819D-IG-2-CAL In Stock

The 819D-IG-2-CAL by Newport is an Integrating Sphere Detector engineered to excel in the measurement of collimated light sources. This specialized detector employs a 2-inch integrating sphere in conjunction with a high-performance InGaAs photodetector characterized by a 0.5-inch diameter input port and an operational wavelength range spanning from 910 nm to 1650 nm. It is important to note that the elevated operating temperature of the 819D-IG-2-CAL can exert an influence on measurement accuracy. To mitigate this, the integral sphere incorporates a temperature control feature capable of maintaining precise thermal conditions even under demanding power levels.

The 819D-IG-2-CAL features an SMA fiber optic connector that enables the extraction of a small portion of incident light for wavelength measurement and further analysis without compromising the overarching system calibration. A primary advantage of this detector is its aptitude for diffusing the input beam. By doing so, the detector readings remain impervious to potential saturation of the photodetector's active region, issues arising from overfilling, or inaccuracies stemming from detector positioning. This capacity is augmented by the presence of a baffle, strategically positioned between the detector and input port to prevent the direct impact of the undiffused beam upon the detector. The design of the 819D-IG-2-CAL is tailored to accommodate diverging light sources, encompassing lensed lamps, lensed LEDs, and laser diodes. This detector has calibration traceability to NIST standards, affirming its adherence to rigorous calibration protocols and imbuing it with one of the most minimal calibration uncertainties available in the market.
