Labsphere TruLume LED Uniform Sources for Image Sensor Testing
Integrating sphere light sources provide uniform radiance and irradiance
An internally illuminated integrating sphere (otherwise known as a "uniform light source") provides spatially uniform luminance and illuminance which is perfect for flat-field correcting and calibrating image sensors and camera systems, calibrating photometers and spectroradiometers and for testing detector arrays and remote sensing instruments. Integrating sphere-based sources exhibit a luminance uniformity at the 98-99% level over the full exit port area, which is significantly higher than can be achieved using alternative techniques. Labsphere TruLume uniform light source systems are ideally suited for flat-fielding and pixel gain normalisation of cameras and array detectors (CCD, CMOS).
