UV sensor. Glossary Terms and Units These terms apply to solar radiation measured with the Delta-T range of energy sensors (types ES2, UV3p, GS1, GS2, TSL) and the PAR Quantum Sensor type QS2. Cosine Corrected Refers to a sensor that is designed to have a cosine response. - Page 24 Cosine Response A sensor with a true cosine response gives an output that is proportional to the cosine of the angle of incidence of the ray of light. The angle of incidence is the angle between a perpendicular to the sensor surface and the ray of light.
