The OL 100U Irradiance Standard is a high-intensity standard consisting of a 1000- watt, DXW, tungsten-halogen lamp mounted in a slip-cast, fused silica reflector. The source has an effective radiating area of 3 x 5 cm. At a distance of 40 cm, the total irradiance is on the order of one solar constant (approximately 136 mW/cm2). Uniformity tests performed on a number of these units show that the irradiance in the specified direction over an area of 4 cm2 is uniform to ±0.25%.
