Summary
| Description |
English: WFI computer models and hardware photographs. (a) Hardware model of the fully assembled WFI. (b) Exploded view of WFI with key components labelled. EWA: Element Wheel Assembly. COBA: Cold Optical Baffle Assembly. ACM: Alignment Compensation Mechanism. FPA: Focal Plane Assembly. sRCS: simplified Relative Calibration System. (c) Completed WFI, held aloft by a crane. The fine hardware features are obscured by multilayered insulation (MLI) at this final stage of assembly. (d) View of the EWA attached to the optical bench prior to installation of the aperture cover to highlight all eleven of the optical elements on the wheel. (e) Close up on one filter element, F106. The filter mask fiducial pattern and the gold-coated Lamp on Lamp off (LOLO) element hiding on the other side of the filter mask can be more easily seen in this perspective shot prior to installation onto the wheel. A reflection of the American flag painted on the wall of the cleanroom is reflected off the front surface of F106 in this picture. |
