We measure illuminance (lux), defined as the ratio of luminous flux (lumens) incident on a surface to the unit area (m²).
The spectral response curve of the light measurement probe approximates the human eye's response curve known as the standard photopic curve V(λ). The difference between the "WPLP-PHOT-01" in spectral response and the standard photopic curve V(λ) is calculated as the error f'1. Calibration of the probe is performed by comparing it with a photometer that has been calibrated by a primary metrology standard institution. The calibration procedure complies with CIE Document No. 69 (1987) "Method of Characterizing Illuminance Meters and Luminance Meters." Measurements are conducted by illuminating the probe with standard light A. The outdoor installation type is the MC8P-PHOT3S series.
