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 ...

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

A waveguide that converts light from the near-infrared part of the spectrum to the visible is allowing scientists to improve the sensitivity of an infrared spectrometer. Researchers at Stanford ...

Femtosecond direct laser writing as a 3D printing technology has been one of the key building blocks for miniaturization in modern times. It has transformed the field of complex microoptics since the ...

Researchers have developed a new smaller, lighter design for space-based imaging spectrometers with high spectral resolution. These high-dispersion imaging spectrometers could be used onboard ...
