This report describes a way to perform diffuse reflectance measurements over the 1.0 to 3.0 micrometers spectral interval by using a Cary 17 l Spectrophotometer equipped with inexpensive standard accessory cell-space integrating spheres. The method involves coating the cell-space spheres with a powder of pure grade quenched sulfur with carbon disulfide used as a solvent and making a minor alteration in an electronic amplifier. A spectrum of ground gypsum crystal in the 2.6 to 3.0 micrometers spectral region and a spectrum of a layer of Hectorite clay in the 1.0 to 3.0 micrometers spectral region are presented to illustrate the applicability of the above technique for making diffuse reflectance measurements in the near infrared.
