Fused Silica is a synthetic, amorphous glass manufactured by a flame hydrolysis process. It differs from more conventional optical glasses in that it consists of nearly 100% pure silicon dioxide and therefore features exceptional transmittance in the ultraviolet as well as a very low coefficient of thermal expansion. While conventional optical glasses are manufactured by melting batches of the correct mineral constituents, fused silica is made by a chemical process in which silicon tetrachloride, natural gas and oxygen are combined in a burner and droplets of pure SiO2 are caused to precipitate.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"75 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":"132180038","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}

It is a compact, self-contained, easy to align and operate, next generation optical shop instrument. The principle applications for an infrared interferometer are: 1) inspection of infrared materials in transmission for index homogeneity and internal defects, 2) interferometry of surfaces, such as an asphere, whose slopes are too steep for the fringes to be resolved by a visible interferometer, and 3) interferometry of surfaces that are too rough to be tested at visible wavelengths. The advantages of operating an infrared interferometer in the phase-shifting mode are: 1) improved wavefront phase measurement accuracy and resolution 2) the measurement is independent of the beam irradiance distribution and the interferogram fringe contrast, and 3) the wavefront can be sampled and analyzed rapidly over a large two dimensional area.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"18 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":"132627632","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 structures that support the crank and far end of the trombone take up easily as much floor space as the polishing table itself. For a 2 or 3 m polisher this loss of floor space can be overlooked. For an 8 m polisher we had to see if there wasn't a more efficient design.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"407 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":"115560046","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}
