RFA7 features a collimated beam that strikes the sample at a 7° angle of incidence. The size of the collimated beam at the sample is approximately 10 mm. The accessory may be used to measure the reflectivity of glass per ASTM Standard E1585-93 and other specular reflectance experiments. RFA7 is well suited for specular reflectance measurements of polymers, reflectivity studies of polished metals and transmission-reflectance work.
Reflectance spectroscopy is useful for the measurement of films on metallic substrates, the thickness of free-standing transmitting films and for the characterization of samples which do not transmit IR radiation and so cannot be measured by other techniques.
