The Atomfair-GL-794 requires a 30-minute warm-up to achieve baseline flatness within ±0.005A over 200-2500nm. Sample dimensions must be between 20-100mm with thickness ≤20mm to fit the sample chamber.
- Preheating Requirement: The instrument must be warmed up for at least 30 minutes prior to measurement to achieve baseline flatness within ±0.005A over 200-2500nm.
- Sample Size Constraint: The glass sample must have dimensions between 20-100mm and thickness no greater than 20mm to fit the sample chamber.
- Wavelength Calibration: Wavelength accuracy is maintained at ±0.5nm in the UV/Vis range and ±2.0nm in the NIR range after proper calibration.
- Working Mode Selection: Measurements can be performed in transmission or reflection mode, with an optional integrating sphere accessory for diffuse measurements.
The Atomfair-GL-794 measures optical and thermal parameters of architectural glass samples. Follow these steps to perform a standard measurement.
Required Equipment: Atomfair-GL-794 main unit, Transmission accessory, Specular reflection accessory, Standard reflector
- Warm up instrument
Allow the instrument to warm up for 30 minutes after powering on to stabilize the baseline. - Prepare sample
Place the glass sample in the sample chamber, ensuring dimensions are within 20-100mm and thickness ≤20mm. - Set parameters
Set the working mode (transmission or reflection) and spectral bandwidth via the software interface. - Calibrate instrument
Initiate automatic instrument reset and baseline calibration using the software. - Run measurement
Start the spectral scan, which takes approximately 5 minutes for a full range measurement. - Process data
Use the software to view, export, or print the spectral data and calculated parameters.
How does the stray light specification of ≤0.2%T at 220nm affect the accuracy of solar transmittance measurements for spectrally selective architectural glass?
The Atomfair-GL-794 achieves stray light ≤0.2%T at 220nm, which is critical for accurate solar transmittance measurements because stray light can artificially inflate transmittance values for UV-blocking or spectrally selective coatings. This level meets the requirements of ISO 9050-2003 and ensures that direct solar transmittance and shading coefficient data are reliable for energy performance evaluation.
Can the Atomfair-GL-794 measure full-size architectural glass panels without sample cutting?
No. The sample chamber has internal dimensions of 120×240×200mm, so glass samples must be cut to a maximum size of 100mm in length/width and ≤20mm thickness. The instrument is designed for coupon-scale testing typical of quality control and compliance verification, not for full-pane measurement.
What are the power and warm-up requirements for installing the Atomfair-GL-794 in a research laboratory?
The instrument requires AC220V, 50Hz power supply and weighs 65kg with dimensions 750×600×260mm. A 30-minute warm-up is required to achieve baseline flatness of ±0.005A (200-2500nm). The source does not specify additional environmental controls, but stable power and a vibration-free bench are recommended for optimal optical precision.
The Atomfair-GL-794 is a dual-beam, dual-grating spectrophotometer engineered for ISO 9050-2003 compliance testing of architectural glass, delivering high-accuracy optical and thermal parameters across a 190-3200nm range. Its imported light source and dual detectors ensure low-noise, stable measurements, while the 20-100mm sample chamber and optional integrating sphere extend its utility for diverse glass types and research applications.
Positive
- High-precision dual-beam optics: The dual-beam, dual-grating, dual-detector system minimizes background interference, achieving wavelength accuracy of ±0.5nm (UV/VIS) and ±2.0nm (NIR), with transmittance accuracy of ±0.3%T and repeatability ≤0.2%T, ensuring reliable data for energy-saving glass evaluation.
- Broad spectral and sample versatility: Covering 190-3200nm with adjustable bandwidth (UV-VIS: 0.1-5.0nm; NIR: 0.4-16.0nm) and supporting samples 20-100mm (thickness ≤20mm), the instrument accommodates various glass types including coated and insulating glass, with an optional integrating sphere for expanded measurement capabilities.
Trade-offs
- Requires 30-minute warm-up for baseline stability: Baseline flatness of ±0.005A is specified only after a 30-minute warm-up, meaning users must factor in this stabilization period before achieving optimal measurement accuracy, which may impact workflow scheduling in high-throughput testing environments.
- Sample size and power constraints: The instrument accepts samples only within 20-100mm and thickness ≤20mm, limiting use for larger or thicker glass panels. Additionally, it requires AC220V, 50Hz power, which may not be compatible with all laboratory electrical infrastructures without voltage conversion.
