Integrating Sphere Detector, Collimated Beam, 2.0 in., 400-1100 nm

The 819C-SL-2-CAL2V2 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 2 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 Note that the system calibration is no longer valid if any component is changed from the original calibrated configuration.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. It is replacing 819C-SL-2-CAL2.
