Smartphones are a potentially powerful platform for scientific instruments. Here, we demonstrate speckle spectroscopy with smartphone-level hardware. This technique promises greater performance ...

Solar radiation is the most important external energy of the earth's climate system. Monitoring the change of solar radiation is of great significance to solar physics and atmospheric physics. At the ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...

Rendering of prism and spectrum Optical spectroscopy splits light and measures the intensity of different wavelengths. It is a powerful technique across a wide range of applications. UC Davis ...

Variability must be avoided for OEM instrument developers who must guarantee an answer based on the quality of a Raman spectrum. These answers are important to their customers and those influenced by ...
