CR-110-TA Brochure

Temporal Analyzer

Features at a glance

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.

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-100 uses proprietary hardware and software for fast sampling of display luminance to compute flicker levels (or modulation amplitude) and dominant flicker frequency components.

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).

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.

Match Calibration

The match calibration method, allows the colorimeter to be correctly matched to a reference instrument

TEMPORAL Analysis

The CR-110-TA provides fast data captures at user-selectable sampling rates ideal for flicker and temporal analysis of modulated light sources, such as in the Solid-State Lighting (SSL) devices/ luminaries and displays with LED backlight dimming based on pulse-width modulation. An adaptive electronic smart noise-filtering algorithm reduces high frequency noise.

Flicker characterization is compliant with the IDMS (Information Display Measurements Standard) published by the SID’s (Society for Information Display) ICDM (International Committee for Display Metrology) working group. This includes the FFT (Fast Fourier Transform) method of calculating dominant flicker frequency and weighted flicker level to match the approximate temporal flicker sensitivity of the human eye.

RESPONSE TIME Analysis

The fast temporal captures at user selectable sampling rate of the CR-110-TA are ideal for response time analysis of light sources and displays. A smart peak valley noise suppression and moving window average filter enables accurate detection of response times.

Response time analysis is also compliant with the IDMS

Versatile INTERFACE options

The CR-110-TA is powered directly from any USB port and consumes only 120mA at 5V (600 mW), making it a portable instrument without the need for batteries or external power. 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-110-TA can also 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-110-TA 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.

Designed for PERFORMANCE

Ruggedly constructed, the housing is machined aluminum 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-110-TA is completely solid-state with no mechanical shutter or moving parts to ensure high reliability and long MTBF. Weighing only 12 ounces (340 grams), it is the perfect tool for display inspection or 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.

And lastly, Powerful application.

The PC-based software application is a streamlined, cross-platform, user-centric assistant used to perform photometric and temporal analysis. It provides a familiar workspace regardless of the platform used. All CR-110-TAs come standard with a built-in, easy-to-learn, English language command interpreter to control all aspects of 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.

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