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. ...

NIFS is designed to be a fast-tracked, low-cost, near-infrared, integral-field spectrograph for use on Gemini North with the facility adaptive optics system, ALTAIR . ... By adopting a largely fixed-format design: A 3.0" 3.0" "stair-case" integral field unit (IFU) will feed a near-infrared spectrograph with five fixed-angle gratings mounted on a single grating wheel. ... The 29 field mirrors direct the beams into the spectrograph so that their pupils all coincide on the grating at bottom-left. ...

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). ...

We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

... 400mm f/2.8 Nikor lens: images the sky on the entrance slit. ... The optical system maintains image quality along the slit length so that each row of the image is a spectrum of that spatially selected region of the sky. 180mm f/2.8 Nikor lens: collimates the light from the slit. ... The auxiliary optical platform on WISPI now accomodates a short focal lens and a guiding/imaging video system that may use sub-pixel corrections to provide feedback to the tracking drive motors. ...

... 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. ...
