The Hitachi UH5700 UV-Vis-NIR Spectrophotometer is a high-precision benchtop analytical instrument designed for advanced spectral analysis across the ultraviolet, visible, and near-infrared regions (190–3300 nm). Engineered with Hitachi’s advanced optical technology, the UH5700 provides exceptional measurement accuracy, low stray light, and a wide photometric range, making it ideal for demanding research, industrial analysis, and quality control applications.
The instrument utilizes a Czerny-Turner mounted single monochromator with an advanced grating system, delivering highly stable spectral performance across an extended wavelength range. A double-beam optical design ensures improved measurement stability and reproducibility, while the system’s continuously variable slit automatically adjusts to optimize signal detection. This dynamic slit mechanism widens when measuring low light intensity and narrows for stronger signals, enabling precise, low-noise measurements over a broad spectral range.
The UH5700 supports high-speed spectral scanning and accommodates a wide variety of sample types through its versatile accessory options. The spacious sample compartment allows measurements of both liquid and solid samples, including optical materials, coatings, and thin films. Accessories such as integrating spheres, reflectance measurement modules, and specialized sample holders further extend the instrument’s capabilities for advanced materials characterization.
Instrument control and data processing are managed through UV Solutions Plus software, which provides powerful analysis tools, enhanced data visualization, report generation, and performance verification functions. The software also supports tabular data display and flexible report formatting, allowing laboratories to efficiently analyze and document measurement results.
