Various fixturing techniques have been used during diamond machining to minimize or duplicate the strain that the part will be subjected to during use. These techniques include: three-point support, one-point support, potting, collet chucking, and vacuum chucking. During the production of a 15-inch-diameter reflaxicon, its two components, a ring axicon and center axieon, were assembled in tangent mounts and supported using a vacuum chuck. The tangent mount reduced the fixturing strain by increasing the distance the strain must propagate through, and by increasing the rigidity of each component relative to the spindle fixture. Non-flatness error of approximately 40 μin (1 μm) in the support flange of the tangent mount resulted in less than 2 μin (.05 μm) distortion in the optical surface.","PeriodicalId":170034,"journal":{"name":"Workshop on Optical Fabrication and Testing","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129441225","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}

We propose to use a multiple subaperture interferometric test modeled after analogous techniques used in full aperture testing of large optical systems1. A spherical harmonic base set of polynomials for full sphere descriptions is developed, together with the numerical methods for fitting these polynomials to obtain the aberration coefficients over the spherical surface. The physical interpretation of the lower order terms with respect to OPD errors for a spherical body are discussed and demonstrated using three-dimensional graphics representations. A computer simulation of the multiple subaperture technique for full spheres is utilized in an analysis of test accuracy as a function of various test design parameters (subaperture size, number of subapertures, subaperture tilt errors, inter-subaperture phasing errors, etc.). The results of the simulation suggest that optical testing of full spheres is feasable and has the potential for increased speed, accuracy, and surface preservation as compared to direct physical methods.","PeriodicalId":170034,"journal":{"name":"Workshop on Optical Fabrication and Testing","volume":"32 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":"124809360","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}

Change of reference curvature for minimum zonal error is effected by changing each shift by the same amount. Errors are exact to third-order for conic surfaces. The method is especially helpful when many tests must be made in the figuring process. Formulas are derived and an example is given, using both arithmetical and graphical error adjustment.","PeriodicalId":170034,"journal":{"name":"Workshop on Optical Fabrication and Testing","volume":"57 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":"123876513","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}
