Opening the way to the future, the UH5700, the spectroscopy specialist, handles the ultraviolet, visible, and near-infrared regions and strongly supports you. Features Handling the ultraviolet, visible, and near-infraredregions (190 to 3,300 nm), the UH5700 achieves both high measurement precision and high throughput 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, 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.
