    When Edmund Scientific introduced the telescope in 1976 they called it "The Edmund Wide-Field Telescope" with a Part Number "2001" [5] Edmund had a public contest which ran until November 15, 1976, to come up with a name. [6] The winning name was "Astroscan 2001". The "2001" part of the name was dropped over time.

    The Webb telescope uses 132 small actuation motors to position and adjust the optics. [39] The actuators can position the mirror with 10 nanometer accuracy. [40] Webb's optical design is a three-mirror anastigmat, [41] which makes use of curved secondary and tertiary mirrors to deliver images that are free from optical aberrations over a wide ...

  7. Photon counting - Wikipedia

    en.wikipedia.org/wiki/Photon_counting

    Photon counting eliminates gain noise, where the proportionality constant between analog signal out and number of photons varies randomly. Thus, the excess noise factor of a photon-counting detector is unity, and the achievable signal-to-noise ratio for a fixed number of photons is generally higher than the same detector without photon counting.
