SUV-1200 Series UV-Vis Double Beam

General and Optics

• Models: SUV-1201, SUV-1202 and SUV-1205 (deuterium and tungsten lamps); SUV-1201 Xe and SUV-1202 Xe (xenon lamp)
• Optical System: Double beam. One beam passes through the sample and the other serves as a reference, so readings stay steady even if the lamp fluctuates
• Wavelength Range: 190–1100 nm
• Spectral Bandwidth: 1 nm (SUV-1201); 2 nm (SUV-1202); selectable 0.5 / 1 / 2 / 4 / 5 nm (SUV-1205)

Accuracy and Measurement Performance

• Wavelength Accuracy: ±0.1 nm at the D2 peak (656.1 nm); ±0.3 nm across the whole range
• Wavelength Reproducibility: ±0.1 nm
• Scan Speed: Up to approx. 3000 nm/min
• Photometric Accuracy: ±0.2%T (0–100%T); ±0.002 Abs (0–0.5 Abs); ±0.004 Abs (0.5–1 Abs)
• Photometric Reproducibility: ±0.15%T (0–100%T); ±0.001 Abs (0–0.5 Abs); ±0.002 Abs (0.5–1 Abs)
• Transmittance Range: 0–200%T
• Absorbance Range: -0.3 to 3 Abs
• Stray Light: ≤0.02%T at 220 nm (NaI) and 340 nm (NaNO2); ≤1%T at 198 nm (KCl)
• Baseline Stability: ±0.0003 Abs/h at 500 nm
• Baseline Flatness: ±0.0006 Abs
• Noise (at 500 nm): ≤0.0001 A peak to peak; ≤0.00005 A RMS
