Spectroradiometers for Accurate Display Measurement and Characterisation
Spectroradiometers for Accurate Display Measurement and CharacterisationSpectroradiometers are the preferred reference instruments for measuring the optical performance of modern displays. By analysing the spectral output of a display, they provide highly accurate measurements of luminance, chromaticity, colour gamut, white point, correlated colour temperature, and other critical display performance parameters.
Used throughout display research, development, manufacturing, and quality assurance, spectroradiometers deliver the precision required to evaluate and optimise display performance across a wide range of technologies, including LCD, OLED, MiniLED, MicroLED, automotive displays, medical displays, and AR/VR devices.
Typical display measurement applications include:
- Display luminance measurement
- Colour and chromaticity analysis
- White point verification
- Colour gamut evaluation
- HDR display testing
- Display calibration
- Uniformity assessment
- Production quality control
- Compliance and standards-based testing
Konica Minolta Spectroradiometers
Konica Minolta spectroradiometers are regarded as industry benchmarks for display metrology and colour measurement. Widely used by display manufacturers, research laboratories, and quality assurance teams worldwide, instruments such as the CS-2000 Plus and CS-3000 Series provide the accuracy, repeatability, and reliability required for advanced display characterisation.
These instruments are particularly well suited to demanding applications involving HDR displays, OLEDs, MicroLEDs, automotive displays, and next-generation display technologies.
