    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 ...
