Instrument Introduction:
The new generation double beam U3900/3900H UV-Vis spectrophotometer features the world's first variable speed testing in the ultraviolet range, reducing noise levels to one-third.
Technical Parameters:
Measuring wavelength range: 190 to 900 nm
Spectral bandpass: 0.1, 0.5, 1, 2, 4, 5 nm (6 kinds)
Wavelength accuracy: ±0.1 nm (656.1 nm)
Photometric range: Abs: -3.8 to 3.8 (U-3900), -5.5 to 5.5 (U-3900H)
%T: 0 to 300%T (U-3900/U-3900H)
Photometric accuracy: ±0.002 Abs (0 to 0.5 Abs)
±0.004 Abs (0.5 to 1.0 Abs)
±0.006 Abs (1.0 to 2.0 Abs)
Main Features:
Wavelength range: 190-900 nm with photomultiplier tube detector providing high detection sensitivity;
Options for single monochromator and double monochromator; the double monochromator provides a higher photometric measurement range and lower stray light levels, fully meeting the measurement requirements for high transmittance and high absorbance samples;
Upgraded 190-1100 nm photomultiplier tube detector selection, differing from the silicon photodiode 190-1100 nm, with completely different technical specifications for your high-demand data acquisition;
If you need to perform non-destructive measurements of optical components, please consider our upgraded sample chamber accessories.
