Integrating Spheres

Advantages of LSI Integrating Spheres

• Auxiliary lamp and baffle included as standard for increased accuracy
• Sphere spectral characteristics are measured and corrections applied to give idealized paint reflectance response and photodetector response.
• For LED series spheres, range of LED sockets is included
• Kelvin 4-terminal socket included for standard lamps
• Computer-controlled lamp warm-up and stabilization detection is provided
• Set of three luminous flux standard lamps included
• With optional AC console, variable transformer power supply included for AC operation of test lamps
• Optional AC console provides switchover between test and auxiliary lamps under relay control

LSI’s computer-driven option enables additional benefits:

• Allows collection of primary and secondary HID ballast data with automatic meter switchover.  Similarly for LED power supply input and output data.
• Entire calibration and test procedure is computer prompted; data collection and computation is software operated for lumen and spectral quantities
• Fully integrated database capabilities included with computerized option for all lumen, spectral and electrical data
• Data collection over time provided at operator-specified intervals
