Keck Observatory Primary Mirror is a coordinated effort in balancing production manufacturing with state of the art large mirror fabrication. The basic concept of production manufacturing is to reduce the manufacturing steps to their fundamentals by putting the quality into the machinery and fixturing allowing as little recurring manhour input as possible. The state of the art large mirror fabrication, on the other hand, usually involves the minimum in machinery and tooling as possible and using as much human skill input as necessary. The manufacturing and testing conducted at Itek is the result of the compromises that ensues when drawing that fine line between two very broad concepts.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114812163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interference fringes detected reveal the flatness of the cavity. In the traditional three-flat method,1,2 the flats are compared in pairs. By rotating the flats with respect to each other, the exact profiles along several diameters of each flat are obtained. A method with more flats and more combinations has been proposed.3 However, with both methods, only the profiles along some straight lines can be solved. Several methods4-8 have been proposed to measure the flatness of the entire surface. These methods involve tremendous least squares calculations. Thus, the fine structure of the surface tends to disappear.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129402212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the effective methods of solving this problem is precise pressing (or molding) of glass blanks, Blanks placed between the male and female molds were heated and pressed 1,2. Molded micro elements do not demand mechanical treatment. But in this case, practically, a very complicated problem is substituted for only slightly complicated one. It means that considerable efforts are made to prepare male and female mold surfaces. They are precise mechanical treatment, the coating of surfaces by high temperature resistant multi layer coats and so on. At the beginning of our study the main question under investigation was: \"Can we develop the technique that allows to produce micro optical elements with spherical and aspherical surfaces without or with simplest mechanical treatment of both the glass blanks and the molds?” In this talk two techniques of fabrication curvilinear surfaces of micro optical elements without mechanical treatment have been considered.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128234793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reveal the subsurface system of fractures acid etching has been used to open up the fractures for measurement.1,2 This method, however, is unreliable to varying degrees due to non-uniform etching rates at the top and bottom of the fracture. Moreover, most information on the structure of the fractures themselves is lost in the process. We have developed a method which also uses acid etching but uses specially prepared substrates that reveal very clearly the structure and depth of the fractures. Figure 1 depicts how the substrates are prepared.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121198063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
