Hopkins was polished with a 1.2-m stress lap on the Large Optical Generator at the Steward Observatory Mirror Lab. Problems during the last few months of polishing led to the development of a system for monitoring the drag forces on this lap. Records of the drag forces during each stroke were then used to compute an effective drag coefficient as well as the frictional power dissipated per unit area of mirror as a function of radius. While the glass removal rate was found to track the observed distribution of expended frictional energy quite nicely, the system turned out to be even more valuable as a tool for identifying anomalous drag conditions before they put a significant imprint on the mirror.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"5 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":"125594775","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 scope of this latest COM machine development project was to design and build a cost effective, high precision machine that would deterministically microgrind aspheric optical components in brittle optical glass materials. The ground surfaces had to be compatible with COM and QED-developed magnetorheological finishing processes. Moore Tool’s design goals were to design a machine dedicated to grinding aspheres up to 100mm in diameter in a production environment (see page 2 for machine specifications). With the new capabilities of this grinder and the magnetorheological finishing process, COM’s goal was to demonstrate a 10x reduction in the cost of asphere fabrication.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"7 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":"126022146","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}

This paper will describe the various techniques developed to mold glass lenses, with application examples given for each method. A worldwide survey of known commercial availability and very recent developments at Kodak to demonstrate the potential of the precision glass molding technology are reviewed. Precision Glass Molding (PGM) at Kodak has been extended from Spherical and Aspheric lens molding to non-symmetrical optics. Even more recently radiation hardened glasses, glass-based infrared materials, and laser glasses have been molded. Since the molded optic precisely replicates the tool, features on the optic can be utilized to more easily align aspheric and non-symmetrical optical elements into the optical system. Transmitted wavefronts of better than 0.05 waves rms are achieved with a single aspheric lens. Overall performance of the single element lens system is typically superior to a three-element spherical lens system when field performance, magnification control, and actual N.A. control are considered.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"190 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":"121727573","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}

Aspheric null lens tests suffer from an inability to use reference subtraction or absolute calibration techniques to separate rotationally symmetric aberrations that exist between the test setup and the aspheric surface. Furthermore, zonal positioning errors that exist when imaging from surface to camera can be accounted for with conventional tests, but the zonal location of irregularities is crucial in the correction of aspheric components during the fabrication process. The interferometric null test bench must be designed, built, and characterized with high precision to achieve accurate aspheric surfaces.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"70 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":"131010372","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}

Then the accuracy is limited by the reference mirror and optical elements been used. We use the modified Fizeau interferometer setup. A second beam splitter is placed in the focal plane of a diverger lens. The reflection beam by this B.S. is regarded as reference wave. Then the setup will have three merits: (1) The two beams go through almost the same position at each optical element, so the quality of the optical elements such as the diverger lens and the first beam splitter can be neglected. (2) The second beam splitter (now the reference surface) is easily to be made high quality because of the region been used is very small. So we may consider the reference wave as perfect. (3) It is easily to control the diffraction order to obtain the interference pattern. Besides, we describe the real interference pattern by computer based on analytic equations and calculate the exact position of the interference fringes as in the conventional hologram. Therefore, the plot of the CGH is pure interferometric type.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"120 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":"133825698","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}
