Ideal for a wide range applications, the optical spectrum analyzer enables fast, high accuracy measurements of MWIR light spectra.

This material is intended for wavelength calibration of near‐infrared spectra and is especially critical for high‐resolution work. References We thank the NOAO director, Dr. Sidney Wolff, for ...

With winds blowing at 20,500 mph, "the planet has complex weather patterns just like Earth and other planets of our own system," scientists said.

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

But [Marb] has an answer for that; after gathering data at each wavelength, he applies a cubic spline interpolation to derive the spectrum. It’s demonstrated in the video below using chlorophyll ...

The team also compared the observed broadband multi-wavelength spectra with theoretical emission models. "The flare in 2018 exhibited particularly strong brightening in gamma rays. It is possible ...
