Cosine Response 

Directional, or cosine, response is defined as the 
measurement error at a specific angle of radiation 
incidence. Error for Apogee MQ-600 series ePAR 
Sensor is approximately ± 2 % and ± 5 % at solar 
zenith angles of 45° and 75°, respectively.  

 

Mean directional (cosine) 
response of seven Apogee series 
quantum sensors. Directional 
response measurements were 
made on the rooftop of the 
Apogee building in Logan, Utah. 
Directional response was 
calculated as the relative 
difference of quantum sensors 
from the mean of replicate 
reference quantum sensors (LI-
COR models LI-190 and LI-190R, 
Kipp & Zonen model PQS 1). Data 
were also collected in the 
laboratory using a reference lamp 
and positioning the sensor at 
varying angles.
