Description

Reflection and transmission are the basic optical properties of an item, and also the basic content of spectral measurement. For different types of samples, in order to obtain the best spectral measurement data, the two basic modes of reflection and transmission will evolve into more forms. There are mainly two kinds of reflections on the surface of the object: mirror reflection and diffuse reflection. The reflection of light on a perfectly flat surface is mirror. The reflection of light on a rough surface is diffuse. The reflection of light on the surface of most objects is somewhere in between. Reflectance measurement can be used to measure the reflectivity of components, measure the reflected color of objects and the composition information in chemical samples.

When we measure reflection on an object, it is very important to determine which type of reflection is mainly on the surface of the object.Most of the sample surfaces that look very dazzling or very shiny are mirror reflections. Because the angle of reflected light changes by 180 degrees relative to the incident light, an optical fiber can be used for sampling and measurement.
