UV-Vis Fixed Angle Specular Reflectance accessories (slide mounted)
For Cary 50, 60, 100, 300, 400, 500, 500i, 4000, 5000, and 6000i instruments
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.
