Paper Abstract

A novel spectrophotometer as based on the deflection of a secondary element for measuring clear and highly turbid materials within the millisecond time range has been developed. The number of optical components of the monochromator is reduced to the absolute minimum. This results in excellent light-throughput and a low stray-light level. The spectrophotometer has been designed allowing spectral measurements of absorption, transmission, reflection and luminescence in a single beam mode as documented by various examples. Its design is highly flexible and the price/quality relation might be adopted to the envisaged purpose. An appropriate computer-program providing data acquisition, control functions as well as numerous analytical capabilities has been developed on the basis of the compiler language power basic; indispensably `fast routines' are written in assembler language.
