Uniform Light Sources

An internally illuminated integrating sphere provides spatially uniform luminance and illuminance which is perfect for flat-field correcting and calibrating imaging systems, calibrating photometers and spectroradiometers and for testing detector arrays and remote sensing instruments. Integrating sphere-based sources, also known as uniform light sources, exhibit 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´s uniform light sources are coated with high reflective Spectraflect coating. A number of different optical accessories like optical attenuators, filter wheels, different types of detectors and the option of Spectralon coating allow an easy adaption of standard uniform light sources to almost any application. All light sources are controlled by a user friendly software interface.
