Directional, or cosine, response is defined
as the measurement error at a specific
angle of radiation incidence. Error for
Apogee SE series photometric sensors is
approximately ± 2 % and ± 5 % at solar
zenith angles of 45° and 75°, respectively.
Cosine response
measurements were
made by direct side-by-
side comparison to the
mean of four reference
SE-100 photometric
sensors.
