The 819D-SL-2-CAL2 is a NIST traceable calibrated integrating sphere detector using a 2 inch integrating sphere with a high performance silicon photodetector. The input port size is 0.5 in. diameter and the wavelength range is 400 – 1100 nm, with maximum power up to 4 watts. It comes with an SMA fiber optic connector on the North pole as a standard feature allowing a small amount of light pickoff for wavelength measurement or any further analysis without affecting the overall system calibration. Note that the system calibration is no longer valid if any component is changed from the original calibrated configuration. For a very high power level, elevated temperature of the integrating sphere system can affect the measurement accuracy so the sphere must be temperature controlled. Calibration is done with and without attenuator.

819D-SL-2-CAL2是NIST可跟踪校准的积分球探测器，使用2英寸积分球和高性能硅光电探测器。输入端口大小为0.5英寸。直径400 - 1100 nm，最大功率达4瓦。它带有一个位于北极的SMA光纤连接器作为标准特性，允许少量的光传感器进行波长测量或进一步分析，而不会影响整个系统的校准。请注意，如果任何组件从原来的校准配置更改，则系统校准不再有效。在功率很高的情况下，积分球系统的温度升高会影响测量精度，因此必须对积分球进行温度控制。校正是在有衰减器和没有衰减器的情况下进行的。
