Nto Specification
Nto Zoo
Qhov zoo ntawm qhov chaw kho qhov muag yog siv los ntsuas cov yam ntxwv saum npoo ntawm cov khoom siv kho qhov muag thiab npog ntau qhov tsis zoo xws li khawb thiab qhov pits. Feem ntau ntawm cov imperfections saum npoo no yog cov tshuaj pleev ib ce nkaus xwb thiab tsis cuam tshuam rau kev ua haujlwm ntawm lub cev, txawm li cas los xij, lawv yuav ua rau me me poob rau hauv qhov system throughput thiab ib qho kev tawg ntawm lub teeb tawg. Txawm li cas los xij, qee qhov chaw yuav muaj kev cuam tshuam ntau dua rau cov teebmeem no, xws li: qhov chaw nrog cov duab dav hlau, qhov uas cov kev tsis zoo no tuaj yeem tsim kom pom tseeb, thiab cov chaw uas muaj lub zog siab, qhov uas cov imperfections tuaj yeem ua rau lub zog nqus thiab ua rau cov khoom siv kho qhov muag puas. Qhov feem ntau siv specification rau saum npoo zoo yog khawb thiab pitting specification qhia los ntawm MIL-PRF-13830B. Cov npe kos yog txiav txim siab los ntawm kev sib piv cov khawb ntawm ib qho chaw mus rau cov txheej txheem kev khawb los ntawm kev tswj cov teeb pom kev zoo. Yog li, tsis yog piav qhia txog qhov tseeb khawb ntawm qhov ntawd, lub npe kos piv rau cov qauv kos raws li MIL specifications. Cov npe, txawm li cas los xij, cuam tshuam ncaj qha rau cov ntsiab lus lossis qhov pits ntawm qhov chaw. Cov npe ntawm lub qhov yog xam los ntawm kev faib cov kab ntawm lub qhov hauv microns los ntawm 10. Feem ntau qhov khawb qhov tshwj xeeb ntawm 80 thiab 50 yuav suav hais tias yog tus qauv zoo, ntawm 60 thiab 40 yuav yog qhov zoo, thiab nruab nrab ntawm 20 thiab 10 yuav suav tias yog siab precision. zoo.
Nto flatness
p> Nto flatness yog ib hom kev qhia tshwj xeeb uas ntsuas qhov tseeb ntawm qhov chaw, thiab nws yog siv los ntsuas qhov sib txawv ntawm qhov chaw tiaj tus xws li iav, qhov rais,prism, los yog daim iav tiaj tus. Koj tuaj yeem ntsuas qhov sib txawv no siv lub ntsej muag lub ntsej muag lub ntsej muag, uas yog lub dav hlau zoo, siab-precision siv los sib piv cov qauv du. Thaum lub dav hlau ntawm cov khoom siv kho qhov muag nyob rau hauv qhov kev ntsuam xyuas yog muab tso rau ntawm optics, streaks tshwm, cov duab uas qhia txog qhov smoothness ntawm cov khoom kho qhov muag nyob rau hauv kev sim. Yog tias cov streaks sib npaug sib npaug thiab yog cov kab ncaj nraim, ces qhov kev sim qhov muag pom qhov tsawg kawg nkaus raws li qhov siv kho qhov muag tiaj tus siv lead ua. Yog hais tias cov kab txaij yog nkhaus, tus naj npawb ntawm kab txaij ntawm ob txoj kab sib tsoo (ib qho kab sib tw tangent mus rau nruab nrab ntawm kab txaij thiab lwm txoj kab uas hla dhau los ntawm qhov kawg ntawm tib kab txaij) taw qhia rau qhov ua yuam kev smoothness. Qhov sib txawv ntawm qhov smoothness feem ntau yog ntsuas nyob rau hauv cov nqe lus ntawm ripple qhov tseem ceeb (λ), uas yog tsim los ntawm ntau lub wavelengths ntawm qhov chaw kuaj. Ib kab txaij sib raug rau ½ ntawm ib lub wavelength. Ib tug smoothness ntawm 1λ qhia qhov nruab nrab zoo theem; ib tug smoothness ntawm λ / 4 qhia tau hais tias ib qib zoo; thiab ib tug smoothness ntawm λ/20 qhia ib tug high precision zoo theem.
Aperture naj npawb
Tus naj npawb aperture yog ib hom kev qhia tshwj xeeb uas ntsuas qhov tseeb ntawm qhov chaw, uas yog siv tau rau qhov chaw kho qhov muag nkhaus lossis qhov chaw muaj zog. Qhov ntsuas aperture yog zoo ib yam li kev ntsuas flatness nyob rau hauv uas nws muab piv rau saum npoo mus rau qhov chaw siv nrog ib tug collegiate-raug tseeb vojvoog ntawm curvature. Siv tib txoj kev cuam tshuam uas tsim los ntawm qhov sib txawv ntawm ob qhov chaw no, cov qauv cuam tshuam ntawm cov kab txaij yog siv los qhia qhov sib txawv ntawm qhov ntsuas qhov chaw thiab qhov chaw siv. Qhov sib txawv ntawm qhov kev siv yuav tsim ib lub nplhaib hu ua Newton's rings. Qhov ntau lub nplhaib tam sim no, qhov sib txawv ntau dua. Tus naj npawb ntawm qhov tsaus ntuj lossis ci ntsa iab, ntau dua li tag nrho ntawm ob qho tib si tsaus nti thiab ci rings, yog sib npaug rau ob zaug ntawm qhov yuam kev wavelength.
Tsis ncaj ncees lawm
Irregularity yog ib hom kev qhia tshwj xeeb uas ntsuas qhov tseeb ntawm qhov chaw thiab piav qhia qhov sib txawv ntawm cov duab saum npoo los ntawm kev siv lub ntsej muag. Irregularity yog ntsuas tib yam li tus naj npawb aperture. Irregularity yog lub voj kheej kheej kheej kheej tsim los ntawm kev sib piv qhov chaw sim mus rau qhov chaw siv. Thaum lub ntsej muag muaj tus lej aperture ntau dua 5 kab txaij, nws yuav nyuaj rau pom cov duab me me me dua 1 kab txaij. Yog li ntawd, nws yog ib qho kev xyaum qhia kom meej qhov sib piv ntawm tus naj npawb ntawm apertures rau qhov tsis xwm yeem ntawm qhov chaw kom nws yog kwv yees li 5: 1.
Nto tiav/nto roughness
Nto tiav, tseem hu ua nto roughness, yog siv los ntsuas me me irregularities nyob rau hauv ib tug nto. Lawv feem ntau yog tshwm sim los ntawm cov txheej txheem polishing tsis zoo. Cov chaw ntxhib zoo li yuav ua rau muaj kev puas tsuaj ntau dua li qhov chaw du thiab tej zaum yuav tsis haum rau qee qhov kev siv, tshwj xeeb tshaj yog cov siv lasers lossis nyob rau hauv ib puag ncig overheated, vim muaj peev xwm ua rau me me los yog tsis zoo ntawm qhov chaw nucleation. Kev kam rau siab ntau lawm rau saum npoo yog 50Å RMS rau qhov nruab nrab zoo, 20Å RMS rau qhov zoo, thiab 5Å RMS rau qhov zoo.
