Overview
The AELAB AE-SP4000 Series Double-Beam UV-Visible Spectrophotometer is engineered for high-stability optical measurement, supporting absorbance, transmittance, reflectance, and energy testing for laboratory analysis and industrial quality control. The AE-SP4000 uses ARM microcomputer control with advanced signal processing to maintain reproducibility, data integrity, and reliable UV-Visible spectrophotometry.
The AELAB AE-SP4000 double-beam UV-Visible spectrophotometer integrates USB data export, Bluetooth functionality, and CSV reporting to support GLP-aligned documentation. With a high-resolution C-T structure monochromator and a precision optical platform, the AE-SP4000 stabilizes wavelength accuracy, reduces drift, and improves long-term measurement consistency.
⚙️ Design & Construction
The AELAB AE-SP4000 Series is built on an integrated aviation-grade aluminum alloy baseplate with a precision-machined mirror holder to ensure long-term optical stability. The AE-SP4000 incorporates a high-resolution C-T structure monochromator and a 1200 line/mm grating optical system for stable wavelength dispersion and reproducible UV-Visible analysis. Independently designed lamp replacement windows with flange-style positioning support controlled maintenance of the Deuterium lamp and Tungsten lamp.
🔬 Working Principle / Testing Method
The AELAB AE-SP4000 UV-Visible spectrophotometer quantifies sample absorbance and transmittance by selecting a defined wavelength within 190–1100 nm and measuring optical attenuation through the sample. Instrument electronics process photodetector signals to calculate Abs, %T, concentration factors, and spectral outputs. In scanning modes, the AE-SP4000 measures optical responses at defined intervals to generate spectra, identify peaks and valleys, and store traceable analytical results.
