Multiple internal reflectance accessory

WebReflection consists of two components: specular and diffuse. Specular reflectance is the mirror-like reflection off a sample surface. Diffuse reflectance occurs when the surface reflects light in many different directions, giving the surface a matte finish. Traditionally, the accessory used to measure diffuse reflectance is the integrating sphere. WebA typical number of reflections provided by various ATR accessories lies between 1 to 15, which translates to an effective pathlength of 1 to 25 micrometers – depending on the …
