Corresponding Author: Dr. Gabriele Corciolani, Via Derna 4, 58100 Grosseto (Italy) E-mail: [email protected]; Tel/Fax: +39056425384 Abstract Objectives: The aim of this study was to evaluate the repeatability of readings with a clinical spectrophotometer in comparison with a laboratory one. Materials and Methods: A stand alone clinical spectrophotometer (Easyshade, Vita) and a labor...
We built a transient absorption spectrophotometer that can determine transient absorption spectral changes that occur at times as fast as approximately 200 ns and as slow as a minute. The transient absorption can be induced by a temperature-jump (T-jump) or by optical pumping from the deep ultraviolet (UV) to the infrared (IR) by use of single ns Nd:YAG laser pulses. Our use of a fiber-optic sp...
