Jianhu JH-2026 Transmittance and Haze Analyzer

Overview

The Jianhu JH-2026 Transmittance and Haze Analyzer is a benchtop optical property testing instrument engineered for precision measurement of total transmittance (%T), diffuse transmittance, and haze (%) in transparent and semi-transparent materials. Based on the principle of collimated beam transmission and integrating sphere detection (per ISO 13468-1 and ASTM D1003), the system employs a stabilized tungsten-halogen light source (380–780 nm, CIE Illuminant A), dual-channel photodetectors, and a 150 mm diameter integrating sphere with BaSO₄-coated interior walls to ensure high signal-to-noise ratio and spectral uniformity. Designed specifically for industrial QA/QC environments—including glass fabrication lines, display module assembly, automotive glazing production, and optical film manufacturing—the JH-2026 delivers repeatable, traceable results under demanding conditions: continuous 168-hour operation, ambient particulate exposure (tested per IP54-equivalent dust simulation), and multi-material throughput without recalibration.

Key Features

• Optical accuracy: ±0.3% absolute error for transmittance (0–100%), ±0.1% for haze (0–30%)—validated against NIST-traceable standard reference materials (SRMs)
• Robust mechanical architecture: Powder-coated steel chassis with sealed optical path, fan-cooled thermal management, and vibration-damped base plate for factory-floor stability
• Adaptive sampling interface: Adjustable sample holder accommodating thicknesses from 0.1 mm to 50 mm; optional motorized stage for automated batch measurement
• Configurable measurement speed: User-selectable integration time (10–500 ms) and averaging cycles (1–99) to balance throughput and signal fidelity across production line speeds
• Self-diagnostic firmware: Real-time lamp intensity monitoring, sphere wall reflectance drift compensation, and automatic zero/reference calibration prompts
• Compliance-ready operation: Built-in audit trail logging, user access levels (admin/operator), and timestamped result export—supporting GLP/GMP documentation requirements

Sample Compatibility & Compliance

The JH-2026 supports flat, rigid, or flexible specimens up to 120 × 120 mm, including float glass, tempered automotive laminates, PET/PC films, AR-coated optics, OLED encapsulation layers, and medical-grade polymers. It meets key international standards for optical clarity assessment: ISO 13468-1 (plastics — determination of transmittance), ISO 14782 (determination of haze for transparent plastics), ASTM D1003 (standard test method for haze and luminous transmittance), and Chinese national standard GB/T 2410. All units undergo three-stage factory validation: (1) SRM-based photometric calibration using certified glass standards (e.g., NIST SRM 931b analogs); (2) 72-hour continuous operational stress test under simulated factory thermal and particulate load; (3) dust ingress resistance verification per IEC 60529 IP54 methodology. Each instrument ships with a Certificate of Conformance and calibration report traceable to China National Institute of Metrology (CNIM).

Software & Data Management

The embedded JH-Link™ software (v4.2, Windows 10/11 compatible) provides full control via touchscreen or remote PC interface. It enables real-time spectral visualization, statistical process control (SPC) charting (X̄-R, Cp/Cpk), and customizable report generation (PDF/CSV/XLSX) with embedded metadata (operator ID, timestamp, environmental temp/humidity, instrument serial). Data export supports direct integration into MES/ERP platforms via OPC UA or Modbus TCP protocols. For regulated environments, optional 21 CFR Part 11 compliance package includes electronic signatures, role-based permissions, immutable audit logs, and encrypted database storage. Firmware updates are delivered via secure HTTPS channel with SHA-256 signature verification.

Applications

• Automotive: In-line haze verification of laminated windshields and HUD combiner substrates
• Display manufacturing: Quantitative pass/fail screening of cover glass, touch sensor films, and polarizer stacks
• Pharmaceutical packaging: Clarity assessment of blister foil lidding and polymer vial materials per USP
• Optics & photonics: Batch qualification of AR/HR coatings, laser window substrates, and fiber optic collimator assemblies
• Renewable energy: Transmittance uniformity mapping of PV encapsulant sheets and anti-soiling coated solar glass

FAQ

What standards does the JH-2026 comply with for regulatory submissions?

It conforms to ISO 13468-1, ISO 14782, ASTM D1003, GB/T 2410, and JJG 696—fully supporting validation protocols required by FDA, EMA, and NMPA for optical component release.
Can the instrument be integrated into an automated production line?

Yes—via digital I/O triggers, RS-232/485, or Ethernet/IP, enabling start/stop synchronization with conveyor systems and PLCs.
Is third-party calibration available?

Jianhu partners with CNAS-accredited labs (e.g., SGS Shanghai, CCIC Shanghai) for annual accredited calibration; certificates include uncertainty budgets per ISO/IEC 17025.
What is the warranty and service coverage?

Three-year comprehensive warranty, including parts and labor; 38 authorized service centers across Greater China provide 24-hour onsite response for critical failures.
Does it support measurement of curved or textured surfaces?

Flat-sample geometry is required per ASTM D1003; for non-planar optics, optional custom fixtures (e.g., concave sample holders) are available upon engineering review.
