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.
