Bandhiggani waxa uu leeyahay 758 bandhige, oo ay ku jiraan 158 bandhigayaal caalami ah oo ka kala socda 18 waddan iyo gobollada adduunka oo dhan.iyaga ka mid ah, waxaa jira in ka badan 20 "waji cusub" ee madxafka caalamiga ah, oo ku saabsan 12%;Waxaa jira ku dhawaad 80 bandhigeyaal cusub oo ku jira daarta gudaha, oo ka dhigan 15% wadarta guud.Wajiyo cusub iyo saaxiibo hore, kulan farxad leh!
Iyada oo aagga bandhiggu ka badan yahay 70,000 mitir oo laba jibbaaran, in ka badan 10 nooc oo alaabooyin horumarsan ah iyo guulaha tignoolajiyada sida muraayadaha indhaha, muraayadaha indhaha, muraayadaha indhaha, qalabka iyo qalabka, alaabada durugsan iyo nidaamyada software ayaa si buuxda loo soo bandhigay.Mawduucyada "aragtida mustaqbalka" oo si qoto dheer loo nashqadeeyay iyo goobaha kaadhadhka wakhtiga ayaa ku yaal dhammaan Xarunta Bandhigga Bandhigga, oo dadka u noqda cimilo.
Intii lagu guda jiray bandhigga 3-da maalmood ah, ururka iyo shirkadaha ka qaybgalaya waxay qabteen ku dhawaad 30 hawlood oo miisaan kala duwan leh isla muddadaas, oo ku lug leh horumarkii ugu dambeeyay ee ka hortagga iyo xakamaynta myopia, ka hortagga iyo tarjumaadda siyaasadda myopia, caafimaadka aragga ee qaranka, qaabka iyo muraayadda muraayadda. siidayn cusub iyo mowduucyo kale oo badan, hodan iyo xog faahfaahsan, si ay u caawiyaan booqdayaasha inay ku raaxaystaan fahamka hal-joojin ee tignoolajiyada goynta iyo horumarka warshadaha ee indhaha.
Shirkado badan oo gudaha iyo dibadda ah ayaa ka qaybqaatay bandhigga muraayadaha xabagta.
Lens resin waa nooc ka mid ah muraayadaha ka samaysan walxaha organic, gudaha waa qaab-dhismeedka silsilad polymer ah, isku xidhan iyo qaab-dhismeedka shabakad saddex-cabbir ah, qaab-dhismeedka intermolecular waa yara dabacsan, iyo meel bannaan oo u dhexeeya silsiladaha molecular soo saari kartaa barakac qaraabo ah.Gudbinta iftiinka waa 84% -90%, gudbinta iftiinka waa wanaagsan tahay, iyo muraayadda resin indhaha ayaa leh iska caabin xoog leh.
Lens resin waa nooc ka mid ah walxaha organic, gudaha gudaha waa qaab-dhismeedka silsiladda polymer, isku xiran iyo qaab dhismeedka shabakad saddex-cabbir ah, qaab-dhismeedka intermolecular waa mid dabacsan, iyo booska u dhexeeya silsiladaha kelli wuxuu soo saari karaa barokac qaraabo ah.Gudbinta iftiinka waa 84% -90%, gudbinta iftiinka waa wanaagsan tahay, iyo muraayadda resin indhaha ayaa leh iska caabin xoog leh.
Lens resin waa nooc ka mid ah muraayadaha indhaha ee laga sameeyay xabagta.Waxaa jira noocyo badan oo qalab ah, oo marka la barbardhigo muraayadaha muraayadda, waxay leedahay faa'iidooyinkeeda gaarka ah:
1. Iftiin.Muraayadaha resin guud waa 0.83-1.5, iyo muraayadaha indhaha 2.27 ~ 5.95.
2, iska caabin xoogan oo saameyn leh.Saamaynta caabbinta muraayadaha resinka guud ahaan waa 8 ~ 10kg/cm2, taas oo ah dhawr jeer ka muraayadda, markaa ma fududa in la jebiyo, badbaado leh oo waara.
3, gudbinta iftiinka wanaagsan.Gobolka muuqda, gudbinta lenska resin waxay la mid tahay tan dhalada.Gobolka infrared, wax yar ka sarreeya muraayadda;Gobolka ultraviolet, gudbinta ayaa hoos u dhacda marka mawjada dhererkeedu hoos u dhaco, iyo iftiinka hirarka dhererkiisu ka yar yahay 0.3um ayaa si buuxda u nuugay.
4, qiimo jaban.Muraayadaha wax lagu mudayo ee la isku duro, kaliya waxay u baahan yihiin in la soo saaro caaryo sax ah, waa la soo saari karaa tiro badan, taas oo badbaadinaysa kharashyada habaynta iyo waqtiga.
5, dabooli kara baahiyaha gaarka ah.Tusaale ahaan, wax soo saarka muraayadaha aspherical ma aha mid adag, iyo muraayadaha muraayadaha ayaa adag in la sameeyo.
Dood
Tilmaanta refractive-ka oo laablaaban
Waa saamiga sinaha ee xagasha iftiinka la kala qaado ee lenska iyo iftiinka dhacdada iyo xagasha iftiinka dhacdada.Qiimaheedu guud ahaan waa inta u dhaxaysa 1.49 iyo 1.74.Isla darajada, heerka sare ee index refractive, lens khafiif ah, laakiin sare index refractive maadda, aad u daran kala firdhiso.
U-laabashada iska caabinta xagashada
Waxa loola jeedaa heerka dhaawaca ee gudbinta iftiinka ee dusha muraayadda ee hoos yimaada ficilka xoogagga dibadda.xoqitaanka muraayadda ayaa ah arrin muhiim ah oo saameeya nolosha adeegga iyo saameynta muuqaalka muraayadda.Qiimaha ceeryaamada aadka loo isticmaalo (Hs) ee Shiinaha waxay tilmaamaysaa in qiimihiisu guud ahaan u dhexeeyo 0.2-4.5, iyo inta hoose ee ka wanaagsan.Habka BAYER waxaa caadi ahaan looga isticmaalaa wadamada shisheeye, qiimihiisana waa inta u dhaxaysa 0.8-4, sare ayaa ka fiican.Caadi ahaan loo yaqaan muraayadaha resin ee adag, caabbinta xoqan ayaa ka fiican muraayadaha resin-ga guud.
Isku laablaabida heerka goynta UV
Sidoo kale loo yaqaan qiimaha UV, waa tilmaame muhiim ah si loo qiimeeyo xannibaadda waxtarka leh ee shucaaca ultraviolet ee muraayadda.Qiimaheedu waa inuu ka weyn yahay 315nm, guud ahaan ka weyn yahay 350nm kana yar 400nm.Muraayada UV400, oo inta badan laga maqlo dukaamada indhaha, ayaa si wax ku ool ah u xannibi kara shucaaca ultraviolet.Intaa waxaa dheer, waxa kale oo suurtagal ah in lagu daro filimka ilaalinta shucaaca ee lenska resin.
Isku-laabashada gudbinta iftiinka
Saamiga qaddarka iftiinka ee muraayaddu saadaalisay iyo inta shilka iftiinka.Markasta oo ay sare u kacdo gudbinta, ayaa lensku sii cadeynayaa.
Lanbarka abbe
Waxaa loo isticmaalaa in lagu muujiyo tusmada saamiga rogan ee awoodda kala firdhisan ee walxaha hufan, waxaana loo isticmaali karaa tixraac ahaan xallinta midabka qalalan ee iftiinka muuqda ee muraayadda.Qiimaheedu waa inta u dhaxaysa 32 iyo 60, iyo marka uu sareeyo nambarka Abbe ee muraayadda, waa yaraanta qallooca.
Iska caabbinta laalaabida saamaynta
Waxa loola jeedaa xoogga farsamada ee muraayadda si uu u adkaysto saamaynta.Saamaynta iska caabbinta muraayadaha resin-ka ayaa ka xoog badan kuwa muraayadaha muraayadda, iyo xitaa qaar ka mid ah muraayadaha resin-ka ayaa ah kuwo aan jabin karin.
Weli waxaa jira faa'iidooyin badan oo lensiska resin-ka ah, haddii kale hadda ma noqonayso muraayadda ugu isticmaalka badan.Muraayadaha resin sidoo kale waa la dahaar karaa, caaggu waa xoogaa xoog badan yahay, aad ayuu uga fiican yahay muraayadaha kale, laakiin tayada muraayadaha resin weli aad bay u kala duwan yihiin, markaa marka aan isku dhejino muraayadaha, weli waa inaan si taxadar leh u doorannaa, si aan u dooranno muraayadaha saxda ah. anaga.
