Overview
The Gigahertz Optik LCRT-2005H-S Haze Meter is a portable, spectrally resolved optical measurement instrument engineered for precise determination of haze and total transmittance of transparent and semi-transparent materials. It operates on the principle of d/0° geometry—comprising an integrating sphere source and a luminance detector—fully compliant with ASTM D1003−13 (Standard Test Method for Haze and Luminous Transmittance of Transparent Plastics) and DIN 5036-3 (Optical properties of glass – Determination of haze and light transmission). The system employs dual diode-array spectrometers: one monitors the spectral output of the LED-based illumination source (380–780 nm), while the other characterizes the spectral responsivity of the receiver, ensuring photometric accuracy traceable to the CIE standard observer function V(λ). This dual-spectral architecture enables real-time simulation of illuminants A, C, and D65, as well as accurate correction for ambient light interference via pulsed illumination and automatic background compensation. Designed for field and lab use, the LCRT-2005H-S delivers traceable, repeatable measurements without requiring darkroom conditions.
Key Features
- Integrated d/0° measurement geometry with high-stability integrating sphere source and calibrated luminance detector
- Dual diode-array spectrometers (380–780 nm) for simultaneous spectral monitoring of source output and receiver responsivity
- Real-time ambient light compensation using pulsed LED illumination and background subtraction algorithms
- Manual selectable light trap for compliant haze measurement per ASTM D1005−13 Section 7.3 (specular transmission exclusion)
- Onboard camera-assisted alignment system for rapid source–receiver calibration and sample positioning
- Flexible power options: 4× AA batteries or USB 5 V DC input; ruggedized hard-shell carrying case includes battery storage and accessory compartment
- Integrated spectral simulation engine supporting CIE illuminants A, C, and D65; full compliance with CIE Publication 130 and DIN 5036-3
Sample Compatibility & Compliance
The LCRT-2005H-S is optimized for thin, scratch-sensitive, and optically clear substrates—including automotive glazing, display cover glasses, optical films, polymer sheets, and semiconductor wafers. Its compact d/0° configuration accommodates samples up to 100 mm in thickness when used with optional PMS-RIT mounting fixtures, and supports lateral scanning of large-area specimens via the B2S-40-TRTH rail workstation (1 m track with motorized source/receiver translation). All measurements adhere to internationally recognized metrological frameworks: data traceability aligns with ISO/IEC 17025 requirements for optical testing laboratories; haze values are reported in accordance with ASTM D1003−13 Annex A1 (haze = [diffuse transmittance / total transmittance] × 100%); transmittance results are normalized to the CIE V(λ) photopic luminosity function, ensuring human-vision-relevant quantification. The instrument’s firmware supports GLP-compliant audit trails, including timestamped calibration logs, operator ID fields, and measurement history export (CSV/Excel).
Software & Data Management
The LCRT-2005H-S operates via an embedded touchscreen interface with intuitive workflow-guided menus for transmittance and haze modes. Measurement sequences are fully parameterized—users select illuminant type, integration time, averaging cycles (1–10), and light-trap configuration prior to acquisition. Spectral raw data (source + detector) are stored internally and exportable via USB mass storage mode. Optional PC software (LCRT-Control Suite v3.x) provides advanced post-processing: spectral interpolation, CIE chromaticity coordinate calculation (x,y, u’,v’), Yxy conversion, and comparative spectral overlay across multiple samples. All exported datasets include embedded metadata (instrument ID, calibration date, operator tag, environmental temperature/humidity if logged externally), satisfying FDA 21 CFR Part 11 requirements for electronic records when deployed in regulated QC environments.
Applications
- Automotive: In-line haze verification of laminated windshields, sunroofs, and HUD combiner substrates
- Display Manufacturing: Quality control of cover glass, anti-reflective coatings, and touch sensor films
- Medical Devices: Transmittance validation of optical windows in endoscopic imaging systems and diagnostic cartridges
- Photovoltaics: Characterization of encapsulant clarity and EVA yellowing kinetics under accelerated aging
- Regulatory Testing Labs: Third-party certification per ISO 13468-2 (plastic transparency), JIS K 7136 (Japanese haze standard), and GB/T 2410 (Chinese national standard)
FAQ
What standards does the LCRT-2005H-S comply with for haze measurement?
ASTM D1003−13 (Method A, with manual light trap), DIN 5036-3, ISO 13468-2, and JIS K 7136.
Can the instrument measure both haze and total transmittance simultaneously?
Yes—both parameters are derived from a single spectral acquisition cycle; haze is calculated as the ratio of diffuse-to-total transmittance per ASTM definitions.
Is spectral data export supported?
Yes: full 1 nm-resolution spectra (380–780 nm) from both source and detector are saved in ASCII format and compatible with third-party analysis tools.
How is calibration maintained in field use?
The system includes factory-calibrated reference tiles (certified transmittance standards) and supports user-performed zero/dark calibration and 100% reference normalization before each measurement session.
Does the device support GMP/GLP documentation requirements?
Yes—onboard audit trail logging, operator authentication fields, and CSV export with immutable timestamps meet basic GLP documentation needs; full 21 CFR Part 11 compliance requires optional PC software with digital signature modules.
