Precision Plano-Concave iyo Lenses Concave Double
Sharaxaada Alaabta
Muraayada plano-concave lens-ku waxa uu leeyahay hal oog oo siman iyo mid gudaha ah oo qaloocan, kaas oo keena falaadhaha iftiinka in ay kala duwanaadaan. Muraayadahan ayaa inta badan loo adeegsadaa in lagu saxo aragga dadka u dhow aragga (myopic), maadaama ay sababaan in iftiinka isha soo galaya uu kala duwanaado ka hor inta uusan gaarin muraayadda, taasoo u sahlaysa inay si habboon diiradda u saarto xuubka isha.
Lenses-concave lenses sidoo kale waxaa loo isticmaalaa hababka indhaha sida telescopes, mikroskoobyada, iyo qalab kale oo kala duwan sida ujeeddooyinka samaynta image iyo collimating lenses. Waxa kale oo loo isticmaalaa balaadhinta laydhka laysarka iyo codsiyada qaabaynta iftiinka.
Muraayadaha labajibbaaran ee concave waxay la mid yihiin lenses-concave lenses laakiin waxay leeyihiin labada dusha sare ee gudaha u qalloocan, taasoo keentay inay kala duwanaadaan fallaadhaha iftiinka. Waxaa loo adeegsadaa in lagu faafiyo oo diiradda la saaro iftiinka codsiyada sida aaladaha indhaha, nidaamyada sawirka, iyo nidaamyada iftiinka. Waxa kale oo si caadi ah loo isticmaalaa balaadhinta alwaaxda iyo codsiyada qaabaynta qoryo.
Qoryaha saxda ah ee loo yaqaan 'plano-concave' iyo lenses Double-concave waa qaybo muhiim ah oo loo isticmaalo aaladaha indhaha ee kala duwan. Muraayadahan waxaa lagu yaqaanaa saxnaanta sare, saxnaanta iyo tayada. Waxaa loo adeegsadaa codsiyada sida mikroskoobyada, tignoolajiyada laysarka iyo qalabka caafimaadka. Muraayadahan waxaa loogu talagalay inay caawiyaan hagaajinta muuqaalka muuqaalka, fiiqan iyo diiradda.
Lenses plano-concave oo sax ah waxay leeyihiin oog siman oo dhinac ah iyo dusha kale oo daboolan. Naqshadani waxay caawisaa kala-duwanaanta iftiinka waxaana loo isticmaalaa in lagu saxo ama la isku dheellitiro muraayadaha togan ee hababka indhaha. Inta badan waxaa loo isticmaalaa in lagu daro muraayadaha kale ee togan ee nidaamka sawir-qaadista si loo yareeyo khalkhalka guud ee nidaamka.
Lenses Biconcave, dhinaca kale, waa isku dhejisan labada dhinac waxaana sidoo kale loo yaqaannaa muraayadaha biconcave. Waxay ugu horreyn loo adeegsadaa hababka sawir-qaadista si loo kordhiyo iftiinka oo loo yareeyo guud ahaan weyneynta nidaamka. Waxa kale oo loo isticmaalaa sida balaadhinta alwaaxda ama hoos-u-dhiyayaasha nidaamyada indhaha ee la dhimay dhexroorka iftiinka loo baahan yahay.
Muraayadahan waxaa lagu soo saaraa agabyo kala duwan sida dhalo, caag iyo quartz. Muraayadaha muraayadaha ayaa ah kuwa ugu badan ee la isticmaalo ee saxda ah ee plano-concave iyo noocyada muraayadaha laba-kooxeed. Waxay caan ku yihiin indho-indheyn tayo sare leh oo hubiya caddaynta sawirka ugu wanaagsan.
Waqtigan xaadirka ah, waxaa jira soosaarayaal badan oo kala duwan oo soo saara tayada sare ee Precision Plano-Concave iyo Double Concave lenses. Suzhou Jiujon Optics, Precision Plano-Concave iyo Double Concave lenses ayaa laga sameeyay muraayad tayo sare leh, kaas oo leh sifooyin muuqaal ah oo aad u wanaagsan. Muraayadaha ayaa si sax ah loo dejiyay si loo hubiyo inay la kulmaan heerarka tayada adag, waxaana lagu heli karaa cabbirro kala duwan si ay u daboolaan baahiyaha codsiyada kala duwan.
Qoryaha saxda ah ee loo yaqaan 'plano-concave' iyo muraayadaha laba-kooxeed ayaa ah qaybo muhiim ah oo loo isticmaalo codsiyo kala duwan, oo ay ku jiraan microscopy, tignoolajiyada laysarka, iyo qalabka caafimaadka. Muraayadahani waxay door muhiim ah ka ciyaaraan hagaajinta muuqaalka muuqaalka, caddaynta iyo diiradda waxaana la soo saaray iyadoo la adeegsanayo qalabyo kala duwan sida quraarad iyo quartz. Loo yaqaan saxnaantooda sare, saxnaanta, iyo tayada, waxay ku fiican yihiin codsiyada u baahan indho-indheynta waxqabadka sare.
