Overview
The 3nh YL4560 Non-Contact Desktop Online Spectrophotometric Color Difference Meter is a precision optical measurement instrument engineered for high-reproducibility color evaluation under controlled laboratory and industrial environments. It operates on the internationally recognized 45°/0° illumination/viewing geometry—defined by CIE Publication No. 15 and compliant with ISO 7724-1, ASTM E308, and DIN 5033-7—where a ring-shaped array of xenon flash lamps delivers uniform 45° circumferential illumination, while a single central spectrometer collects reflected light at 0° normal incidence. This configuration minimizes directional reflectance artifacts and eliminates specular highlight interference, making it especially suitable for matte, textured, or semi-gloss surfaces. Unlike contact-based integrating sphere instruments, the YL4560 employs a fixed-focus optical probe with adjustable working distance (standard 10–25 mm), enabling true non-contact measurement of fragile, thermally sensitive, or hygienically critical samples—including liquids, pastes, powders, gels, and coated substrates—without risk of contamination or mechanical deformation.
Key Features
- Non-contact scanning architecture with stable focal depth and auto-triggered acquisition, eliminating operator-induced positioning error.
- Xenon pulsed light source ensures consistent spectral power distribution across 360–780 nm, with minimal thermal drift and no warm-up delay—critical for high-throughput QC workflows.
- High-resolution CCD linear array spectrometer with thermoelectric cooling enables low-noise spectral acquisition and long-term photometric stability.
- Integrated real-time ΔE*ab calculation engine supports CIE 1976 L*a*b*, CIE L*C*h°, XYZ, Yxy, and Hunter Lab color spaces, with selectable illuminants (D65, A, C, F2, F7, F11) and standard observers (2° and 10°).
- Designed for both benchtop R&D use and inline integration: features RS-232, USB 2.0, and optional Ethernet (TCP/IP) interfaces for seamless PLC or MES system communication.
- Complies with GLP documentation requirements via embedded audit trail logging (user ID, timestamp, instrument ID, measurement parameters, raw spectrum data) in accordance with FDA 21 CFR Part 11 readiness guidelines.
Sample Compatibility & Compliance
The YL4560 accommodates heterogeneous sample forms without physical contact: free-flowing powders (e.g., pigments, pharmaceutical excipients), viscous suspensions (cosmetic emulsions, food sauces), transparent or translucent liquids (beverages, solvents), and delicate films (electronic display filters, biomedical membranes). Its 45°/0° geometry inherently suppresses specularity, allowing accurate measurement of fluorescent materials under UV-augmented D65 simulation—validated per ISO 11664-7 and CIE Technical Report 214. The instrument meets CE marking requirements for electromagnetic compatibility (EN 61326-1) and safety (EN 61010-1), and its firmware architecture supports traceable calibration using NIST-traceable ceramic tile standards (certified SRM 2036, 2037).
Software & Data Management
The included PC software—ColorExpert v4.x—provides full spectral data visualization, batch statistical analysis (CPK, X-bar/R charts), tolerance setting (ellipsoidal, rectangular, or custom Munsell-based), and automated report generation (PDF/CSV/XLSX). All raw spectral scans are stored with metadata tags (operator, date, location, sample ID), supporting retrospective root-cause analysis during quality investigations. Data export conforms to ASTM E2892-13 for color data interchange, and the software includes role-based access control (administrator, technician, viewer) to enforce procedural integrity in regulated environments.
Applications
The YL4560 serves as a reference-grade color verification tool across industries governed by strict chromatic consistency requirements: formulation labs in cosmetics (foundation shade matching), food QA (fruit pulp browning index, sauce hue stability), pharmaceuticals (tablet coating uniformity per USP ), electronics (OLED panel white point tracking), and automotive coatings (multi-layer paint film metamerism assessment). In continuous manufacturing settings, it interfaces directly with SCADA systems to trigger alarms when ΔE*ab exceeds user-defined thresholds—enabling closed-loop process correction before off-spec material accumulates.
FAQ
Does the YL4560 require annual recalibration?
Yes—recommended annually using certified reference tiles; field verification with zero and white calibration checks should be performed before each measurement session.
Can it measure transparent liquids in cuvettes?
Yes, when used with optional transmission adapter and matched quartz cuvettes (10 mm path length); spectral transmittance mode supports CIE TCI and YI E313 calculations.
Is fluorescence compensation supported?
Yes—the xenon source includes UV component (360–400 nm), and software applies built-in fluorescence correction algorithms per ISO 11664-7 Annex B.
What is the minimum measurable sample area?
30 mm diameter at 20 mm working distance; smaller areas may be measured with optional 10-mm aperture mask.
Does it support Good Manufacturing Practice (GMP) documentation?
Yes—full electronic record retention, user authentication, and change history logging meet ALCOA+ principles for regulated color release testing.
