Sample dimensions must be 20–100 mm in width and no more than 20 mm thick. The instrument requires a 30-minute warm-up period after power-on to achieve baseline flatness of ±0.005 A over 200–2500 nm.
- Sample Compatibility: The tester is designed for transparent, insulating, and coated architectural glass within the specified size limits.
- Infrastructure Requirements: A computer with the provided software and a USB2.0 interface is necessary for instrument control and data acquisition.
- Calibration Procedure: Automatic calibration must be performed at startup to ensure measurement accuracy per ISO 9050-2003.
- Spectral Bandwidth Adjustment: UV-VIS bandwidth can be set to any of seven discrete values from 0.1 to 5.0 nm, while NIR bandwidth is adjustable from 0.4 to 16.0 nm automatically or manually.

How does the dual-beam dual-detector optical system improve measurement accuracy for low-transmittance coated glass?
The dual-beam, dual-grating, dual-detector configuration effectively reduces background interference, which is critical for low-transmittance samples. Combined with a stray light of ≤0.2%T at 220nm and baseline flatness of ±0.005A after 30 minutes warm-up, the system achieves a transmittance accuracy of ±0.3%T and repeatability ≤0.2%T. This ensures reliable data even for heavily coated or tinted architectural glass.
Can the Atomfair-GL-629 directly measure the solar heat gain coefficient (SHGC) or only the shading coefficient?
The instrument measures total solar energy transmittance and shading coefficient as defined by ISO 9050-2003. While SHGC is not explicitly listed as an output parameter, the shading coefficient is directly related and can be used to derive SHGC per standard procedures. The sample size must be 20-100mm with thickness ≤20mm; the optional integrating sphere (280-2500nm) extends diffuse measurement capability for textured or patterned glass.
What warm-up and environmental conditions are required to achieve the specified baseline flatness and wavelength accuracy?
The baseline flatness of ±0.005A over 200-2500nm is guaranteed only after a 30-minute warm-up. The instrument requires AC220V, 50Hz power and operates within standard laboratory conditions. Wavelength accuracy is ±0.5nm in UV/VIS and ±2.0nm in NIR, with repeatability ≤0.3nm and ≤1.0nm respectively. The sample chamber dimensions (120×240×200mm) accommodate glass up to 20mm thick, and the 65kg unit should be placed on a stable, vibration-free bench.
The Atomfair-GL-629 is a dual-beam, dual-grating, dual-detector spectrophotometer engineered for ISO 9050-2003 energy-saving assessment of architectural glass, delivering ±0.3%T transmittance accuracy across 190-3200nm with a 5-minute full scan. Its 20-100mm sample chamber and optional integrating sphere support direct optical and thermal parameter measurement for QC, engineering, and research applications.
Positive
- High-precision dual-beam optical system: The dual-beam, dual-grating, dual-detector design minimizes background interference, achieving ±0.3%T transmittance accuracy and ≤0.2%T repeatability, which is critical for reliable ISO 9050-2003 energy performance classification.
- Broad spectral and sample versatility: Covering 190-3200nm with adjustable spectral bandwidth (UV-VIS 0.1-5.0nm; NIR 0.4-16.0nm) and supporting 20-100mm samples up to 20mm thick, the instrument accommodates transparent, insulating, and coated glass types for diverse QC and R&D workflows.
Trade-offs
- Requires 30-minute warm-up for baseline flatness: Baseline flatness of ±0.005A is only guaranteed after a 30-minute warm-up, which extends pre-test stabilization time and may affect high-throughput batch testing schedules.
- Fixed AC220V/50Hz power and 65kg weight: The instrument operates solely on AC220V/50Hz and weighs 65kg, requiring dedicated bench space and stable power infrastructure, which may limit portability or deployment in field-based testing environments.
