UV-VIS-NIR Spectroscopy with IRS

About the UV-VIS-NIR Spectroscopy Facility

The V-770 Double Beam UV-Visible/NIR Spectrophotometer (JASCO) is a high-performance analytical instrument designed for precise and stable measurements across a wide spectral range from UV to near-infrared (≈190-2700 nm). It features a single-monochromator, double-beam optical system that ensures excellent baseline stability, low stray light, and high signal-to-noise ratio, supported by a PMT detector for UV-Vis and a Peltier-cooled PbS detector for NIR. The instrument offers flexible bandwidth selection, fast scanning speeds, and seamless control through Spectra Manager™ software, making it suitable for both routine and advanced analyses. Applications include optical characterization of semiconductors and nanomaterials, band-gap estimation, thin-film and coating analysis, diffuse and specular reflectance studies, quantitative analysis of solutions, and material research in physics, chemistry, materials science, pharmaceuticals and environmental studies.
