Document: SOW for Design and Analysis for HOWFSRevision: ADate: 14 June, 20131. GENERAL WORK DESCRIPTION1.1 DESIGN OPTIMIZATION STUDYThis Statement of Work (SOW) defines the tasks and deliverables that shall be performed and providedby the Contractor. This effort shall be hereinafter referred to as the Work.The Work shall consist of the Contractor reviewing and analyzing the provided Wavefront Correction(WFC) High-Order Wavefront Sensor (HOWFS) conceptual design (see Appendix A),makerecommendations for optimizing the design with respect to: manufacturing feasibility; cost-effectiveness;and likelihood of achieving performance requirements, and develop a final toleranced design based uponthose recommendations and feedback/review by AURA.1.2 MEETINGSContractor shall organize and conduct, at a minimum, the following meetings:1.2.1 Meeting ScheduleTimeT0T0 + 1 weekT0 + 2 weeksT0 + 4 weeksT0 + 6 weeksEvent*AwardKick Off1 st Progress Review Meeting2 nd Progress Review MeetingFinal Design Review MeetingT0 + 8 weeks Final Report MeetingT0 + 9 weeks AURA Report Review periodT0 + 10 weeks Revised Final report due*See Section 1.2.2 for specific meeting content and objectives1.2.2 Meeting ContentKick-off meeting - to discuss the objectives of the Work and to ensure that the requirements are clear andsufficient for the Work to proceed. Contractor shall propose a schedule with a goal of submitting the FinalReport within 8 (eight) weeks from contract award, followed by a one week AURA review period and aone week Contractor response period. The proposed schedule shall include major milestones of theoptical design and tolerance analysis.1 st Progress review meeting - to review the feasibility, status and progress of the optical design.Contractor shall provide preliminary results, identify any remaining issues, a summary of theoutcomes, a preliminary Zemax model for review. and any action items resulting from this meeting.2 nd Progress review meeting - to review the final optical design and review the steps of thetolerancing effort. Contractor shall provide preliminary results, identify any remaining issues, asummary of the outcomes, the final Zemax model for review, and any action items resulting from thismeeting.Page 4 of 10
Document: SOW for Design and Analysis for HOWFSRevision: ADate: 14 June, 2013Final design review meeting - to review the tolerance and sensitivity analysis of the final design.Contractor shall provide results, identify any remaining issues, and shall summarize the outcomes andany action items resulting from the meeting. The intent of the final design review meeting is toidentify any remaining issues or areas requiring further work before the final report can be submittedFinal report meeting - to review the final report. Contractor shall provide a preliminary final report toAURA for review and comment not later than 1 week before the final review meeting. Should AURAfind deficiencies in either the preliminary report or the meeting contents, AURA will return thepreliminary report with comments not later than 1 week following final meeting so as to allow theContractor to take any corrective actions.1.3 COMPLETIONThe Contractor shall complete the Work within the 8 week schedule. Weeks 9 and 10 are reserved forAURA review/comment of the Final Report and the Contractor’s responses, respectively.2. DELIVERABLESThe Contractor shall deliver the following:2.1 REPORTSA preliminary and after revisions, a final report, in electronic format ( i.e. .PDF and/or MS Word) thatshall contain:- A description of the work performed.- Optical design description including a requirements compliance matrix.- Notable analysis features.- Monte Carlo tolerance analysis description, including error distribution assumptions.- Monte Carlo tolerance results indicating the statistical distribution of top level performance and asensitivity analysis in tabular form. This shall include fabrication, mounting, and alignmenttolerances.- Table of compensator ranges.- Conclusion of results and identification of tolerances that significantly increase fabricationrisk,cost, and mounting/alignment complexity- List of contents included in the data package.2.2 CONTENTS OF THE DATA PACKAGE; DIRECTORY OR FILE:- The Zemax optical design file for the final design including a lookup table for the position ofthe triplet lenses as a function of zoom.- A lookup table of the position of the Cooke elements and other components as a function ofzoom.- Drawings directory: contains the optical element drawings in ISO 10110 PDF format.- WFC tolerance models: the Zemax models used to generate the tolerance RMS wavefronterror sensitivities and to run the Monte Carlo analysis. This contains the Zemax ToleranceData Editor table of values.- WFC element drawings: the Zemax models that contains the ISO 10110 element drawings.Page 5 of 10
