Cosine Response
Cosine Response Graph
Directional, or cosine, response is
defined as the measurement error at
a specific angle of radiation incidence.
Directional error for Apogee SU-200
series UV-A sensors is approximately ±
2 % and ± 5 % at solar zenith angles of
45° and 75°, respectively.
Mean cosine response of four
Apogee UV-A sensors. Cosine
response was calculated as the
relative difference of UV-A
sensors from the mean of
replicate reference UV-A
sensors deployed outdoors.
These data are the average of
the AM and PM response.
