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.
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.
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.
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.
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-200 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-200 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 CR-200 has been designed with a direct viewing system that is easily detachable from the instrument's main body (e.g., snaps in and out manually), and can be replaced with a different type of viewing system depending on the user needs allowing the viewer more comfortable use better suited for the experiment/test setup than a traditional, fixed viewing system.
The direct viewing system has been utilized for several decades in optical measuring instruments. Typically, the eyepiece is in a fixed location on the instrument and is otherwise non-movable. As such the viewer must align himself or herself with the angle of the viewing optics to use the eyepiece. This can be disadvantageous in situations where the eyepiece is in an inaccessible and/or uncomfortable spot for the viewer. The CR-200 overcomes the limitations of the typical direct viewing system by offering the horizontally rotatable viewing system VO-201 and the horizontally and vertically rotatable viewing system VO-203.
For those cases where the CR-200 is mounted vertically on a fix test fixture or a robotics controlled XYZ table, the Perpendicular Viewing System VO-202 is an alternative to the rotatable viewing system VO-203 that can also be used with an instrument that is mounted vertically.
The VO-204 is a very compact viewing system that couples to a small C-Mount camera for positioning and monitoring the measuring spot from a robotics controlled system.
