Tristimulus Colorimeter / Photometer

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.


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.

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-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.

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.


Viewing system options

The Detachable Viewing System (Patent pending)

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 Rotatable Viewing Systems (Patent pending)

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.

The Perpendicular Viewing System:

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 Camera Viewing System

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.

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-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.
