UV-Visible/NIR Spectrophotometer UH7500 Hitachi Japan

UV-Visible/NIR Spectrophotometer UH7500

Opening the way to the future, the UH5700, the spectroscopy specialist, handles the ultraviolet, visible, and near-infrared regions and strongly supports you.

Use of a continuously variable slit

The UH5700 employs a continuously variable slit in the near-infrared region, in which the slit automatically widens when measuring low quantities of light and narrows when measuring large quantities of light, and thereby achieves low-noise measurements across a broad range of measurement wavelengths from 190 to 3,300 nm.

Low stray light

The UH5700 achieves best-in-class levels of low stray light and high photometric range through use of a Czerny-Turner mounted single-monochromator bright spectrometer and a newly developed grating using photolithography technology. *¹

Measurement throughput improvements

By employing a gear-drive system for the wavelength drive, high scanning speeds compared to conventional instruments are achieved of approximately 0.3 to 5,000 nm/min in the ultraviolet-visible region. *² When measuring at a 1 nm interval, a measurement made at 1,000 nm/min in the 190 to 3,300 range can be completed in approximately 4 minutes.

Control of detector switching level difference

Generally, UV-visible/near-infrared spectrophotometers use different detectors in the UV-visible region and the near-infrared region. Because different detectors are used, a difference in photometric values may arise in switching between detectors. Through know-how developed from the fundamentals, signal processing technology, and other techniques, the UH5700 holds the level difference when switching detectors to a minimum.

Common utilization of accessories

The sample compartment shares a common design with the U-2900/U-3900 spectrophotometers, so you can use the accessories you already have.*³ We offer an extensive line-up of accessory types tailored to measurement objectives.
