WebJul 27, 2016 · Sending a telescope into space comes at a high price, for more than one reason. Launching the Hubble Space Telescope was costly because it was heavy, due in part to its massive, rigid primary mirror and mirror mount. Building the James Webb Space Telescope, let alone launching it, is costly not only due to its weight, but also the fact that … WebAug 30, 2024 · The proposed and experimentally demonstrate an achromatic imaging in the full-visible wavelength range with a single dual-pinhole-coded diffractive photon sieve (PS) and provides a novel and practical way for achieving a chromatic imaging within the full visible range with features of thin, light and planar.
