1.49 CR39 Semi-tiav Spectacle Lens Blanks
Dab tsi Semi Finished Lens Blanks tuaj yeem ua tau?
Spectacle lo ntsiab muag ntau lawm units uas hloov cov lo ntsiab muag semi-tiav rau hauv cov lo ntsiab muag tiav raws li cov yam ntxwv ntawm cov tshuaj.
Kev ua haujlwm kho kom haum ntawm lub chaw soj nstuam tso cai rau peb muab ntau qhov sib txawv ntawm kev sib txuas kho qhov muag rau cov neeg siv xav tau, tshwj xeeb tshaj yog hais txog kev kho tus mob presbyopia. Laboratories yog lub luag hauj lwm rau surfacing (sib tsoo thiab polishing) thiab txheej (xim, anti-scratch, anti-reflective, anti-smudge thiab lwm yam) lub lo ntsiab muag.
Vim li cas thiaj xaiv CR-39 Optical Lenses?

CR-39, los yog allyl diglycol carbonate (ADC), yog cov yas polymer feem ntau siv los tsim cov tsom iav qhov muag.
Cov ntawv luv luv yog "Columbia Resin #39", uas yog 39th qauv ntawm cov yas thermosetting tsim los ntawm Columbia Resins project hauv xyoo 1940.
Muaj los ntawm PPG, cov khoom siv no yog revolutionizing lens ua.
Ib nrab hnyav li iav, tsis tshua muaj kev tawg, thiab kho qhov muag zoo yuav luag zoo li iav.
CR-39 yog rhuab thiab nchuav rau hauv cov iav zoo pwm - kho qhov zoo ntawm iav zoo heev.
a) Economic
b) Lub teeb

Lub lens freeform yog dab tsi?
Lub lens freeform feem ntau muaj lub ntsej muag kheej kheej thiab ib qho nyuaj, peb sab nraub qaum uas suav nrog tus neeg mob cov tshuaj. Nyob rau hauv cov ntaub ntawv ntawm ib tug freeform progressive lens, rov qab nto geometry muaj xws li kev txhim kho tsim.
Cov txheej txheem freeform siv semi-tiav kheej kheej kheej kheej lo ntsiab muag uas tau yooj yim muaj nyob rau hauv ntau yam ntawm lub hauv paus nkhaus thiab indices. Cov lo ntsiab muag no tau raug machined nyob rau sab nraub qaum siv lub xeev-ntawm-tus-kos duab tsim thiab polishing cov cuab yeej los tsim cov ntawv sau npe.
• sab pem hauv ntej yog ib qho yooj yim kheej kheej nto
• sab nraub qaum yog ib qho chaw peb sab
Technology rau freeform lo ntsiab muag
• Muab qhov yooj yim los muab ntau yam ntawm cov khoom qib siab, txawm tias qhov chaw kuaj qhov muag me me
• Tsuas yog yuav tsum muaj cov khoom lag luam ib nrab ua tiav hauv txhua yam khoom los ntawm txhua qhov chaw zoo
• Kev tswj chaw kuaj sim ua kom yooj yim nrog SKUs tsawg dua
• Kev loj hlob nto nyob ze rau ntawm lub qhov muag - muab kev pom dav dav hauv txoj kev hauv tsev thiab thaj chaw nyeem ntawv
• Tsim kom muaj tseeb cov qauv tsim ua tiav
• Kev tshuaj xyuas qhov tseeb tsis txwv los ntawm cov kauj ruam uas muaj nyob hauv chav kuaj
