Astrophotonics is the application of photonic technologies to channel. manipulate. and disperse light from one or more telescopes to achieve scientific objectives in astronomy in an efficient and cost-effective way. Utilizing photonic advantage for astronomical spectroscopy is a promising approach to miniaturizing the next generation of spectrometers for large telescopes. https://www.roneverhart.com/Plastic-Jigger-with-Measuring-Lines-Box-of-12/
