An Optical Method to Measure Time Response in Scanning Spectrophotometers

摘要

An optical method to measure time response in scanning spectrophotometers is described. The method is wavelength independent and can be used to check both the raise time and the fall time. The method was applied to a scanning spectrophotometer and the results were compared to those obtained for the same instrument using a kinetic method. The validity of the new method was demonstrated by the fact that the agreement between the results obtained using the two methods was complete.
