The optics utilized in the laser required a unique set of wavefront specifications because of the extremely high fluences and nonlinear processes that affect the wavefront intensity evolution at these extreme power densities. The optical wavefront specification for these large optics is subdivided into specific spatial frequency regions, the lowest part defined in terms of a RMS wavefront gradient and the higher spatial frequencies limited to not exceed a maximum Power Spectral Density (PSD) defined in greater detail elsewhere.1 In order to verify that these spatial frequency wavefront specifications have been met, the NIF Program has contracted to Veeco Process Metrology (formerly Wyko) a 24-inch phase modulating interferometer capable of extremely high spatial frequency resolution to measure PSD over an operational range of 0.03 to 1.25 mm-1.2 This instrument is a standard Fizeau configuration interferometer with a linearly polarized 650-nm DFB diode laser source and a 1024 x 1024 pixel CCD detector. The optical imaging system has two fixed zoom settings, the lowest corresponding to a spatial viewing area of 431 x 431 mm square centered within the 24-inch diameter fused silica transmission sphere. The high spatial frequency zoom setting provides a 100 mm x 100 mm square aperture with a diffraction limited imaging lens designed to have an MTF > 0.9 at 0.4 mm-1 and MTF > 0.6 at 1.25 mm-1.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","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":"129147635","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}

By Calculating the difference of the measured height at a point and its surrounding areas, it gives the roughness profile nearly independent of vertical vibrations. The height variation of a point and areas are measured from the interfered light intensity variation using a photomultiplier tube and three Si photo diodes arranged on the image plane of the interference microscope. The performance of the profilometer is checked from the roughness measurements of the aluminum substrate for hard disc, the aluminized optical flat, a Si-wafer, and the step standard calibrated by a stylus instrument. As a result, the reproducibility of 0.5nm was verified and the step height at the grain boundary of diamond-turned aluminum disc was measured as about 2.0nm. The errors, caused by the distribution of the slight reflectivity, were reduced by using the dual polarized light interference method. The filtering effect on the profile determined by the sensor arrangement is calculated and corrected by the digital signal processing. By this correction, not only the precise roughness profile but also, the figure profile can be measured independently of vertical vibrations.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"210 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":"124710355","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}

As these high-tech devices become more and more advanced and compact in the recent years, the optical and electronic part, which make up these devices also need to be more accurate and smaller. These parts are commonly ground by loose abrasive lapping and polishing, but these methods have such disadvantages as wastewater processing problem, mechanical damages, wear by scatting abrasives, dirty workplace, and difficulty in using different grains on the same machine. For these reasons, new grinding methods are required as alternatives to the finishing method using loose abrasives. To answer to such needs, the authors have proposed a lap grinding method applying the electrically in-process dressing1) (ELID-lap grinding2)) and are carrying out studies to realize efficient and highly accurate machining. The latest bonding system which is composed of metal and resin was investigated for the ELID-lap grinding in order to improve the grinding quality by addition of the vibration absorbing function during grinding operation3). In this paper, Si which is typical material for X-ray mirror, was ground using metal-resin bonded wheels with different grain sizes, and the grinding characteristics were investigated.","PeriodicalId":354934,"journal":{"name":"Optical Fabrication and Testing","volume":"71 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":"128142576","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}
