CR-200 Tristimulus Colorimeter / Photometer
COLORIMETRY RESEARCH- Features
- Compact & Rugged: Constructed using machined aluminium and stainless steel and weighs only 12 ounces (340 grams). It is completely solid-state with no mechanical shutter or moving parts.
- Detachable View Finders: The measurement spot size is 23.0 mm at the end of the rubber hood and 31.7 mm at 100 mm from the end of the hood.
- Fast Captures.
- Response Time Measurements: The temporal captures at user selectable sampling rate of the CR-100 are suitable for analyzing response time as specified by the Information Display Measurements Standard (IDMS).
- Match Calibration: The match calibration method, allows the colorimeter to be correctly matched to a reference instrument.
- Accurate Filters: Each CR-200 goes through a strict quality control process. Every tristimulus filter is measured using a double monochromator to verify that the f1’ error is within the maximum f1' errors guaranteed.
- Large Spot Size: The measurement spot size is 23.0 mm at the end of the rubber hood and 31.7 mm at 100 mm from the end of the hood.
- Display Flicker Measurements: The CR-200 uses proprietary hardware and software for fast sampling of display luminance to compute flicker levels (or modulation amplitude) and dominant flicker frequency components.
- Four-Color Matrix Method Support: The Four-Color Matrix Method, developed by the National Institute of Standards and Technology (NIST) improves the accuracy of tristimulus colorimeters for measurements of color displays. The meter can store up to 20 profiles, enabling specific display technology to be perfectly matched.
Designed for PERFORMANCE
Ruggedly constructed, the CR-200 housing is 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. The CR-200 is completely solid-state with no mechanical shutter or moving parts to ensure high reliability and long MTBF. It weighs only 1 pound (0.45 kg), and it is the perfect tool for display inspection or for mounting on fast moving XYZ tables. Its small size and shape allows for several instruments 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-200 is powered directly from any USB port and consumes only 120 mA at 5V (600 mW), making it a portable instrument without the need for batteries. It 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-200 can be controlled by an Ethernet 10BASE-T/100BASE-TX IEEE-802.3 compliant connection or a RS-232 port.
Optional EXTERNAL TRIGGER Port
The CR-200 can be equipped with an External Trigger Port. The External Trigger Port/Sync Input enables remote measurement activation from either a push button or a peripheral device, while the External Trigger Port/Sync Output allows synchronization signals to measure strobes/pulsed lights, and start/stop signals. This option is ideal for fast temporal events that need to be precisely synchronized with the measurement or data capture.
Powerful application
The PC-based software application, is a streamlined, cross-platform, user-centric assistant used to perform all your colorimetric- based analysis. It provides a familiar workspace no matter which platform you are in. The CR-200 come standard with a built-in, easy-to-learn, English language command interpreter to control all aspects of their operation via a computer, tablet or smart device, making it easy for users to create their own software dedicated 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 modern computer development environments. LabVIEW driver is available upon request.
