Universal Reflectance Accessory (URA)

7/23/2019 SID Presentation Spectrophotometer

17/24

Angle specular reflectance measuring module that loads directly into the

detector compartment of the High-performance Lamda spectrometers.

Can be used to collect absolute or relative reflectance measurements with

an angle of incidence in the range 8 65, and utilizing wave lengths in the

range 3100 190nm.

Samples are placed on the horizontal sample plate and can range in size

from 8mm to greater than 150mm.

90 means P component0 means S component

At the angle is 57(it is the Brewster angle), P components reflectance

will be very few so we can focus on S component for measuring thespecular reflectance.
