I-Precision Plano-Concave kunye ne-Double Concave Lens
Ingcaciso yeMveliso
Ilensi yeplano-concave inomphezulu omnye othe tyaba kunye nomnye ongaphakathi ogobileyo, nto leyo ebangela ukuba imitha yokukhanya yahlukane.Ezi lens zisoloko zisetyenziselwa ukulungisa indlela yokubona abantu ababona kufutshane ( myopic ), njengoko zibangela ukuba ukukhanya okungena esweni kuphaluke ngaphambi kokuba kufikelele kwilensi, ngaloo ndlela kuyivumela ukuba igxile kwiretina ngokufanelekileyo.
Iilensi zePlano-concave zikwasetyenziswa kwiinkqubo zamehlo ezinje ngeteleskopu, iimicroscopes, kunye nezinye izixhobo ezahlukeneyo njengeenjongo zokwenza umfanekiso kunye neelensi ezidibanisayo.Zikwasetyenziswa kwizandisi ze-laser beam kunye nezicelo zokubumba umqadi.
Iilensi eziphindwe kabini eziconcave ziyafana neelensi zeplano-concave kodwa zinemigangatho yomibini egobileyo ngaphakathi, ikhokelela kwimitha yokukhanya eyahlukanayo.Zisetyenziselwa ukusabalalisa kunye nokugxininisa ukukhanya kwizicelo ezifana nezixhobo ze-optical, iinkqubo zokucinga, kunye neenkqubo zokukhanyisa.Zikwasetyenziswa ngokuqhelekileyo kwizandisi ze-beam kunye nezicelo zokubunjwa kwe-beam.
Ukuchaneka kweplano-concave kunye ne-Double-concave lens zizinto ezibalulekileyo ezisetyenziswa kwizixhobo ezahlukeneyo zamehlo.Ezi lens ziyaziwa ngokuchaneka kwazo okuphezulu, ukuchaneka kunye nomgangatho.Zisetyenziswa kwizicelo ezifana ne-microscopy, iteknoloji yelaser kunye nezixhobo zonyango.Ezi lens zenzelwe ukunceda ukuphucula ukucaca komfanekiso, ubukhali kunye nokugxila.
Iilensi zeplano-concave ezichanekileyo zinomphezulu osicaba kwelinye icala kunye nomphezulu we-concave kwelinye.Olu yilo lunceda ukuhlukana kokukhanya kwaye lusetyenziselwa ukulungisa okanye ukulinganisa iilensi ezintle kwiinkqubo zamehlo.Zihlala zisetyenziswa ngokudibeneyo kunye nezinye iilensi ezilungileyo kwinkqubo yokucinga ukunciphisa ukuphambuka okupheleleyo kwenkqubo.
Iilensi zeBiconcave, kwelinye icala, ziconcave kumacala omabini kwaye zikwabizwa ngokuba ziilensi zebiconcave.Zisetyenziswa ngokuyintloko kwiinkqubo zokucinga ukukhulisa ukukhanya kunye nokunciphisa ukukhuliswa ngokubanzi kwenkqubo.Zikwasetyenziswa njengezandisi ze-beam okanye abanciphisi kwiinkqubo ze-optical apho kufuneka i-diameter encitshisiweyo.
Ezi lens zenziwa kusetyenziswa izinto ezahlukeneyo ezifana neglasi, iplastiki kunye nequartz.Iilensi zeglasi zezona ntlobo zixhaphakileyo ezichanekileyo zeplano-concave kunye nebi-concave lens.Baziwa ngomgangatho ophezulu we-optics oqinisekisa ukucaca komfanekiso.
Okwangoku, kukho abavelisi abaninzi abahlukeneyo abavelisa umgangatho ophezulu we-Precision Plano-Concave kunye ne-Double Concave Lenses.E-Suzhou Jiujon Optics, i-Precision Plano-Concave kunye ne-Double Concave lens zenziwe ngeglasi ekumgangatho ophezulu, eneempawu ezibalaseleyo zokukhanya.Iilensi zibekwe ngokuchanekileyo ukuqinisekisa ukuba ziyahlangabezana nemigangatho yomgangatho ongqongqo, kwaye ziyafumaneka kuluhlu lobungakanani ukuhlangabezana neemfuno zezicelo ezahlukeneyo.
I-precision plano-concave kunye ne-bi-concave lens zizinto ezibalulekileyo ezisetyenziswa kwizicelo ezahlukeneyo, kubandakanywa i-microscopy, iteknoloji ye-laser, kunye nezixhobo zonyango.Ezi lens zidlala indima ebalulekileyo ekuphuculeni ukucaca komfanekiso, ukucaca kunye nokugxila kwaye zenziwe kusetyenziswa izinto ezahlukeneyo ezifana neglasi kunye ne-quartz.Ezaziwa ngokuchaneka kwazo okuphezulu, ukuchaneka, kunye nomgangatho, zifanelekile kwizicelo ezifuna ii-optics ezisebenza kakhulu.
