This instrument requires a stable, low-vibration environment and a controlled ambient temperature to maintain specified optical performance. The device must be operated within its specified wavelength range and measurement modes to ensure accurate results.
- Environmental Stability: Maintain a stable ambient temperature and avoid direct sunlight or strong air currents to prevent measurement drift.
- Calibration Requirement: Perform periodic calibration using certified reference standards to ensure wavelength and photometric accuracy remain within specified tolerances.
- Sample Surface Condition: Ensure glass samples are clean, free of scratches, and properly positioned to avoid artifacts in transmittance or reflectance measurements.
- Data Integrity: Use the provided software for data acquisition and archiving to maintain traceability and compliance with quality inspection protocols.
This procedure outlines the steps to set up and perform a standard optical measurement. Follow these steps to ensure accurate and repeatable results.
Required Equipment: Atomfair Shading Coefficient Tester, Calibration reference standards, Software interface
- Power On and Warm Up
Turn on the instrument and allow it to warm up for at least 30 minutes to stabilize the light source and detectors. - Perform Baseline Calibration
Run a baseline calibration using the provided software with no sample in the beam path to establish a reference for transmittance and reflectance measurements. - Set Measurement Parameters
Select the appropriate measurement mode (transmittance or reflectance) and set the wavelength range and sampling interval according to the test requirements. - Position the Sample
Place the glass sample securely in the sample holder, ensuring it is perpendicular to the incident beam and free of any obstructions. - Acquire the Measurement
Initiate the scan from the software and wait for the instrument to complete the spectral acquisition across the full wavelength range. - Review and Export Data
Inspect the generated spectral data and calculated parameters, then export the results in the required format for reporting or archiving.
How does the dual-grating and dual-detector configuration affect spectral resolution and measurement accuracy across the UV-Vis and NIR ranges?
The Atomfair tester employs a UV/VIS grating of 1200L/mm and a NIR grating of 300L/mm, coupled with a PMT detector for UV-Vis and a PbS detector for NIR. This yields a spectral bandwidth of 1.5nm in the 300-1100nm range and 2.5nm in the 1100-2500nm range, optimizing resolution in the visible while maintaining wide coverage in the infrared. Wavelength accuracy is ≤±0.3nm in the 360-900nm band and ≤±1nm in the 900-2500nm band, ensuring reliable shading coefficient calculations.
What types of glass can the Atomfair Shading Coefficient Tester evaluate, and what modes are available?
The tester is designed for architectural flat glass, coated glass, Low-E energy-saving glass, insulated glass, automotive safety glass, and photovoltaic glass. It supports both transmittance and reflectance measurement modes, enabling comprehensive evaluation of shading coefficient, visible light transmittance, direct solar transmittance, and ultraviolet transmittance in a single instrument.
Is the Atomfair Shading Coefficient Tester suitable for on-site field measurements, and what are its physical requirements?
With dimensions of 730mm × 650mm × 260mm and a weight of 28 kg, the tester is designed with a rugged body structure for both laboratory fixed detection and on-site mobile sampling inspection. It connects via USB2.0 to a Windows PC (7, 8, 10, or XP) and does not require specialized training to operate, though a stable, level surface is recommended for accurate measurements.
The Atomfair Architectural Glass Shading Coefficient Tester integrates dual-mode transmittance/reflectance measurement with full-spectrum 300–2500 nm scanning, enabling direct determination of shading coefficient and related optical-thermal parameters for architectural, photovoltaic, and automotive glass. Its dual-grating PMT/PbS receiver design and low stray light specifications support high-precision laboratory and on-site quality assessment, though the 28 kg benchtop form factor and Windows-only software impose infrastructure and portability constraints.
Positive
- Full-spectrum dual-mode measurement: Covers 300–2500 nm with both transmittance and reflectance modes, enabling simultaneous determination of shading coefficient, visible light transmittance, and solar optical properties in a single instrument without additional equipment.
- High spectral and photometric precision: Wavelength accuracy of ≤±0.3 nm (360–900 nm) and photometric repeatability of ≤0.2%τ, combined with stray light as low as ≤0.05%τ (400–2500 nm), ensure reliable data for international-standard compliance testing.
Trade-offs
- Benchtop form factor limits portability: Weighing 28 kg with dimensions of 730×650×260 mm, the instrument is designed for fixed laboratory use; on-site mobile sampling requires additional handling and stable support surfaces.
- Windows-only software dependency: Data interface and supported systems are limited to Windows XP/7/8/10 via USB 2.0/3.0, requiring a compatible PC and potentially restricting integration with non-Windows laboratory data systems.
