Designed for PERFORMANCE

Ruggedly constructed, the CR-100 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 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.

Versatile INTERFACE options

The CR-100 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 can be controlled by an Ethernet 10BASE-T/100BASE-TX IEEE-802.3 compliant connection or a RS-232 port.


The CR-100 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.

And lastly, Powerfull 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-100 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.

The Colorimeter Utility is an accompanying tool that aids in updating, preserving and recovering the state of the instrument. It is also used to define a color correction based on the Four-Color Matrix Method Correction.


CIE Tristimulus filter f1' errors

The f1' value, specified in percentage error, represents the degree to which the relative spectral responsivity deviates from the CIE V(λ) curve.

Guaranteed Typical
Y (Photopic) ≤ 2.0% 1.4 – 1.8%
Xr (Red) ≤ 3.0% 2.3 - 2.7%
Xb (Red under Blue) ≤ 1.2% 0.8 - 1.0%
Z (Blue) ≤ 3.5% 2.2 – 2.7%
Each CR-100 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.

Measurement spot size

Spot size at end of hood 23.0 mm
Spot size at 100 mm from end of hood 31.7 mm

The spot size can be calculated at any distance from the end of the rubber hood with the following equation:

Spot size (mm) = 23.0 mm + 0.08732 * distance to object (mm)
