Straylight measurements of immersed gratings for high-resolution spectroscopy in the near infrared

Overview of diffraction gratings technologies for spaceflight satellites and ground-based telescopes

“…of SPIE Vol. 10563 105630P-7 The efficiency measurements ranging from ~75% to >90% for the 750-775nm spectral range, were in good agreement with the calculated efficiencies [8].…”
