Design of freeform diffraction gratings: performance, limitations and potential applications (2018)
Presentation / Conference Contribution
Calcines, A., Bourgenot, C., & Sharples, R. M. (2018, June). Design of freeform diffraction gratings: performance, limitations and potential applications. Presented at Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation III: SPIE Astronomical Telescopes + Instrumentation 2018, Austin, Texas

Spectroscopy is a key technique in astronomy and nowadays most major telescopes include at least one spectrograph in their instrument suite. The dispersive element is one of the most important components and it defines the pupil size, spectral resolu...
