Maonekedwe a ma lens amatenga gawo lofunikira pazida zamakono zowonera, pulasitiki ndi zitsulo kukhala zosankha ziwiri zazikulu zakuthupi. Kusiyanitsa pakati pa mitundu iwiriyi kumawonekera pamiyeso yosiyanasiyana, kuphatikizapo katundu wakuthupi, kulimba, kulemera, mtengo, ndi kutentha kwa kutentha. Pepalali lidzapereka kusanthula mozama kwa kusiyana kumeneku pamene ikuwunika ubwino ndi kuipa kwa mtundu uliwonse mogwirizana ndi zochitika zothandiza.
**Zakuthupi ndi Kukhalitsa **
Magalasi apulasitiki
Magalasi apulasitiki amapangidwa makamaka kuchokera ku mapulasitiki aukadaulo apamwamba kwambiri monga ABS (acrylonitrile butadiene styrene copolymer) kapena PC (polycarbonate). Zidazi zimagwiritsidwa ntchito kwambiri pamagetsi ogula chifukwa cha mawonekedwe awo abwino komanso kuthekera kwachuma. Mwachindunji, ABS imawonetsa kukana kwamphamvu komanso kosavuta kukonza, pomwe PC imadziwika chifukwa chowonekera bwino komanso kukana kutentha. Ngakhale zabwino izi, magalasi apulasitiki nthawi zambiri amawonetsa kulimba pang'ono poyerekeza ndi njira zina zachitsulo. Mwachitsanzo, pakugwiritsa ntchito nthawi zonse, pamwamba pa magalasi apulasitiki amatha kukala, makamaka akakumana ndi zinthu zolimba popanda njira zodzitetezera. Kuphatikiza apo, kuyang'ana kwanthawi yayitali kutentha kwambiri kapena cheza cha ultraviolet kungayambitse kukalamba kapena kupindika, zomwe zitha kusokoneza magwiridwe antchito onse a lens.
Magalasi a Metal
Mosiyana ndi izi, magalasi achitsulo nthawi zambiri amapangidwa kuchokera kuzitsulo zamphamvu kwambiri monga aluminium kapena magnesium. Zidazi zili ndi zida zabwino zamakina, kuphatikiza kulimba kwambiri, kukana kuvala, komanso kukana kukhudzidwa, zomwe zimakulitsa kulimba kwawo motsutsana ndi kuvala ndi kutsika pakagwiritsidwe ntchito tsiku lililonse. Aluminiyamu alloy, mwachitsanzo, yakhala chisankho chokondedwa pazida zambiri zapamwamba chifukwa chakukwanira kwake kokwanira komanso kusinthika. Komano, ma aloyi a Magnesium amalemekezedwa chifukwa chopepuka komanso kulimba kwawo, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira kuchepetsedwa kulemera komanso kukhazikika kwamapangidwe. Komabe, kuchulukirachulukira kwazinthu zachitsulo kumapangitsa kuti kulemera kwake kuchuluke, ndipo njira zopangira zovuta zimakweza kwambiri mtengo wopangira poyerekeza ndi magalasi apulasitiki.
**Kulemera ndi Mtengo**
Magalasi apulasitiki
Chifukwa chogwiritsa ntchito zinthu zopepuka, magalasi apulasitiki amapambana pakuwongolera kulemera. Khalidweli ndi lothandiza kwambiri pazida zonyamulika, chifukwa kulemera kopepuka kumakulitsa luso la wogwiritsa ntchito komanso kumachepetsa kutopa komwe kumachitika chifukwa chogwiritsa ntchito nthawi yayitali. Kuphatikiza apo, kutsika mtengo kwa magalasi apulasitiki kumapangitsa kuti pakhale mitengo yopikisana, zomwe zimawapangitsa kukhala oyenera kwa ogula omwe amasamala bajeti. Makamera ambiri olowera ndi mafoni am'manja, mwachitsanzo, amaphatikizira magalasi apulasitiki kuti achepetse ndalama zopangira ndikusunga phindu lamitengo.
Magalasi a Metal
Ma lens achitsulo, mosiyana, amawonetsa kulemera kwakukulu chifukwa chogwiritsa ntchito zinthu zolemera kwambiri. Ngakhale izi zitha kubweretsa zovuta kwa ogwiritsa ntchito ena, zimakhala zovuta kwambiri pazokonda akatswiri. Pazida zojambulira ndi zida zamakampani, ma lens achitsulo amapereka kukhazikika kokhazikika komanso magwiridwe antchito odalirika pamikhalidwe yovuta. Komabe, kukwera mtengo kwa magalasi achitsulo kumakhalabe kofunikira. Kuchokera pakugula zinthu zopangira mpaka kukanika kolondola, sitepe iliyonse imafuna zinthu zambiri, zomwe zimapangitsa kuti mitengo ikhale yokwera. Chifukwa chake, magalasi achitsulo amapezeka kwambiri m'misika yapakati mpaka yotsika kwambiri, zomwe zimapatsa ogwiritsa ntchito omwe amaika patsogolo ubwino ndi magwiridwe antchito.
**Magwiridwe a Thermal**
Magalasi apulasitiki
Cholepheretsa chodziwika bwino cha magalasi apulasitiki ndi kutsika kwawo kwamafuta. M'madera otentha kwambiri, zipangizo zapulasitiki zimavutika kuti zithetse kutentha bwino, zomwe zimapangitsa kuti pakhale kutentha kwakukulu komwe kungasokoneze kukhazikika ndi moyo wa zipangizo. Mwachitsanzo, kujambula mavidiyo kwanthawi yayitali kapena ntchito zamakompyuta zitha kusokoneza magwiridwe antchito amagetsi amkati kapena kuwonongeka chifukwa cha kutentha kwambiri. Kuti achepetse vutoli, opanga nthawi zambiri amaphatikiza zida zowonjezera zowonjezera kutentha pakupanga magalasi apulasitiki, ngakhale izi zimawonjezera zovuta komanso mtengo.
Magalasi a Metal
Ma lens achitsulo amawonetsa kutenthedwa kwapamwamba chifukwa chachilengedwe chapamwamba chamafuta azinthu zachitsulo. Mwachitsanzo, aluminiyamu aloyi amaonetsa matenthedwe matenthedwe pafupifupi 200 W/(m·K), kupitirira patali zinthu zapulasitiki zambiri (nthawi zambiri zosakwana 0.5 W/(m·K)). Kuthekera kwa kutentha kumeneku kumapangitsa kuti magalasi achitsulo akhale oyenerera kugwiritsa ntchito bwino kwambiri, monga makamera akatswiri, makina owonera, ndi zida zowonera zamankhwala. Ngakhale pamikhalidwe yovuta kwambiri, magalasi achitsulo amakhalabe okhazikika, motero amakulitsa moyo wautumiki wa zida.
**Chidule**
Pomaliza, magalasi apulasitiki ndi zitsulo ali ndi zabwino komanso zoperewera. Magalasi apulasitiki, omwe amadziwika kuti ndi opepuka komanso otsika mtengo, ndi oyenerera bwino pamagetsi ogula ndi zida zam'manja. Ma lens achitsulo, osiyanitsidwa ndi kulimba kwawo kwapadera komanso magwiridwe antchito amafuta, amakhala ngati njira yomwe amakonda pamadomeni akatswiri komanso misika yoyambira. Ogwiritsa ntchito amatha kusankha mtundu wa lens woyenera kwambiri kutengera zomwe mukufuna kugwiritsa ntchito komanso zovuta za bajeti kuti akwaniritse ntchito yabwino.
