UV-Visible/NIR Spectrophotometer

JASCO UV-Visible/NIR spectrophotometers provides an excellent optical system with wide wavelength range for a diverse array of applications.

For scientists performing spectral characterization, thermodynamic studies, and quantitative measurements for advanced bio- and materials research, who need confidence in the accuracy and reproducibility of their measurements and rely on the results.

V-700 Series comprises five distinct models covering the entire spectrum from the far-UV (187 nm) to the near-IR (3200 nm). The compact optical design of the V-700 Series of UV-Visible spectrophotometers significantly reduces the requirement for bench space in the modern laboratory.

V-770 UV-Visible/NIR Spectrophotometer

V-770 UV-Visible/NIR Spectrophotometer up to 3200 nm

The V-770 UV-Visible/NIR spectrophotometer features a unique single monochromator design for maximum light throughput with excellent absorbance linearity.

A PMT detector is used for the UV to visible region and a Peltier-cooled PbS detector for the NIR region.

The V-770 measures the wavelength range of 190 to 2700nm (option 3200nm).

The single monochromator design offers a significantly higher energy throughput than a double-monochromated design resulting in a better S/N ratio over the entire spectral range, even with narrow spectral bandwidth.

V-770 can be equipped with Integrating spheres measure either the diffuse transmittance or reflectance of a liquid, solid or powder samples.

Typically UV-Visible or UV-Visible/NIR spectrophotometers are used to measure the transmittance of a homogeneous, transparent liquid or solid sample. However, when the light is diffusely scattered by samples such as suspended liquid, opaque solid or powders only a small portion of the light reaches the detector.

An integrating sphere captures most of the light from the sample offering a more representative measurement of the sample. All JASCO Integrating spheres include built in detectors for optimal sensitivity – PMT for UV-visible, InGaAs up to 1600nm and PbS up to 2500nm.
