UV-Vis-NIR Fixed Angle Specular Reflectance Accessories (slide mounted)
An external specular reflectance accessory (SRA) allows specular reflectance measurements to be made at fixed angles of 30°, 45°, or 60° depending on the accessory. These accessories are useful for studies of film thickness on metallic substrates and measurements of epitaxial film thickness.
The baseline is set by placing a reference material on top of the accessory and collecting the baseline. The reference material is then replaced with the sample lying face-down on top of the accessory to complete the measurement. These accessories have been designed for Cary 60, 4000, 5000, 6000i and 7000 instruments.
