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. http://www.pharmacopeia.cn/v29240/usp29nf24s0_c661s80.html
