Product catalog summary
Overview: The 2D Color Analyzer CA-2500 is a device designed for evaluating display nonuniformity (mura) on devices such as smartphones and tablets. It provides accurate measurements of luminance and chromaticity distribution.
Key Specifications:
  • Expanded low-luminance measurement range from 0.1 cd/m2 to 0.05 cd/m2.
  • Enhanced durability with a service life five times longer than the CA-2000.
  • Comprehensive factory calibration ensures high-accuracy measurements without limitations on method, size, or brightness.
  • Interchangeable lenses (standard, wide-angle, telephoto) for various subjects and measurement areas.
  • XYZ filters for high correlation with human eye spectral response.
Applications:
  • Simultaneous luminance/chromaticity distribution measurement of multiple small or medium-sized LCD or organic EL panels.
  • Luminance/chromaticity measurement of single large-sized LCD or organic EL panels.
  • Display mura evaluation and luminance distribution measurements in illumination fields.
  • Measurements of automobile instrument panel meters and projector screen images.
Software and Features:
  • Data Management Software CA-S25w includes focus assist, positioning assist, and automatic measurement area extraction.
  • Optional Mura Evaluation Software for evaluating display mura using original index values.
  • SDK available for custom software development, including Labview® support.
System Requirements:
  • Compatible with Windows® 10 Pro and Windows® 11 Pro.
  • Requires a Pentium® 4 2.8 GHz equivalent CPU, 1,024 MB memory, and specific hard disk space for calibration data.
  • Display capable of at least 1,280 x 768 dots / 65,536 colors.
Environmental Considerations:
  • Recommended usage and storage under standard conditions (23°C, 40% RH).
  • Regular inspections recommended to maintain measurement accuracy.
  • Long-term exposure to high temperature/humidity may affect accuracy.
Main Specifications: The CA-2500 series includes models CA-2500S, CA-2500W, and CA-2500T, utilizing a CCD image sensor with a resolution of 1,000 x 1,000 pixels and equipped with XYZ and ND filters. Interchangeable lenses offer standard, wide, and telephoto options, along with macro rings for varying magnifications.
Measurement Capabilities: Measurement points can be adjusted to 980 x 980, 490 x 490, or 196 x 196 using the Data Management Software CA-S25w. The devices support various color indication modes such as XYZ, Lvxy, and Lvu’v’. Display modes include pseudocolor, chromaticity diagram, and color difference.
Measurement Sizes and Distances: Measurement sizes vary depending on the lens and distance, with fixed sizes for macro rings. The measurable luminance range is from 0.05 to 100,000 cd/m2, with measurement times ranging from 5 seconds to 80 seconds depending on integration.
Accuracy and Repeatability: Luminance accuracy is ±3%, and chromaticity accuracy is ±0.005. Temperature and humidity can affect measurements, with specified drift values. Repeatability for luminance is 0.5%, and for chromaticity, it is 0.001.
Environmental Conditions: The operating temperature range is 10-30°C with a relative humidity of 70% or less. Storage conditions allow for a temperature range of 0-35°C with varying humidity limits.
Physical Specifications: The device dimensions are 160 (W) × 164 (H) × 192 (D) mm, with a weight of approximately 3.5 kg when equipped with a standard lens and hood. Power is supplied via an AC adapter.
Safety and Certifications: Users are advised to read the instruction manual for safe operation. The device must be connected to the specified power supply to prevent hazards. Konica Minolta's Sakai site holds ISO certifications for design, development, and service of measuring instruments.

2D Color Analyzer CA-2500 Comprehensive factory calibration XYZ filters provide high correlation with the spectral response of the human eye. Instead of the RGB color-separation filters used by digital video cameras, etc., the CA-2500 uses XYZ filters that closely match the CIE 1931 color-matching functions to provide luminance and chromaticity measurements that have high correlation with the spectral response of the human eye. CIE1931_X2 Relative sensitivity Even flickering light sources such as OLED televisions or PDP can be measured with good accuracy. The synchronization frequency (4 to 2,000...
