1.49 CR39 I-Semi-finished Spectacle Lens Blanks
Yini Engenziwa I-Semi Finished Lens Blanks?
Amayunithi okukhiqiza amalensi e-Spectacle aguqula amalensi acishe aqedwe abe amalensi aphelile ngokuya nezici ezinembile zencwadi kadokotela.
Umsebenzi wokwenza ngokwezifiso wamalabhorethri usenza sikwazi ukuhlinzeka ngokuhlukahluka okubanzi kokuhlanganiswa kokubona ngezidingo zabagqoki, ikakhulukazi ngokuphathelene nokulungiswa kwe-presbyopia. Amalabhorethri anesibopho sokubeka phezulu (ukugaya nokupholisha) kanye nokunamathisela (ukufaka umbala, ukunqanda ukuklwebheka, okunqanda ukukhanyela, okulwa nodaka njll.) amalensi.
Kungani Kufanele Ukhethe I-CR-39 Optical Lens?
I-Crystal Vision (CR) amalensi ekhwalithi ephezulu enziwe enye yezinkampani zamalensi ezinkulu emhlabeni.
I-CR-39, noma i-allyl diglycol carbonate (ADC), i-polymer yepulasitiki evame ukusetshenziswa ekwenzeni amalensi engilazi yamehlo.
Isifinyezo simelela “i-Columbia Resin #39”, okwakuyifomula yama-39 yepulasitiki ebeka i-thermosetting eyakhiwa iphrojekthi ye-Columbia Resins ngo-1940.
Iphethwe yi-PPG, le nto iguqula ukwenziwa kwamalensi.
Ingxenye esindayo njengengilazi, mancane kakhulu amathuba okuthi ingaphahlazeka, kanye nekhwalithi yokubona icishe ilingane nengilazi.
I-CR-39 iyashiswa futhi ithululelwe ekubunjweni kwengilazi yekhwalithi ye-optical - ukulungisa izimfanelo zengilazi eduze kakhulu.
a) Ezomnotho
b) Ukukhanya
c) Ukumelana ne-Shatter
d) Ingafakwa umbala futhi inamekwe
e) Ukuvikelwa kwe-UV
Iyini i-lens ye-freeform?
Ilensi ye-freeform ngokuvamile inendawo yangaphambili eyindilinga kanye nendawo engemuva enezinhlangothi ezintathu eyinkimbinkimbi ehlanganisa incwadi yesiguli. Esimeni se-lens eqhubekayo ye-freeform, i-geometry yangemuva yangemuva ihlanganisa umklamo oqhubekayo.
Inqubo ye-freeform isebenzisa amalensi ayindilinga acishe aqedwe atholakala kalula kuhlu olubanzi lwamajika ayisisekelo nama-indices. Lawa ma-lens enziwe ngomshini ngokunembile ohlangothini olungemuva kusetshenziswa izinto zesimanje ezikhiqizayo nokupholisha ukuze kwakheke indawo eqondile kadokotela.
• indawo engaphambili iyindawo elula eyindilinga
• indawo engemuva iyindawo eyinkimbinkimbi enezinhlangothi ezintathu
Ubuchwepheshe be-freeform lens
• Inikeza ukuguquguquka ukuze unikeze uhla olubanzi lwemikhiqizo yezinga eliphezulu, ngisho nelabhorethri yokubona encane
• Idinga kuphela isitokwe sama- semi-feed sphere kunto ngayinye kunoma yimuphi umthombo wekhwalithi
• Ukuphathwa kwelebhu kwenziwa lula ngama-SKU ambalwa kakhulu
• Indawo eqhubekayo iseduze neso - ihlinzeka ngezindawo zokubuka ezibanzi ephaseji nendawo yokufunda
• Ikhiqiza kabusha ngokunembile umklamo oqhubekayo ohlosiwe
• Ukunemba kwencwadi kadokotela akunqunyelwe izinyathelo zamathuluzi ezitholakala elabhorethri
• Ukuqondanisa okunembile kwencwadi kadokotela kuqinisekisiwe
