Abstract

A novel spectrophotometer based on the deflection of a secondary element for measuring clear and highly turbid materials within the millisecond time range is 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. The main philosophy is to relocate as many functions as possible from the hardware to the software part of the spectrophotometer. Several novel procedures based on old concepts are proposed. An appropriate computer program providing data acquisition, control functions as well as numerous analytical capabilities is developed on the basis of the compiler language power basic and indispensibly "fast" routines are written in assembler language.
