Cosine Response

Directional, or cosine, response is defined as the

measurement error at a specific angle of radiation

incidence. Error for Apogee SQ-100X series quantum

sensors is approximately ± 2 % and ± 5 % at solar

zenith angles of 45° and 75°, respectively.

Mean cosine response of five SQ-

100X series quantum sensors.

Cosine response measurements

were made by direct side-by-side

comparison to the mean of seven

reference SQ-500 quantum

sensors.
