Chroma 2D Color Analyzer 71803 Series is equipped with a high-resolution scientific-grade camera and uses Thermoelectrically Cooled (TEC) CMOS with precision optical components and circuit design to provide accurate, fast, and highly repeatable measurements. Combined with the CIEmatching and ND filters, the analyzers produce measurement results that closely correspond with real human perception, suitable for measuring the chromaticity, luminance, contrast, uniformity, and correlated color temperature (CCT) of various kinds of displays.
The 71803 series offers complete control and analysis software required for optical measurement, with intuitive setting and measurement control as well as detailed image data evaluation and analysis, including camera operation parameters, exposure time, and pixel binning. CIE chromaticity diagrams for color analysis and real color simulation functionality are also provided. Furthermore, users can manually calibrate the instruments to factory standards with the calibration function.
In terms of image quality, the Color Analyzer 71803 uses a high-resolution camera to measure 2D chromaticity and luminance, particularly suitable for applications that require speed and large numbers of measurement points, such as flat panel display uniformity and LED/Mini LED backlight die defects testing. With the included standalone software, the user can set any number of points of interest according to the application's requirements. The software can obtain the chrominance and luminance of each point independently, detect abnormalities of each light-emitting element such as defects, color difference, and color cast, and additionally supports the measurement of the DUT's uniformity and contrast. After the DUT's image has been captured, it can be analyzed for various items in user-specified regions of interest. Last but not least, the built-in ANSI specification 5/9/13 point measurement further helps to improve operation convenience and efficiency.
To achieve an even faster color and optical test solution, the CoaXpress ultra-high-speed signal interface is used for transmission at data rates up to 6.25 Gb/s, or even rates as high as 25 Gb/s when using four-wire simultaneous transmission, providing high-resolution image transmission that is both fast and stable.
Users can select from a variety of image quality inspection software for different industries and test applications. The provided optical measurement Software Development Kit enables rapid design of suitable test programs to meet the needs of high-volume manufacturing inspection applications in the display, backlight module, and AR/VR industries.

CIE Chromaticity Diagram
CIE chromaticity diagrams enable accurate simulation of real color values. The calibration function lets the user perform traceability calibration of standard factory equipment.
High-speed Image Transmission Interface
In order to achieve an even faster color optical test solution, the CoaXpress ultra-high-speed signal interface is used for transmission at data rates up to 6.25 Gb/s, or even rates as high as 25 Gb/s when using four-wire simultaneous transmission, providing both fast and stable high-resolution image transmission.
Optics Master System Software
Chroma 71803 2D Color Analyzer features optical measurement software that enables the user to set any number of regions of interest (ROI) depending on the requirements of the application. The software can obtain the chromaticity and luminance of each region independently, and can detect defects, chromatic aberration and color shifts.
Measurement interface
The convenient home screen displays individual measurement items, a measurement item list and results statistics, and allows real-time viewing of the state of the DUT.
Instant display
The real-time imaging function enables the user to measure focus and field of view, and verify the DUT. The camera can continuously capture images according to the defined exposure time.
Regions of Interest (ROI) Definition
Users can set the Regions of Interest (ROI) and scan position with the included software. The edit function can automatically track these regions, and allows editing of the steps of successive measurements.
Calibration Functionality
After modifying the DUT, the user can perform calibrations of the intensity and color ratio of the DUT, and adjust the calibration according to the focal length of the lens in order to obtain the best image quality during measurement.
Application Range
Televisions, tablets, monitors, automotive, VR/AR, camera monitors, medical equipment, wearable devices, outdoor displays, and other imaging products.
