Designed for PERFORMANCE
The ruggedly constructed housing of the CR-300 is made of machined aluminium and stainless steel, and 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 pound (1.134 kg), and it is the perfect tool for display inspection and calibration and for mounting on fast moving XYZ tables. Its small size and shape allows for 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 net book. As an option, the CR-300 can also be controlled by an Ethernet 10BASET/100BASE-TX IEEE-802.3 compliant connection or a RS-232 port.

The CR-300 can be equipped with an optional External Trigger Port which enables remote measurement activation from either a push button, a peripheral device, or by hardware trigger signals to measure strobes/pulsed lights, and start/stop signals. This option is ideal for fast temporal events that need to be precisely synchronized for measurement or data capture.

Screw-on rubber hood adapter is included for contact measurements. Measurement spot diameter on contact measurements is 8 mm for a unit that has a 2 degree aperture and 14 mm for a unit that has a 1 degree aperture.

Future proof your CR-300 with additional custom color matching functions.

The CR-300 allows uploading up to three sets of custom CMF’s.This “custom” CMF’s can be alternate standards proposed by different organizations, such us Judd-Voss 1978 or custom CMF’s a researcher may be working on.

And lastly, Powerfull application.
The CRIApp application is a streamlined, cross-platform, user-centric application designed to perform all colorimetric - based analysis. It provides a familiar and consistent workspace no matter which platform you are in. The CR-300 comes standard with a built-in, easy-to-learn command interpreter, for users to quickly create their own dedicated software to perform specific measurement tasks or for inclusion in an Automated Test Environment.

In addition, a fully documented communication language with numerous real-world, sample templates are included as starting points for customers to build their own software tools using any of the current development environments. LabVIEW driver is available upon request.

Cross Platform:
Your working environment is the same in every platform while taking advantage of features specific to the host operating system.

The user interface is designed with a user-friendly approach with controls at your fingertips, not hidden away in menus or complex preferences.

The software is engineered to support simultaneous data capture from multiple connected instruments based on the contextual task at hand. Select an instrument to take a reading or simultaneously use all open instruments.

Data Visualization:
Measurements are presented in a customizable tabular grid or charts. The software supports multiple types of measurements that can co-exist gracefully within the same streamlined interface.

Spectral Auto Interpolation:
The spectral data view supports automatic interpolation of spectral data so that it provides seamless comparison between unlike spectra.

CRI & Gamma:
Color Rendering Index visualization and gamma measurement mode is available.

The Colorimeter Utility is an accompanying tool that aids in updating, preserving and recovering the state of the instrument.
