What is an Imaging Colorimeter ?

An imaging colorimeter, such as the UPRtek Imaging Colorimeter,

is a specialized optical device that combines a high-resolution camera with precise photometric filters to measure spatial luminance and color distributions across an image. The device captures detailed data for every pixel, making it ideal for evaluating the uniformity, brightness, and color consistency of displays, LEDs, and lighting systems.

The UPRtek Imaging Colorimeter, is a highly versatile instrument that is widely used in quality control, display testing, and production environments. Unlike spectroradiometer, imaging colorimeters analyse entire surfaces in one capture, making them the most effective solution for high-throughput evaluations.

Imaging Colorimeter vs Spectroradiometer

A spectroradiometer provides precise spectral data and measures light at a single point, ensuring high accuracy in radiometric, photometric, and colorimetric values. It is common practice to use a spectroradiometer as a standard or master for the calibration of other optical measurement instruments, including imaging colorimeters.

 An imaging colorimeter, such as the UPRtek Imaging Colorimeter, captures spatial color and luminance data across an image. It measures multiple points simultaneously, making it suitable for assessing uniformity, defects, and color consistency in displays or large lighting systems. An imaging colorimeter performs better in terms of measuring efficiency and measuring speed.

The key difference is that spectroradiometers specialize in single-point spectral accuracy, whereas imaging colorimeters focus on spatial analysis.

Measurement speed and efficiency are also key differentiators between the two.
