The ruggedly constructed housing of the Colorimetry Research CR-300 Tristimulus Colorimeter/Photometer from SpectraCal is made of machined aluminum and stainless steel, and it can withstand high acceleration rates for the most demanding motion positioning systems and environments. All optical components are fixed to ensure that no optical misalignments occur due to vibration, shock, or high acceleration/ deceleration rates.
It weighs only 2.5 lb, and it is the perfect tool for display inspection and calibration and for mounting on fast-moving XYZ tables. Its small size and shape allow several CR-300s to be mounted in the same motion control system and the simultaneous measurement of several spots in the same display.

Versatile Interface Options
The CR-300 is a USB 2.0 compatible device, remotely controlled by the host software from any personal computer, laptop, or netbook. As an option, the CR-300 can also be controlled by an Ethernet 10BASET/100BASE-TX IEEE-802.3 compliant connection or an RS-232 port.
Custom Color-Matching Functions
The CR-300 allows uploading up to three sets of custom CMFs, which can be alternate standards proposed by different organizations, such as Judd-Voss 1978, or custom CMFs a researcher may be working on.
