Nightly, all over the world, observatories open their domes to collect light from the far reaches of the universe. The telescopes within diligently condense these precious photons for careful analysis by instruments like spectrographs, which further break down that light into its component colors. Over the past 20 years, Wasatch Photonics has provided VPH gratings used in astronomical spectrographs for telescopes ranging from 1.3 to 11 meters in size, installed all over the world.
