I am aware that i can do that by simply multiplying it by the norm, but some reflectance are above 100 hence, the norm equation would not be applicable.
So, I measured the absolute reflection of a solar wafer using a spectroscopy, and I was planning to do the following calculations:
actual reflectance = absolute reflectance x (1 - SQRT(1 - absolute reflectance)), but if the absolute reflectance was 250, then the square root would be negative and that does not add up.
Down below is the python code for the scheme above.
import math
def calculate_actual_reflectance(absolute_reflectance):
fraction = absolute_reflectance / 100.0
if fraction > 1:
actual_reflectance = 100
else:
actual_reflectance = absolute_reflectance * (1 - math.sqrt(1 - fraction))
return actual_reflectance
