According to the recommendation in the Information Display Measurement Standard (IDMS Chapter A4.1), in standard display measurements, a measurement spot size that covers at least 500 pixels is typically selected.

The Prometheus Viewfinder Spectrometer, equipped with a standard lens, delivers excellent performance and versatility, meeting almost all needs for high-precision spectral spot display measurements. By selecting an appropriate measurement distance, it ensures that the required number of pixels are measured.
