The process combines three technologies to provide a cost and schedule effective solution for lightweight, thermally stable precision optics for EUV applications. First, near-net-shape cast SiC materials for monolithic lightweighted, SiC mirror substrates with minimal machining required. Second, a thin CVD SiC sputter deposition process applied to the mirror facesheet. This enables a low-scatter surface as well as high reflectance in the EUV band. Third, the application of Tinsley?s computer controlled optical surfacing (CCOS) grinding and polishing makes it possible to generate aspheres with extremely accurate surfaces. The manufacturing process proposed allows production of state-of-the-art SiC aspheric mirrors with numerous benefits compared to competing technologies and traditional processes: ?Excellent Surface Figure Accuracy (<0.01 waves RMS, over low and mid-spatial-frequency measurements); ?Ultra-low micro-roughness (<10 Angstroms RMS routine, <1 Angstrom RMS achievable); ?Improved yield; ?Very low areal densities (~10 kg/m2 at an aperture of 1 meter); ?Superior thermal stability (SiC bulk material properties); In Phase 2, SSGPO will demonstrate an optimized optical fabrication process by producing a SiC EUV flight-ready optic.","startYear":2003,"startMonth":12,"endYear":2005,"endMonth":11,"statusDescription":"Completed","principalInvestigators":[{"contactId":208731,"canUserEdit":false,"firstName":"Jay","lastName":"Schwartz","fullName":"Jay Schwartz","fullNameInverted":"Schwartz, Jay","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":103208,"canUserEdit":false,"firstName":"Dave","lastName":"Content","fullName":"Dave Content","fullNameInverted":"Content, Dave","primaryEmail":"David.A.Content@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
