一,Kedu ihe bụ lensị UV
Lensi UV, nke a makwaara dị ka lensi ultraviolet, bụ lensi anya nke e mere kpọmkwem iji zipu ma lekwasị anya na ìhè ultraviolet (UV). Ìhè UV, nke nwere ogologo ebili mmiri na-ada n'etiti 10 nm ruo 400 nm, karịrị oke ìhè a na-ahụ anya na spectrum electromagnetic.
A na-ejikarị anya UV eme ihe n'ihe gbasara onyonyo na nyocha na oke UV, dịka fluorescence microscopy, UV spectroscopy, lithography, na nkwukọrịta UV. Anya ndị a nwere ike izipu ìhè UV na obere mmịpụta na mgbasa, na-enye ohere maka onyonyo ma ọ bụ nyocha doro anya na nke ziri ezi nke ihe nlele ma ọ bụ ihe.
Nhazi na imepụta lenzi UV dị iche na nke lenzi ìhè a na-ahụ anya n'ihi ihe pụrụ iche nke ìhè UV. Ihe eji eme lenzi UV na-agụnyekarị silica fused, calcium fluoride (CaF2), na magnesium fluoride (MgF2). Ihe ndị a nwere nnukwu nnyefe UV na obere nnabata UV, nke na-eme ka ha dabara adaba maka ojiji UV. Na mgbakwunye, imewe lenzi kwesịrị ịtụle mkpuchi anya pụrụ iche iji mee ka nnyefe UV dịkwuo mma.
Anya UV na-abịa n'ụdị dị iche iche, gụnyere anya plano-convex, biconvex, convex-concave, na lensis meniscus. Nhọrọ nke ụdị lenses na nkọwapụta ya dabere na ihe achọrọ maka ngwa ahụ, dịka ogologo lenses achọrọ, ebe a na-ahụ ya, na ịdị mma onyonyo.
二,Tnjirimara na ojiji nke lenses UV
Enwere ụfọdụ atụmatụ na ojiji nke lensị UV:
Fnri:
Mgbasa UV: E mere enyo UV ka ha na-ebufe ìhè ultraviolet n'enweghị mmetụta na mgbasa. Ha nwere ike ịgafe oke ogologo UV, nke na-adịkarị n'agbata 200 nm ruo 400 nm.
Obere Mmebi: Emebere anya UV iji belata mgbanwe chromatic na ụdị mgbanwe anya ndị ọzọ iji hụ na e guzobere onyonyo na nyocha ziri ezi na oke UV.
Nhọrọ Ihe:A na-eji ihe ndị nwere oke nnyefe UV na obere mmịpụta UV eme ihe anya UV, dị ka fused silica, calcium fluoride (CaF2), na magnesium fluoride (MgF2).
Mkpuchi Pụrụ Iche: Anya UV na-achọkarị mkpuchi anya pụrụ iche iji melite nnyefe UV, belata ntụgharị uche, ma chebe anya ahụ pụọ na ihe ndị metụtara gburugburu ebe obibi.
Ngwa:
Nyocha nke Fluorescence:A na-ejikarị anya UV eme ihe na nyocha fluorescence iji kpalie ma nakọta ihe mgbaàmà fluorescence nke fluorescence na-ewepụta. Isi iyi ọkụ UV na-enyere aka na mkpali nke nyocha fluorescence kpọmkwem, na-enye ohere maka onyonyo zuru ezu nke ihe nlele bayọlọji.
Nyocha UV:A na-eji anya UV eme ihe n'ihe gbasara spectroscopy nke chọrọ nyocha nke nnabata UV, mwepụta, ma ọ bụ spectra nnyefe. Nke a bara uru n'ọtụtụ ngalaba nyocha sayensị, gụnyere kemistri, nlekota gburugburu ebe obibi, na sayensị ihe.
Litography:Anya UV bụ ihe dị mkpa na fotolithography, usoro eji eme ihe na semiconductor iji bipụta ụkpụrụ dị mgbagwoju anya na wafer silicon. Ikpughe ìhè UV site na lenzi na-enyere aka ibufe ụkpụrụ zuru ezu na ihe photoresist.
Nkwukọrịta UV:A na-eji anya UV eme ihe na sistemụ nkwukọrịta UV maka nnyefe data ikuku dị mkpụmkpụ. Ìhè UV na-eme ka nkwukọrịta anya dị n'ahịrị, nke a na-ejikarị eme ihe n'èzí, ebe ihe mgbochi dịka osisi na ụlọ enweghị nnyonye anya dị nta ma e jiri ya tụnyere ìhè a na-ahụ anya.
Nyocha Akwụkwọ na Nnyocha Akwụkwọ:A na-eji anya UV eme ihe n'ule nyocha na nyocha akwụkwọ iji kpughee ozi zoro ezo ma ọ bụ nke agbanwere agbanwe. Ìhè UV nwere ike ikpughe ihe ndị na-emeghachi omume na UV, ikpughe atụmatụ nchekwa, ma ọ bụ chọpụta akwụkwọ ndị e ji aghụghọ mee.
Nnwale UV:A na-eji anya UV eme ihe na ngwaọrụ UV iji kpochapụ mmiri, ikuku, ma ọ bụ elu. Ìhè UV nke na-esi na anya ahụ apụta na-arụ ọrụ nke ọma n'ime ka DNA nke obere ihe ndị dị ndụ ghara ịdị irè, na-eme ka ọ bụrụ ihe a na-ahọrọkarị maka ọgwụgwọ mmiri na iji ọgwụ nje mee ihe.
N'ozuzu, a na-eji anya UV eme ihe n'ọtụtụ ebe sayensị, ụlọ ọrụ mmepụta ihe, na teknụzụ ebe onyonyo UV ziri ezi, nyocha spectral, ma ọ bụ njikwa ọkụ UV dị oke mkpa.
