I-Pleno-Concave kunye ne-concave ezimbini ze-cocave
Ingcaciso yeMveliso
I-lens ye-plano-cocave inomphezulu omnye weflethi kunye nomgangatho omnye ogobileyo, obangela imitha yokukhanya. Ezi lens zihlala zisetyenziselwa ukulungisa umbono wabantu obotshwe (i-myopic), njengoko oko besenza ukukhanya kungene kwilensi, ngaloo ndlela kuvumela ukuba kugxilwe kwi-retina ngokufanelekileyo.
Iilebhu zePlano-Concave zisetyenziswa kwiinkqubo ze-fashscopes ezifana neeteleskopu, i-microssopus, kunye nezinye izixhobo ezahlukeneyo njengeenjongo zokwenza imifanekiso kunye neelensi zokwenza imifanekiso. Zikwasetyenziswa nakwi-laser ye-laser yenyosi kunye ne-Beam yokuguqula izicelo.
Iilensi ezimbini ze-cocave ziyafana kwi-lenses ye-plano-concave kodwa zombini zigcwele ngaphakathi, zikhokelela ekuphambukiseni imitha yokukhanya. Zisetyenziselwa ukusasaza nokugxila kwizicelo ezinjengezinto zamehlo, zokucinga, kunye neenkqubo zokukhanyisa. Ziqhelekile ezisetyenziselwa ukwanda kwe-beam kunye nokusebenza kwe-beam.
I-Plano-Concave kunye neelensi ezimbini ze-cocave zizinto ezibalulekileyo ezisetyenziswa kwizixhobo ezahlukeneyo zamehlo. Ezi lensi zaziwa ngokubaluleka kwabo, ukuchaneka kunye nomgangatho. Zisetyenziswa kwizicelo ezinjenge-microscopy, itekhnoloji ye-laser kunye nezixhobo zonyango. Ezi lense zenzelwe ukunceda ukuphucula ukucaciswa komfanekiso, ubukhali kunye nokugxila.
Ukuchaneka kwePlano-Concave Lenses anendawo ethe tyaba kwelinye icala kunye nomphezulu we-concave kwelinye. Olu luyilo lunceda ukukhanya kwaye isetyenziselwa ukulungisa okanye ilungelelanise iilensi ezintle kwiinkqubo ze-optical. Zihlala zisetyenziswa kunye nezinye iilensi ezifanelekileyo kwinkqubo yokucinga yokunciphisa i-acketions iyonke yenkqubo.
I-Biconseil Lenses, kwelinye icala, i-cocauve kumacala omabini kwaye ikwabizwa ngokuba ziilensi zeBiconCave. Ngokuyintloko basetyenziswa ekufundeni iinkqubo zokukhulisa ukukhanya kwaye zinciphise ukukhulelwa kwenkqubo. Zikwasetyenziswa njengama-beam abavuyisi okanye abacimisi kwiinkqubo ze-optical apho kufuneka iidayala zeBeam.
Ezi lens zenziwa zisebenzisa izixhobo ezahlukeneyo ezinje ngeglasi, iplastiki kunye ne-quartz. Iilebhu zeglasi zezona ntlobo zisetyenziswa ziqhelekileyo zePlano-concave kunye neentlobo zeles. Bayaziwa ukuba bazibone kakuhle ekuqinisekiseni ukucaciswa komfanekiso okufuthi.
Okwangoku, baninzi abavelisi abahlukeneyo bevelisa i-plano-cocave kunye neelensi ezimbini ze-cocave. Kwi-suzhou jiujon optics, i-procape echanekileyo kunye neelebhu ze-concave ezimbini zenziwe kwiglasi ekumgangatho ophezulu, eneempawu ezibalaseleyo. I-lenseds icocekile ngokuchanekileyo ukuqinisekisa ukuba bayayifezekisa imigangatho esemgangathweni, kwaye bayafumaneka kuluhlu lwe-SEIRT ukuhlangabezana neemfuno zezicelo ezahlukeneyo.
I-Plano-Concave kunye neelensi ze-BI-concave zezinto ezibalulekileyo ezisetyenziswa kwizicelo ezahlukeneyo, kubandakanya nemicrossiscopy, itekhnoloji ye-laser, kunye nezixhobo zonyango. Ezi lens zidlala indima ebalulekileyo ekuphuculeni ukucaciswa kwemifanekiso, ukucaciswa kunye nokugxila kwaye kwenziwa kusetyenziswa izixhobo ezahlukeneyo ezinje ngeglasi kunye ne-quartz. Yaziwa ngokubaluleka kwabo, ukuchaneka, kunye nomgangatho, kufanelekile ukuba izicelo zifuna ii-appiks zokusebenza eziphezulu.
