Zvigadzirwa zvepurasitiki uye jekiseni kuumbwa ndiro hwaro hwekuti miniaturized lenses. Chimiro chemhando yepurasitiki chinosanganisira lens zvinyorwa, lens barrel, lens gomo, spacer, shading pepa, dzvinyiriro ring, nezvimwewo.

Kune akati wandei marudzi e lens zvinhu zvemapurasitiki lenses, ese ayo ari epurasitiki (yakakwira molecular polymer). Ivo ndivo termoplastics, mapurasitiki anopfava uye vanova epurasitiki pavakapururudza, vakaomesa kana vakadzvanywa kana vakapfava kana vapfadzaniswa zvakare. Shanduko yemuviri inoburitsa shanduko yekuchinja pakati pemvura uye nyika dzakasimba dzichishandisa kupisa uye kutonhora. Zvimwe zvigadzirwa zvakagadzirwa pakutanga uye zvimwe zvitsva. Zvimwe zvinongedzo-zvinangwa zvekushandisa mapurasitiki, uye zvimwe zvinhu zvinogadzirwa zvine hunyanzvi zvepurasitiki zvemapurasitiki zvemapurasitiki, izvo zvinonyanya kushandiswa mune dzimwe nzvimbo dzepfungwa.

Mune magadzirirwo emitambo, tinogona kuona mamakisi emakambani akasiyana-siyana, akadai (K26r, APL5015, OKP-1 uye zvichingodaro. Ivo vese ndevamwe verimwe mhando yezvinyorwa zvepurasitiki, uye mhando dzinotevera dzakajairika, uye isu tichavagadzirisa maererano nenguva yavo yekuita:

Iyo epurasitiki lenses

• L PMMA / Acrylic:Poly (methyl methacrylate), polmethyl methacrylate (plexiglass, acrylic). Nekuda kwemutengo wayo wakachipa, kuendesa kumusoro, uye simba rakakura, pmma ndiyo yakajairika girazi kutsiva muhupenyu. Mazhinji emapurasitiki anoonekera akagadzirwa naPmma, senge mahwendefa akajeka, zvipfeko zvinooneka, uye zvidiki zvidiki. Lens etc. PMMA yave yakawandisa-yakagadzirwa kubva kuma1930s.
• PS:Polystyrene, polystyrene, isina ruvara uye yakajeka thermplasticastic, pamwe nepurasitiki yeinjiniya, iyo yakatanga kugadzirwa kwakawanda muma1930s. Mazhinji emabhokisi machena mavara uye mabhokisi ekudya kwemasikati anozivikanwa muhupenyu hwedu akagadzirwa nePP PS.
• PC:Polycarbonate, polycarbonate, zvakare isina ruvara uye yakajeka Amorphous Thermoplasticas, uye zvakare ndiyo general-general plastiki. Yakanga yakangogadziriswa mu 1960s. Iko kukonzeresa kuramba kwePC zvinyorwa zvakanaka, zvizhinji zvekushandisa zvinosanganisira mabhegi emvura anodzingwa, maGoggles, nezvimwe.
• l COP & Coc:Cyclic olefin polymer (cop), cyclic olefin polymer; Cyclic olefin Copolymer (Coc) Cyclic Olefin Copolymer ane Chimiro cheCyclic, Carclic Hydrocarbons ) Nemamwe mamorekuru (senge ethylene). Hunhu hweCOP uye Coc zvakada kufanana. Izvi zvinyorwa hutsva. Pakatanga kugadzirwa, zvainyanya kutariswa kune zvimwe zvekurondedzerwa zvekushandisa. Izvozvi zvakanyatsoshandiswa mufirimu, Optical lens, kuratidza, kurapwa (kurongedza bhodhi) maindasitiri. Cop akapedza kugadzirwa kwemaindasitiri kunhivi dza1990, uye coc akapedza kugadzirwa kwemaindasitiri pamberi 2000.
• l o-pet:Optical Polyester Optical Polyester filly, O-PET YAKAITWA MU Osaka mune iyo 00s.

Kana uchiongorora zvinhu zvekunze, isu tinonyanya kunetseka nezvinhu zvavo zvekunze uye zvemakaniki.

• Refractivation Index & Kupararira

Refractive Index uye Kupararira

Zvinogona kuoneka kubva kuhunyanzvi uhwu hwekuti zvinhu zvakasiyana zvekupembera zvepurasitiki zvinowira mukati mevakapetwa kaviri: Rimwe boka rakakwirira rextive index uye kuparadzaniswa kwakanyanya; Rimwe boka rakadzika rextive index uye kuparadzaniswa kwakaderera. Kufananidza yakasarudzika mhando yeiyo indekisi yekudzora uye kupararira kwegirazi, isu tichaona iyo yakasarudzika huwandu hwenzvimbo yekudzora yezvinhu zvepurasitiki ndeyekunyanyisa, uye zvese zvekunze zvemapurasitiki zvinhu zvine yakaderera index. Kazhinji kutaura, huwandu hwesarudzo dzemidziyo yepurasitiki ndeyekunyarara, uye kune angangoita gumi kusvika ku10 ekutengesa mamakisi emitambo, ayo anonyanya kukonzera rusununguko rwekugadzirwa kwechokwadi maererano nezvinhu.

Refractive Index inosiyana neWavelength

Refractive Index inoshanduka neTembiricha DN / DT: Tembiricha yekudziya yeiyo Refractive yePlastics Plastics Plastics Plastics Plastics Plastics Plastics Plastics Plastics Plastics Plastics Plastics Plastics Semuenzaniso, kune wavelength of 546nm, -20 ° C kusvika 40 ° C. ° C, The DN / DT Kukosha kwezvinhu zvepurasitiki ndeye -8 kusvika -14x10 ^ -5 / ° C, uregei, kukosha kwegirazi regirazi NBK7 ndeye 3X10 ^ -6 / ° C.

• Transmittance

Kutapurirana

Achitaura nezve uyu mufananidzo, akawanda emifananidzo mapurasitiki ane transmittance yeanopfuura 90% mune inoonekwa yechiedza chechiedza; Ivo zvakare vane kutapurirana kwakanaka kwezvinhu zvisingaverengeki ve 850nm uye 940nm, izvo zvinowanzoitika mumutengi magetsi. Iko kuendesa kwePurasitiki zvinhu zvinoderedza zvakare kune imwe nhanho nenguva. Chikonzero chikuru ndechekuti mapurasitiki anotora iyo Ultraviolet ravy muzuva, uye iyo ma molecular ketani yekushambadzira uye kuyambuka-chinongedzo, zvichikonzera shanduko mumuviri uye makemikari zvivakwa zvemuviri uye zvemakemikari. Iyo yakanyanya kujeka macroscopic kuratidzwa ndiyo yero yero yezvinhu zvepurasitiki.

• Kushungurudzika Birefingence

Lens Refraction

Kushushikana Birefringence (Birefrince) inzvimbo yezvinhu zvinhu zvekushandisa. Iyo indekisi yekudzora yezvinhu zvine chekuita neyakagadziriswa nyika uye kutungamira kwekuparadza kwechiedza chechiedza. Zvishandiso zvinoratidzira indices dzakasiyana dzekuratidzira kune dzakasiyana polarization nyika. Kune mamwe masystems, iyi yekudzora index kutsauka idiki uye haina kukanganiswa kukuru pane system, asi kune mamwe masisitimu akasarudzika, kutsauka uku kwakakwana kukonzera kusvibiswa kwakakura kwekuita kwehurongwa.

Zvigadzirwa zvepurasitiki ivo pachavo havana hunhu hunhu, asi jekiseni kuumbwa kwemapurasitiki vachasuma kushushikana kushushikana. Chikonzero chikuru ndechekuti kushushikana kwakaunzwa panguva yekuumbwa kwejekiseni uye kurongeka kwepurasitiki macrosticcules mushure mekutonhora. Iko kunetseka kunowanzo kuvezwa pedyo neiyo jekiseni chiteshi, sezvakaratidzwa mumufananidzo pazasi.

Iyo general dhizaini uye nhungamiro yekugadzira ndeye kuderedza kushushikana kwekunetseka mune iyo Optical inoshanda ndege, iyo inoda dhizaini yeiyo lens chimiro, jekiseni inoumba mold uye kugadzirwa paramita. Pakati pezvimwe zvinhu, PC zvinyorwa zvinonyanya kufarirwa kushushikana (kanenge kagumi zvakakura kupfuura PMMA zvinhu), uye COP, COC zvinhu zvine kuderera kushushikana kwekunetseka.
