Double Beam UV Visible Spectrophotometer NDUVS-203 is a compact and ergonomically designed analytical instrument for optical measurements such as transmittance or reflectance of transparent chemical solutions or opaque solids. It is equipped with tungsten and deuterium lamp as a source of light and a silicon photodiode as the detector. It runs in UV visible range of electromagnetic light spectrum with double beamed, blazed holographic grating optical system for optimized selection of wavelength across the working range for precise analysis.
