The JWST is the telescope that will follow Hubble Space Telescope. It is something I thought to write about because it is not that easy at the moment to get information about the optics details in particular of the telescope.
At the just ended 2009 SPIE Annual meeting, I presented my work to create an estimated model of the very complex (from an optical design perspective) NIRSpec instrument being built now, in Europe, for the JWST. This instrument consists of the JWST (an obscured, field-biased Three Mirror Anastigmat (TMA) followed by a Relay, Collimator, grating, and Camera, each of which is itself an unobscured TMA. I will write more on this paper at another time.
