Reflectance and Transmission
- Light from external sources/daylight can change the reading of the photodiode.
- If light is not aligned parallel it can change the readings of the photodiode.
- Improper adjustment of the 0° can lead to wrong value for the Brewster angle
- If, for each angle of incidence maximum reading is not ensured, graphs will not be correct.
- Identification of the minimum reflected intensity.
