The UH5200 offers comfortable operation with a large color LCD for excellent visibility and a keypad for confident input. Choose standalone control or PC control to match your workflow. Sample-compartment compatibility with the previous U-2900/2910 models is also maintained.

The UH5200 series lineup consists of the UH5200, a standalone instrument, and the UH5210, a PC-controlled instrument.

The UH5200 features a 10.4-inch backlit color LCD display with 800×600-pixel resolution—higher than the previous-generation U-2900 system—to allow detailed visualization of calibration curves and measured spectra. The layout of the display screen is unchanged from that of previous-generation instruments, offering users a familiar operating experience with enhanced readability thanks to a new graphic design. A dedicated keyboard allows accurate, worry-free input.

The UH5210 is a fully PC-controlled instrument. Its control software is UV Solutions Plus, a new platform that is an update to the UV Solutions control software of the previous-generation U-2900 system with expanded functionality, including display of data lists and data-processing results in tabular form, report layouts, and performance validation. The UH5200 also offers the option of adding the UV Solutions Plus software platform to allow PC control.

Stable optics due to double beam

In double beam design, the energy of the light source is divided into two with a half mirror so that one passes through the reference side, and the other through the sample side, which is unavailable with the single beam design. Since the reference-side energy is also incident on a detector, photometry is carried out on the basis of this signal. Therefore, an energy change in the light source can be compensated to ensure stable measurement for a long time.

Incorporation of stigmatic concave diffraction grating

The optics of this instrument adopts the Seya-Namioka monochromator widespread as a representative concave diffraction grating monochromator. Because a concave diffraction grating has both beam condensing and dispersing functions, an optical system can be configured with fewer mirrors.
In a spectrophotometer, use of fewer mirrors signifies a shorter optical path, thus giving rise to an aberration-free bright optics.

For elimination of the aberrations which were essentially unavoidable in the past, a stigmatic concave diffraction grating has been developed by applying Hitachi’s original technology. As a result, a higher resolution has been realized.

A higher resolution has been achieved by eliminating coma from the Seya- Namioka monochromator which is the most popular concave diffraction grating monochromator. Its grooving is supported by the only ruling engine in Japan. The diffraction gratings of Model UH5200/5210 have also been made with this machine.
