·         Wavelength range 190-1100nm

·         Double beam optical system

·         Variable bandwidth from 0.1 to 5nm

·         USB communication between the spectrophotometer and a PC, and the flat top of the instrument allow to place a notebook computer on the instrument.

·         Instrument control and a wide variety of quantitative analyses using the UV Solutions for U-3900 software are available.

·         The optical system and the control system were redesigned to improve basic performance, such as the baseline stability.

·         Share most commonly used accessories with other Hitachi Spectrophotometer (U-2900)

·         A double-beam monochromator with the Seya-Namioka mount provides an ideal optical system. The U-3900 model employs a single monochromator having a spherical mirror in front of the entrance slit, whereas the U-3900H model employs a double monochromator having a grating for the prevention of stray light.

·         The weight and the maximum power consumption were reduced (10% and 25% from the current models, respectively).

·         The scan speed for measurement at UV wavelengths can be changed. Scanning over the broad wavelength range from long wavelengths to short wavelengths gives a clear spectrum without requiring repeated scans.

·         A full complement of optional accessories are available to support both liquid-sample and solid-sample analyses.
