Tristimulus Colorimeter / Photometer
Ruggedly constructed, the CR-100-SD 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-100-SD is completely solid-state with no mechanical shutter or moving parts to ensure high reliability and long MTBF. It weighs only 12 ounces (340 grams), 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.
The CR-100-SD 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-100-SD can be controlled by an Ethernet 10BASE-T/100BASE-TX IEEE-802.3 compliant connection or a RS-232 port.
The CR-100-SD 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.
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-100-SD 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.
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.
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.
The CR-100-SD uses proprietary hardware and software for fast sampling of display luminance to compute flicker levels (or modulation amplitude) and dominant flicker frequency components.
The temporal captures at user selectable sampling rate of the CR-100-SD are suitable for analyzing response time as specified by the Information Display Measurements Standard (IDMS) .
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 and has been verified to be appropriate for cathode rays tubes (CRTs), liquid crystal displays (LCDs), and organic light emitting diodes (OLED) displays.
The match calibration method, allows the colorimeter to be correctly matched to a reference instrument.
The f1' value, specified in percentage error, represents the degree to which the relative spectral responsivity deviates from the CIE V(λ) curve.
