Overview
Double Beam UV Visible Spectrophotometer NUVS-202 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 deuterium and tungsten lamp as a source of light and a silicon photodiode as the detector. It runs in a UV visible range of electromagnetic light spectrum with split beamed, blazed holographic grating optical system for optimized selection of wavelength across the working range for precise analysis.
