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.

: 1.5 to 2,400 nm/min, U-2900 : 10 to 3,600 nm/min.
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.
