Abstract

The use of an optical multichannel analyzer in reflectance and transmittance spectrophotometry has been studied. An instrument was developed based on the Shaw-Blevin reflectometer and was capable of collecting optical reflectance and transmittance data at a rate of up to 1024 samples in 17 ins. The accuracy of the apparatus has been assessed by comparison with the measurements made on the same specimens using a commercial spectrophotometer fitted with a Strong reflectometer.
