I-Precision Plano-Concave kanye ne-Double Concave Lens
Incazelo Yomkhiqizo
Ilensi ye-plano-concave inendawo eyodwa eyisicaba kanye nendawo eyodwa egobile yangaphakathi, okwenza imisebe yokukhanya ihlukane.Lawa ma-lens avame ukusetshenziselwa ukulungisa umbono wabantu ababona eduze (i-myopic), njengoba enza ukuba ukukhanya okungena ehlweni kuphambukise ngaphambi kokuba kufinyelele kuyi-lens, ngaleyo ndlela kuvumele ukugxila ku-retina ngendlela efanele.
Amalensi e-Plano-concave nawo asetshenziswa ezinhlelweni zokubona ezifana nezibonakude, ama-microscopes, nezinye izinsimbi ezihlukahlukene njengezinjongo zokwakha izithombe namalensi ahlanganisayo.Zibuye zisetshenziswe kuma-expander we-laser beam kanye nezinhlelo zokusebenza zokubunjwa kwe-beam.
Amalensi ama-concave kabili afana namalensi e-plano-concave kodwa anezindawo zombili ezigobile ngaphakathi, okuholela emisebeni yokukhanya ephambukayo.Asetshenziselwa ukusabalalisa nokugxila ekukhanyeni ezinhlelweni ezifana nezinsimbi ezibonakalayo, amasistimu wokuthwebula izithombe, namasistimu okukhanyisa.Zibuye zisetshenziswe ngokujwayelekile kuma-expander we-beam kanye nezinhlelo zokusebenza zokubunjwa kwe-beam.
Ukunemba kwe-plano-concave kanye namalensi a-Double-concave ayizingxenye ezibalulekile ezisetshenziswa kumadivayisi ahlukahlukene okubona.Lawa ma-lens aziwa ngokunemba kwawo okuphezulu, ukunemba kanye nekhwalithi.Asetshenziswa ezinhlelweni ezifana ne-microscopy, ubuchwepheshe be-laser kanye nemishini yezokwelapha.Lawa ma-lens aklanyelwe ukusiza ukuthuthukisa ukucaca kwesithombe, ukucaca nokugxila.
Amalensi e-plano-concave ane-precision anendawo eyisicaba ngakolunye uhlangothi kanye ne-concave kolunye.Lo mklamo usiza ekuhlukaniseni ukukhanya futhi usetshenziselwa ukulungisa noma ukulinganisa amalensi amahle kumasistimu okukhanya.Avame ukusetshenziswa ngokuhlanganiswa namanye amalensi amahle ohlelweni lokuthwebula izithombe ukuze kuncishiswe ukuphambana okuphelele kwesistimu.
Amalensi e-Biconcave, ngakolunye uhlangothi, ane-concave ezinhlangothini zombili futhi aziwa nangokuthi ama-biconcave lens.Asetshenziswa ngokuyinhloko ezinhlelweni zokuthwebula izithombe ukuze akhulise ukukhanya futhi anciphise ukukhuliswa okuphelele kwesistimu.Zibuye zisetshenziswe njengezandisi ze-beam noma izinciphisi ezinhlelweni ze-optical lapho kudingeka khona ama-diameter ancishisiwe.
Lawa ma-lens akhiqizwa kusetshenziswa izinto ezahlukahlukene ezifana nengilazi, ipulasitiki ne-quartz.Amalensi engilazi ayizinhlobo ezivame ukusetshenziswa ngokunemba zeplano-concave kanye ne-bi-concave lens.Aziwa ngama-optics ekhwalithi ephezulu aqinisekisa ukucaca okuhle kwesithombe.
Njengamanje, kunabakhiqizi abaningi abahlukene abakhiqiza i-Precision Plano-Concave yekhwalithi ephezulu kanye namalensi e-Double Concave.E-Suzhou Jiujon Optics, i-Precision Plano-Concave kanye namalensi e-Double Concave enziwe ngengilazi yekhwalithi ephezulu, enezici ezinhle kakhulu zokubona.Amalensi aphansi ngokunembile ukuze kuqinisekiswe ukuthi ahlangabezana nezindinganiso eziqinile zekhwalithi, futhi atholakala ngebanga losayizi ukuze ahlangabezane nezidingo zezinhlelo zokusebenza ezahlukene.
I-precision plano-concave kanye ne-bi-concave lens ayizici ezibalulekile ezisetshenziswa ezinhlelweni ezihlukahlukene, okuhlanganisa i-microscopy, ubuchwepheshe be-laser, kanye nemishini yezokwelapha.Lawa ma-lens adlala indima ebalulekile ekuthuthukiseni ukucaca kwesithombe, ukucaca nokugxila futhi akhiqizwa kusetshenziswa izinto ezahlukene ezifana nengilazi ne-quartz.Zaziwa ngokunemba kwazo okuphezulu, ukunemba, kanye nekhwalithi, zilungele izinhlelo zokusebenza ezidinga ama-optics asebenza kahle kakhulu.
