This article explains how the Agera L2’s embedded camera strengthens quality control by allowing operators to visually confirm sample alignment, detect surface irregularities, and document appearance. By pairing visual evidence with spectral and colorimetric data, the system improves measurement reliability, ensures traceability across batches, and supports both internal quality workflows and customer reporting requirements. The purpose of the imaging system is to provide a more complete representation of each measurement—significantly reducing errors, eliminating misreads, and enabling higher confidence in pass/fail decisions.
Image Capture Occurs Automatically: The camera records the sample area during measurement; no additional steps are required by the operator.
Images Are Stored With Data: Captured images can be saved, exported, and included in audit trails, reports, and quality records.
Visual + Numeric Data Improve Correlation: Image-assisted measurement ensures that the recorded color values correspond to the exact sample region analyzed.
The HunterLab Agera L2 incorporates a high-resolution integrated imaging system designed to elevate the accuracy, traceability, and confidence of every color measurement. Unlike conventional spectrophotometers that rely solely on numeric outputs, the Agera L2 captures a real-time image of the sample surface in the measurement area, providing operators with immediate visual confirmation before, during, and after each reading.
Real-Time Visual Verification
At the moment of measurement, the embedded camera records a high-clarity image of the sample area. This enables users to:
- Confirm that the sample fully covers the port.
- Verify that the correct region of interest is being measured.
- Detect any misalignment, tilt, foreign particles, or operator-induced errors.
This real-time visual check reduces rework, prevents mismeasurements, and ensures that the obtained data truly corresponds to the intended surface.
Enhanced Quality Assurance
Surface conditions such as contamination, gloss variation, texture inconsistency, or irregular sample geometry can influence color results. The Agera L2 imaging system helps identify these issues before they compromise measurements. Operators can quickly spot:
- Contamination such as fibers, dust, or fingerprints
- Uneven sample surfaces or texture defects
- Air bubbles in liquids
- Particulate variability in powders or granules
By detecting these factors immediately, the imaging feature strengthens process control and minimizes sources of measurement variability.
Image Documentation for Traceability
Every captured image can be linked to its corresponding color data record. These image files provide:
- Clear visual evidence to accompany reported values
- Stronger documentation for audits and ISO compliance
- Reliable batch-to-batch and lot-to-lot comparison
- Supporting material for customer quality assurance reports
This combination of visual and numerical data creates a deeper, more transparent record of product appearance—ideal for industries requiring full traceability, including plastics, food, paint, packaging, pharmaceuticals, and cosmetics.
Improved Confidence and Accuracy
By combining high-resolution imaging with advanced spectrophotometric measurement, the Agera L2 ensures that:
- Each measurement is associated with the correct sample location
- Potential anomalies are identified before data is accepted
- Visual inspection and colorimetric evaluation occur simultaneously
- Operators gain confidence in both the measured values and the condition of the sample
The imaging system effectively closes the gap between visual inspection and instrumental analysis, producing a complete and validated assessment of color and appearance.
