Integrating sphere detector, collimated beam, 2 in., 800-1650 nm

The 819C-IG-2-CAL is a NIST traceable calibrated integrating sphere detector using a 2 inch integrating sphere with a high performance InGaAs photodetector. The input port size is 0.5 in. diameter and the wavelength range is 800 – 1650 nm. 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 Note that the system calibration is no longer valid if any component is changed from the original calibrated configuration.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 only with no attenuator on the photodiode. If you have a legacy optical power meter that requires an 8-pin DIN calibration module, order 819C-IG-2-CAL/CM.
