CR-250-RH SPECTRORADIOMETER

Spectrophotometer/Colorimeter

The CR-250-RH is a high resolution
spectroradiometer/spectrophotometer in a very
compact footprint with a 5 nm bandwidth and 1.6 nm/
pixel resolution that excels in low-light, highly accurate
wavelength and color measurements. It’s ideal formeasuring current and future display technologies.

DESIGNED FOR PERFORMANCEThe ruggedly constructed housing of the CR-250-RH is made of machined aluminium and stainlesssteel, 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 1.0 pound (0.45 kg), and it is the perfect tool for display inspection and calibration andfor mounting on fast moving XYZ tables. Its small size and shape allows for several CR-250-RHs tobe mounted in the same motion control system and the simultaneous measurement of several spots
in the same display.

VERSATILE INTERFACE OPTIONSThe CR-250-RH 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-250-RH can also be controlled by an
Ethernet 10BASET/100BASE-TX IEEE-802.3 compliant connection.

OPTIONAL EXTERNAL TRIGGER PORTThe CR-250-RH can be equipped with an optional External Trigger Port which enables remotemeasurement 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.

APPLICATIONSThe CR-250-RH was designed specifically for the professional calibrator. It provides a large spot sizeon contact measurements and a small divergence angle that keeps the measurement spot size within
desired dimensions for display panels and projectors calibrations.
The rubber hood allows to safely position the meter against the screen providing an excellent shield
for ambient light.

APPLICATION SOFTWAREThe CRIApp application is a streamlined, cross-platform, user-centric application designed to perform allcolorimetric - based analysis. It provides a familiar and consistent workspace no matter which platform you
are in. The CR-250-RH 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 AutomatedTest Environment.
In addition, a fully documented communication language with numerous real-world, sample templates areincluded as starting points for customers to build their own software tools using any of the current development
environments.

FEATURE HIGHLIGHTS██ Cross Platform: Your working environment is the same in every platform while taking
advantage of features specific to the host operating system.
██ Intuitive: The user interface is designed with a user-friendly approach with controls at
your fingertips, not hidden away in menus or complex preferences.
██ Connectivity: The software is engineered to support simultaneous data capture frommultiple 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 gridor charts. The software supports multiple types of measurements, and co-exists
gracefully within the same streamlined interface.
██ Spectral Auto Interpolation: The spectral data view supports automaticinterpolation of spectral data so that it provides seamless comparison between unlikespectra.
██ CRI & Gamma: Color Rendering Index visualization and gamma measurement modeis available.
The Colorimeter Utility is an accompanying tool that aids in updating, preserving and recovering the state of the instrument.
