Technology Highlights
What makes Agera L2 “reference-grade” is not one feature alone, but the integration of true CIE-calibrated D65 daylight, enhanced low-reflectance performance, a significantly expanded area of view, intelligent embedded computing, and an optical architecture designed for years of stable operation. Together, these capabilities provide unmatched ability to measure color the way it is seen—accurately, consistently, and repeatably.
CIE Calibrated D65 Source Illumination
Illumination is the foundation of color measurement.
Agera L2 introduces CIE-calibrated TrueD65 illumination with controlled, calibrated UV—something most instruments only approximate. By reproducing the full visible and UV structure of D65 with precision, Agera L2 ensures that instrumental color measurements align with what is seen in simulated daylight, such as a lighting booth, and under natural daylight conditions. The result is greater confidence, consistency, and global correlation, reducing rework and approval delays. With TrueD65, visual and instrumental agreement becomes reliably dependable.
Precise Near UV Measurement
Ultraviolet (UV) energy is an integral part of natural daylight, and the Agera L2 accurately captures the visible-excited fluorescence—the characteristic glow emitted by bright whites, optical brightening agents (OBAs), and safety colors when illuminated by UV light—as it truly appears in real-world viewing conditions. The result is color data that correlates seamlessly between the laboratory, the daylight viewing booth, and the retail environment. This verified daylight and UV fidelity ensures color confidence, tighter supplier alignment, and fewer discrepancies across the supply chain.
Ultra Dark Mode
Many manufacturing environments involve materials with inherently low reflectance—deep chromatic plastics, low-gloss coatings, masterbatch, elastomers, specialty inks, and carbon-loaded compounds.
Ultra Dark Mode expands Agera L2’s capabilities into the lowest reflectance ranges, enabling accurate, stable color measurement of deep blacks, navies, and saturated pigments that challenge conventional instruments. Ultra Dark Mode automatically optimizes illumination and integration to enhance signal-to-noise ratio, ensuring repeatable, trustworthy color data even for the darkest materials.

0°/45°c Circumferential geometry
The HunterLab Agera L2 employs 0°/45°c Circumferential geometry, the industry’s most visually correlated configuration for measuring color as the human eye perceives it. In this geometry, the sample is illuminated perpendicularly at 0° while reflected light is collected at 45° by 15 optical sensors from a full 360° circle around the sample. This design eliminates directional bias caused by surface texture, gloss, or grain orientation—ensuring that the measured color matches what an observer sees.
Largest Measured Area in Its Class
Agera L2 measures 4× more surface area than typical benchtop instruments, reducing the effect of texture, grain, directionality, and pattern variation. Large, textured, or patterned samples—WPCs, engineering plastics, coated metals, granites, textiles—can shift color dramatically when measured through a tiny aperture. Agera L2 captures more of the surface, delivering truer averages and higher Sigma repeatability.
Integrated 60° Gloss
Gloss dramatically affects how color is perceived. The Agera L2 features an integrated 60° gloss meter, conforming to international standards ASTM D523 and ISO 2813. 60-degree gloss is the default universal angle most widely used for plastics and general industrial surfaces. With the Agera L2 you don’t just get separate color and gloss readings—you get simultaneous acquisition of reflectance color (0°/45° geometry) and 60° gloss in the same measurement event. This means that gloss is recorded and tied to the color data. The result?: fewer second-guesses, faster approval cycles, and better global alignment of appearance across suppliers, plants and brands.
High Resolution Imaging
The HunterLab Agera L2 features an integrated high-resolution imaging system that provides real-time visual confirmation of every measurement. This advanced system is built around a 2592 × 1944 (5 MP) active-array sensor with a 1/4" optical format and 1.4 µm × 1.4 µm pixel size, delivering crisp detail and exceptional clarity and consistent, reliable imaging even on dark, matte, or low-reflectance materials. Automatic exposure control, auto white balance, automatic black-level calibration, and LED/flash-strobe support ensure that every captured image is accurately lit and visually consistent across material types, operators, and environment, allowing users to verify proper sample positioning, detect contamination or texture irregularities, and document visual appearance alongside numeric color data.
