WFPC2 has corrective figures on the relay secondary mirrors where the primary mirror is imaged; this optical correction recovers near-diffraction limited images over the entire CCD fields-of-view. Proper correction requires tight optical alignment tolerances, which are facilitated on-orbit by actuated optics. ... Alignment stability error . ... The optical design of WFPC2 creates an image of the OTA primary mirror near the surface of the relay Cassegrain secondary mirror in each of its channels. ...

The optical scheme of the instrument is sketched in Figure 1 , it is designed to match the F/20 focal ratio of the TIRGO telescope. We have, following the optical path, the window of the dewar, the order sorting filter (not in figure), a field lens, in Calcium Floride, and the slit, in the focal plane of the telescope. ... The resolving power is (for first order of grating) of about 600 in the center of J band and 950 in the center of the K band, using a slit of two pixel (3.46 arcsec). ...

Between the end of 2010 and the summer 2011, the E-ELT project extended the detailed design phase in order to consider the recommendations of the E-ELT Design Review, and in June 2011 the ESO Council endorsed a revised baseline design for the E-ELT. ...

... The collecting area is increased by nesting concentric mirror pairs, all having the same focal length. ... Figure shows the largest optical element being ground at HDOS. ... X-ray testing demonstrated that the CXO mirrors are indeed the largest high-resolution X-ray optics ever made; the nominal effective area (based on the ground calibrations) is shown as a function of energy in the left panel of Figure , along with those of their Einstein and ROSAT predecessors. ...
