MR191 Specular Reflection Accessory UV-Vis Spectrophotometer Accessories
 

The specular reflection accessory can measure the reflectance spectrum of optical surfaces, crystals and coated samples.
If  the reflecting mirror on the reference beam is the “standard reflecting mirror”, the user can calculate the absolute reflectivity of the measured surface.
The reference reflecting mirror as a standard configuration in the accessory is not demarcated, so only relative reflectivity can be measured. The demarcated reflecting mirrors are offered as optional accessories.
