ChromaPure Professional and Colorimetry Research CR-300 Reference Spectroradiometer

There are two color analyzers that professionals and dedicated enthusiasts generally seek: a reference spectroradiometer for the last word in colorimetric accuracy and a professional quality colorimeter. Unfortunately, such devices are not cheap. The Photo Research and Minolta reference spectros start at about $15,000 and go up to $30,000 +.

There is a new entry to the reference spectroradiometer market, the Colorimtry 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.

Summary


The CR-250 is one of the most affordable reference spectroradiometers available. Just mount on a tripod facing towards the source, connect to ChromaPure Professional, and then use as you would any other color analyzer.
