The Reflection Accessory is used as a special accessory for UVS-2700, UVS-2800 and UVD-3500 Spectrophotometers.
It is applied to the examination of the reflectance and reflective spectrum of reflecting components and materials, such as mirrors, crystals and so on.
Optical principle
“Specular reflection” means that the optical mirrors reflect instead of diffuse transmission according to Newton Law. That is to say, the incidence angle is equal to the reflection angle.
According to Fresnel Law, the light will have polarization while reflection. The 5º incidence angle minimizes the influence of polarized light. The measuring results can be approximately regarded as the reflectance of projectivity.
