This article explains why dark and low-reflectance materials are difficult to measure accurately and how Agera L2 Dark Performance Mode improves repeatability and confidence when measuring these challenging samples. Using real measurement data, it shows how Dark Performance Mode reduces noise, improves stability, and delivers more reliable color results—supporting tighter tolerances, fewer false rejects, and better process control across a wide range of applications.
Important Notes:
Dark Performance Mode is a dedicated measurement mode designed for dark materials
Dark Performance Mode is not software averaging or post-processing. It is a purpose-built measurement mode within Agera L2 that optimizes illumination, detection, and signal handling to improve accuracy and repeatability on dark and low-reflectance samples.Improved performance comes from system optimization—not illumination alone
While Agera L2 uses CIE-calibrated D65 LED illumination, this article shows that illumination source by itself does not determine dark-color performance. Reliable results on ultra-dark materials require noise reduction, optical optimization, and proper detector handling across the entire measurement system.Benefits extend beyond near-black materials
Although the largest gains occur on very dark samples, Dark Performance Mode also improves measurement stability on mid-tone materials. This helps preserve tolerance limits, improves SPC performance, and reduces false variation in demanding production environments.
