This information has become increasingly valuable because of the emphasis for continuous improvement in optical quality and its corresponding cost and more recently the emergence of CAD/CAM optics manufacturing technology such as Opticam. Radius of curvature and subsurface damage specifications can be tightly controlled while reducing the need for laborious and cost-intensive manufacture of precision optics, including infrared glasses and crystalline structures.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"39 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":"126407834","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}

Consequently both diamond tool manufacturers and machining houses require methods for inspection. The accuracy of the cutting edge which is primarily generated by the intersection of a cylinder/cone with a flat, must be typically 75-150nm. Most test methods rely on observation of the final generated cutting edge via high powered microscope. Unfortunately this means that the diamond tool manufacturer cannot qualify the accuracy of the cylindrical/conical portion of the tool prior to lapping the final flat which generates the final cutting edge. Therefore errors can only be detected on a finished tool which may result in costly re-working.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"109 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":"123846972","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}

A simple model is presented to explain the recent observation that the number of cutter marks N during deterministic microgrinding of spherical components is approximately equal to the ratio of tool rotational rate fT (rpm) to work rotational rate fW for a wide range of these parameters. The model is based on the fundamental assumption that both the tool and the work execute steady-state, forced harmonic oscillations, each at its respective driving frequency, and on the observation that for each revolution of the work, the tool executes fT/fW revolutions.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"65 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":"127595992","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}

Baffles perform a major role in determining the signal-to-noise level of many optical systems. While a few commercially available baffle materials meet optical requirments, current industrial baffle materials do not meet survivability and endurability needs; i.e, thermal, mechanical, and chemical stability requirements. The major problem is the generation of particles from the baffle surfaces during transport and operation which degrade the image quality.","PeriodicalId":142307,"journal":{"name":"Optical Fabrication and Testing Workshop","volume":"79 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":"114635061","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}
