Non-uniformity of irradiance in the test plane, and irradiance time variation are class A.
Within ±2% (Class A Valid irradiation area: W1,800 x D1,500mm)
※ Reference cell and monitor cell are used to measure the value for every 100mm. Unevenness of irradiance across the cell
Between 0.75 and 1.25 (Class A)
Between 900 and 1000W/m22
Up to ±1% (Class A)
Effective irradiation area is measured in increments of 100mm using a reference cell and monitor cell (100mm□), instead of at 17 points as specified in JIS C 8912·8933.
