Kev hloov khoom siv, Curve Generation, CNC Sib Tsoo thiab Polishing
Firstly raw khoom yog hloov dua siab tshiab rau hauv approximate zoo ntawm lub lens, qhov no minimizes lub sij hawm siv tshem tawm cov khoom tom qab nyob rau hauv tus txheej txheem.
Thawj ntawm ob peb kauj ruam sib tsoo rau nkhaus optics yog nkhaus tiam, txheej txheem sib tsoo ntxhib uas ua rau qhov dav dav spherical curvature ntawm lub lens. Cov kauj ruam no yog txhawm rau tshem tawm cov khoom siv thiab tsim qhov zoo tshaj plaws-haum lub vojvoog kheej kheej ntawm ob sab ntawm lub lens, lub vojvoog ntawm curvature yog kuaj thiab tswj siv lub spherometer thaum lub sijhawm ua haujlwm.
Txhawm rau npaj rau lub computer suav nrog kev tswj hwm los yog CNC sib tsoo, ib feem ntawm lub tog raj kheej yuav tsum tau txuas nrog cov hlau tuav hauv cov txheej txheem hu ua thaiv. Lub sub-aperture asphere sib tsoo cov cuab yeej uas muaj me me ntawm pob zeb diamond yog siv los tshem tawm cov khoom thiab tsim cov aspheric nto. Txhua kauj ruam sib tsoo siv cov pob zeb diamond zoo zuj zus.
Cov kauj ruam tom ntej tom qab ob peb qhov kev sib tsoo yog CNC polishing, lub cerium oxide polishing compound yog siv los ntawm cov kauj ruam no txhawm rau tshem tawm qhov kev puas tsuaj ntawm cov av thiab hloov cov av saum npoo mus rau polished uas yuav raug kuaj xyuas hauv lub tshuab ntsuas kom paub meej. lens kom ua tau raws li qhov chaw zoo.
Nyob rau hauv cov txheej txheem metrology yog siv los saib xyuas qhov nruab nrab thickness, aspheric nto profile & lwm yam tsis thiab ua rau tus kheej kho ntawm kev sib tsoo thiab polishing cov kauj ruam.
CNC Sib Tsoo thiab Polishing vs Pa Sib Tsoo thiab Polishing
Paralight Optics siv ntau tus qauv ntawm lub khoos phis tawj suav nrog los yog CNC grinders thiab polishers, txhua qhov yog ua kom zoo rau ntau qhov sib txawv ntawm qhov ntau thiab tsawg, ua ke peb muaj peev xwm tsim lub lens diameters ntawm 2mm txog 350mm.
Lub tshuab CNC tso cai rau kev tsim khoom ruaj khov thiab tus nqi tsim nyog, txawm li cas los xij cov pa grinders thiab polishers tuaj yeem ua tau los ntawm cov kws tshaj lij & cov kws tshaj lij nrog kev paub nplua nuj thiab tsim cov lo ntsiab muag zoo heev.

Conventional Grinders thiab Polishers
Centering tshuab
Paralight Optics siv ob qho tib si Kev Taw Qhia Centering Tshuab thiab Nws Pib Centering Tshuab los ntawm kev sib tsoo nws txoj kab uas hla sab nraud, peb muaj peev xwm ua tiav qhov nruab nrab mus txog 30 arcseconds, yooj yim rau 3 arcminutes specification rau feem ntau ntawm peb cov optics. Lub centration yog sim tom qab ua qhov chaw kom ntseeg tau tias cov khoom siv kho qhov muag thiab cov axes zoo sib xws.
