klein K-10a, previously the only professional quality colorimeter on the market, retails at $7,000 USD.
Now there is a new entry to the referemce spectroradiometer on the market, the Colorimetry Research CR-250.
In our testing of the CR-250 we have found that it performs as well or better than the JETI spectros, the only other sub-$10,000 spectros on the market. It does this at the low price point of $6990.
The CR-250 has all of the accuracy expected of a reference device and is fast enough with enough low-end sensitivity that it can be used as a stanalone color analyzer, though most will probably use it to correct a colorimeter. Its speed, low-light sensitivity, and repeatability are world-class.
