Flat optics feem ntau txhais raws li qhov rais, lim, iav thiab prisms. Jiujon Optics tsis yog tsuas yog tsim lub lens kheej kheej xwb, tab sis kuj yog cov optics tiaj tus
Jiujon tiaj tus optical Cheebtsam siv nyob rau hauv lub UV, pom, thiab IR spectrums muaj xws li:
| • Windows | • Cov lim |
| • Daim iav | • Reticles |
| • Encoder disks | • Cov kab |
| • Lub teeb | • Wave daim hlau |
Cov khoom siv kho qhov muag
Thawj thiab qhov tseem ceeb tshaj plaws los xav txog yog cov khoom siv kho qhov muag. Cov yam tseem ceeb muaj xws li homogeneity, kev nyuaj siab birefringence, thiab npuas; tag nrho cov no cuam tshuam cov khoom zoo, kev ua tau zoo, thiab tus nqi.
Lwm yam tseem ceeb uas tuaj yeem cuam tshuam rau kev ua, tawm los, thiab tus nqi suav nrog tshuaj lom neeg, tshuab, thiab thermal zog, nrog rau daim ntawv muab khoom. Cov khoom siv kho qhov muag tuaj yeem sib txawv hauv qhov nyuaj, ua rau kev tsim khoom nyuaj thiab kev ua haujlwm ua tau ntev.
Nto daim duab
Cov ntsiab lus uas siv los qhia cov duab saum npoo yog nthwv dej thiab fringes (ib nrab-yoj) - tab sis nyob rau qee lub sijhawm tsis tshua muaj, qhov chaw tiaj tus yuav raug teev raws li kev siv tshuab hauv microns (0.001 mm). Nws yog ib qho tseem ceeb kom paub qhov txawv qhov txawv ntawm ob qho kev qhia tshwj xeeb: ncov mus rau hav (PV) thiab RMS. PV yog nyob deb ntawm qhov dav dav dav dav dav dav siv niaj hnub no. RMS yog qhov ntsuas qhov tseeb dua ntawm qhov chaw tiaj tus, raws li nws siv rau hauv tus account tag nrho optic thiab xam qhov sib txawv ntawm daim ntawv zoo tagnrho. Jiujon ntsuas optical flats nto flatness nrog laser interferometers ntawm 632.8 nm.
Cov tshuab ob sab
Qhov tseeb aperture, tseem hu ua qhov siv tau aperture, yog qhov tseem ceeb. Feem ntau optics tau teev tseg nrog 85% meej aperture. Rau optics xav tau cov apertures loj dua, yuav tsum tau ua tib zoo saib thaum lub sij hawm tsim cov txheej txheem kom ntev qhov kev ua tau zoo nyob ze rau ntawm ib feem ntawm ntug, ua rau nws yooj yim dua thiab kim rau fabricate.
Parallel los yog wedged
Cheebtsam xws li cov ntxaij lim dej, phaj beamsplitters, thiab qhov rais yuav tsum muaj siab heev parallelism, whereas prisms thiab wedges txhob txwm wedged. Rau qhov uas yuav tsum tau tshwj xeeb parallelism (Jujon ntsuas parallelism siv ZYGO interferometer.
ZYGO Interferometer
Wedges thiab prisms xav tau lub kaum sab xis ntawm qhov xav tau kev ua siab ntev thiab feem ntau ua tiav los ntawm cov txheej txheem qeeb dua siv cov suab polishers. Tus nqi nce ntxiv thaum lub kaum sab xis ua kom nruj dua. Feem ntau, autocollimator, goniometer, lossis lub tshuab ntsuas kev sib koom tes yog siv rau kev ntsuas ntsuas.
Pitch Polishers
Dimensions thiab tolerances
Qhov loj me, nrog rau lwm cov kev qhia tshwj xeeb, yuav hais txog txoj kev ua haujlwm zoo tshaj plaws, nrog rau qhov loj ntawm cov khoom siv. Txawm hais tias tiaj tus optics tuaj yeem ua tau ib qho duab, puag ncig optics zoo li ua tiav qhov xav tau tshwj xeeb dua sai thiab sib npaug. Overly nruj me me tolerances yuav ua tau los ntawm ib tug precision haum los yog tsuas yog ib tug saib xyuas; ob qho tib si muaj kev cuam tshuam tsis zoo rau tus nqi. Bevel specifications yog nyob rau lub sij hawm dhau nruj heev, kuj ua rau nce nqi.
Nto zoo
Qhov zoo ntawm qhov chaw yog cuam tshuam los ntawm cov tshuaj pleev ib ce, tseem hu ua khawb-dig lossis qhov tsis zoo ntawm qhov chaw, nrog rau qhov roughness ntawm qhov chaw, ob qho tib si nrog cov ntaub ntawv pov thawj thiab cov qauv lees paub thoob ntiaj teb. Hauv Asmeskas, MIL-PRF-13830B feem ntau yog siv, qhov ISO 10110-7 tus qauv siv thoob plaws ntiaj teb.
Surface Quality Inspection
Tus kws tshuaj ntsuam xyuas-rau-tus neeg soj ntsuam thiab tus neeg muag khoom-rau-tus neeg siv khoom sib txawv ua rau nws nyuaj rau kev sib txheeb khawb-dag ntawm lawv. Txawm hais tias qee lub tuam txhab sim sib cuam tshuam nrog lawv cov neeg siv khoom cov kev tshuaj ntsuam xyuas (xws li, teeb pom kev zoo, saib qhov cuam tshuam nrog kev sib kis, kev ncua deb, thiab lwm yam), ntau tus neeg tsim khoom lag luam zam qhov teeb meem no los ntawm kev tshuaj xyuas lawv cov khoom los ntawm ib qho thiab qee zaum ob theem. ntawm khawb-dig zoo dua li cov neeg siv khoom tau teev tseg.
Ntau
Rau feem ntau, qhov me me kom muaj nuj nqis, cov nqi ua haujlwm ntau dua ib thooj thiab rov ua dua. Cov khoom qis dhau yuav suav nrog ntau tus nqi, vim tias ib pawg ntawm cov khoom siv yuav tsum tau ua tiav kom ua tiav thiab sib npaug ntawm lub tshuab kom ua tiav cov kev xav tau tshwj xeeb. Lub hom phiaj yog kom ua kom tiav txhua qhov kev tsim khoom lag luam kom txo cov nqi ua haujlwm ntau dua qhov ntau tshaj qhov ua tau.
Ib txheej tshuab.
Pitch polishing, yog cov txheej txheem siv sij hawm ntau dua feem ntau siv rau qhov yuav tsum tau hais qhia txog fractional yoj nto flatness thiab / lossis txhim kho nto roughness. Ob sab polishing yog txiav txim siab, suav nrog cov sijhawm, thaum lub suab polishing tuaj yeem koom nrog hnub rau tib qhov ntau ntawm cov khoom.
Yog hais tias kis tau tus mob wavefront thiab / los yog tag nrho cov thickness variation yog koj thawj specifications, ob-sided polishing yog qhov zoo tshaj plaws, whereas polishing ntawm pitch polishers yog zoo tagnrho yog hais tias reflected wavefront yog qhov tseem ceeb.
