Abstract
A simple reflectometer for measurement of specular reflectance at normal incidence, has been designed and developed in the laboratory. It is being used for characterisation of plane specuarly reflecting surfaces. In the present article the experimental setup of the reflectometer and results of measurements on a few samples are presented along with the related uncertainties as estimated by following standard procedure. The remarkable feature of the reflectometer is that it doesnot require a standard sample for comparision. Moreover, it can be employed to calibrate other reflectometers as well as standard samples.
