UV-Visible/NIR Spectrophotometer UH4150

Model U-4100, the expert in solid-phase spectrophotometry, has advanced even more.

Now, Model UH4150 has emerged inheriting the reliability of the U-4100 Spectrophotometer, which boasts the total number of shipments more than 1,500 units.

Small signal level differences at detector switching afford highly accurate measurements even when the wavelength of detector is being switched.

Multiple detectors are installed in the integrating sphere to perform measurement over a wide range of wavelengths, from ultraviolet to visible to near infrared regions. The changes in photometric values at detector switching (from signal level differences) are minimized due to a design utilizing Hitachi’s expertise in integrating sphere construction, signal processing technologies, etc.

Low stray light and low polarization characteristics are attained with Hitachi’s high-performance prism-grating double monochromator system.

The UH4150 adopts a prism-grating (P-G) double monochromator optical system, continuing the established reputation of the U-4100 optical system. Large changes in light intensity of the S and P polarization are less likely for the prism-grating (P-G) system than for the generally used grating-grating (G-G) system. The UH4150 offers low noise measurements, even for low transmittance and reflectance samples.

Collimated light beam allows accurate measurement of reflected light and scattered light.

The incident angle is important for the measurement of specular reflectance of solid samples. For focused light beam, the incident angle varies depending on the lens’s focal length, etc. Consequently, the values of simulation of design of optical thin films, such as dielectric multilayer film and prism, would differ from actual measured values. In the case of a collimated light beam, however, the incident angle is always the same with respect to the sample, leading to a highly accurate measurement of specular reflectance. Moreover, the collimated light beam is useful for the evaluation of diffusivity (haze) and the measurement of transmittance of lenses.

A wide variety of detectors affords the selection of detectors suitable for measurement objectives.

Eight types of integrating spheres of different materials, sizes, and shapes are available.

Lineup of Detectors

New ergonomic design has been adopted.

The door of sample compartment is modified to improve the operation. An ergonomic design is adopted by taking into account the operation of replacing samples and accessories.

Compatible with many of the U-4100 accessories.

Common accessories are available for both models. Accessories used with Model U-4100 can also be used with Model UH4150*4. Since the accessories are removable, they help to accommodate a wider range of measurement types.

Higher throughput than Model U-4100.

While maintaining the high-performing optical system of the model U-4100, the UH4150 provides higher throughput measurements. In the previous model, a scan speed of 600 mm/min was necessary for a measurement using a data interval of 1 nm. With Model UH4150, you can measure at 1 nm intervals while using a scan speed of 1,200 nm/min, reducing the measurement time significantly.*5 The UH4150 measures from 240 to 2,600 nm in approximately two minutes. It is effective for samples requiring measurement in UV-VIS-NIR wavelength range, such as Solar Reflective Materials.

Spectrophotometer U-3900/3900H

Covers a wide variety of analysis needs from liquid samples to solid samples. Line-up of two types that can be selected in accordance with the measuring object and application. For use in a wide range of fields that focus on water quality, the environment, biotechnology, pharmaceuticals, materials, etc.

This product is a PC controlled system.

Possible to perform measurements in a wide absorbance range with low stray light and low noise

The larger the amount of transmitted light, the lower the noise of the obtained absorption spectrum so that a wider absorbance range can be measured.
Measurements of high concentration samples can be performed over a wider concentration range.

Stable spectrometer with double beam optical system

The light source uses a WI lamp (visible range) and a D2 lamp (ultraviolet range) that switches wavelength depending on the measurement. The double beam system divides the monochromatic light so that the diffraction grates into the control and the sample with a rotational mirror, guiding the light to the sample chamber.

Single Monochrome Type U-3900 uses a spherical surface mirror in front of the entrance slit, while the Double Monochrome Type U-3900H uses diffraction grating.

UV Solutions for U-3900 (PC connected) allows for easy device control and supports various quantitative-analysis functions

Special operation software that offers substantial functions such as measurement data comparison and a preview function that allows for a more powerful analysis.

Substantial accessories for both liquid and solid measurements.

There is an abundant lineup of accessories to accommodate multiple sample and micro sample applications, etc.

Loaded with aberration-corrected concave grating

The U-3900/3900H provides aberration-corrected concave gratings with a Seya-Namioka Mount for the spectrometer. Both condensing and dispersing functions allow for a bright optical system, but with fewer mirrors so that light loss and aberrations are reduced.

Two types of optical systems: Single Monochrome (U-3900) and Double Monochrome (U-3900H)

A lineup of two models with different spectrum systems: Single Monochrome (U-3900) and Double Monochrome (U-3900H).

The Single Monochrome is suitable for a low-concentration sample since sample light energy is stronger compared tothe Double Monochrome. The Double Monochrome is suitable for a high-concentration sample since it can measure high absorbance with little stray light.

Double Beam Spectrophotometer U-2900/2910

Double Beam Spectrophotometer U 29002910

Spectrophotometer mounting a large-size color LCD, which is simpler to use and higher in dependability.
High resolution satisfying European Pharmacopoeia (spectral bandpass: 1.5 nm).
Trace-amount measurement in biotechnological field, etc. can be carried out using optional 50, 25 and 5 micro cells.
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 concavediffraction grating monochromator.
Because a concave diffraction grating has both beam condensing and dispersing functions, an optical system canbe 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 diffractiongrating 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 U-2900/2910 have also been made with this machine.

Spectral bandpass 1.5 nm satisfying European Pharmacopoeia
European Pharmacopoeia requires a ratio of 1.5 or larger when measuring 0.02% (V/V) solutions of toluene in hexane. In the spectrum at right, a satisfactory value of 1.6 can be confirmed.
(Sample: 0.02% solution of toluene in n-hexane)

Personal computer-based instrument control and data processing
U-2900 can be controlled by a PC equipped with optional UV Solutions Program. UV Solutions Program provides not only basic functions such as photometry quantitative analysis and wavelength scan but also the capability of data handling as described below.
