Abstract. Design peculiarities, technical features, and basic performance characteristics of laboratory spectrophotometer for measuring UV spectral transmission of various objects are considered. Results of device testing with solid state optical materials, aqueous solutions of phenols and oil products are presented. Perspectives of the spectrophotometer employment in control over chemical technological processes (e.g., bleaching in pulp industry) are also discussed.
Keywords: ultraviolet spectroscopy, optical materials, photometry of phenols and oil products, optics of cellulose, Kubelka—Munk theory.
