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

Physicists use a 350-year-old theorem that explains the workings of pendulums and planets to reveal new properties of light waves. Since the 17th century, when Isaac Newton and Christiaan Huygens ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...

Unlike existing photodetectors that construct and integrate wavelength- and/or polarization-sensitive elements in space or time to improve the detection ability (range and sensitivity), this ...
