WebInfrared Spectroscopy— Proceed as directed under Multiple Internal Reflectance in the section Test Methods. The corrected spectrum of the specimen exhibits major absorption … 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.

Schematic arrangement of conventionai diffuse-reflectance accessory for measuring multiple ... WebInternal reflection can only occur when the angle of the refracted beam θ t is larger than the angle of incidence θ i.This means, according to Snell's law (Equation 2), that the refractive index of medium 2 must be smaller than that of medium 1 (n 2 < n 1).This is contrary to the situation in Figure 1 where n 2 >n 1 was assumed. The region of total …

The most popular and easy-to-use technique … WebReflectance measurements can be divided into two basic categories – internal or external reflectance. The technique of Attenuated Total Reflection (ATR) is employed for internal reflectance measurements as the beam of infrared radiation passes through an ATR element (crystal) in contact with the sample.
