An international collaboration of researchers developed two new complementary approaches for versatile but precise light intensity measurements in fluorescence imaging systems. Accurate measurements ...

Measuring the average intensity of the visible radiation emitted from an LED is a critical issue, not just for developers of electro-optical instrumentation and photonics measuring devices, but also ...
