Ibisobanuro bitandukanye bya optique yikirahure ya convex yibanda kumurongo
Niki GukuzaIkirahure?
Barimo gukuza lensike ikozwe mubirahuri, nka Green ikirahure, Optical glass lens, K9, nibindi.ibikoresho byikirahure cya optique birahagaze neza kandi indangagaciro yumubiri iringaniye.Ntabwo izasaza byoroshye mugukoresha igihe kirekire kandi hejuru iroroshye kuvura, mugihe kimwe, magnifier ikirahure nacyo gishobora kuvurwa neza neza, gishobora kugera ku ngaruka nyinshi zisumba izindi, kwanduza cyane kugereranya, kurwanya infragre na ultraviolet, nibindi
Ikirahuri cyambere gikoreshwa mugukora lens nigituba kumadirishya isanzwe cyangwa amacupa ya vino.Imiterere isa na "ikamba", aho izina ryikirahure cyikirahure cyangwa ikirahure cya plaque.Muri icyo gihe, ikirahuri cyari kitaringaniye kandi kiba ifuro.Usibye ikirahuri cyikamba, hariho ubundi bwoko bwikirahure cya flint kirimo ibintu byinshi byo kuyobora.Ahagana mu 1790, Pierre Louis junnard, Umufaransa, yasanze kuvanga isosi y'ibirahure bishobora gukora ibirahuri bifite imiterere imwe.Mu 1884, Ernst Abbe na Otto Schott bo muri Zeiss bashinze Schott glaswerke Ag i Jena, mu Budage, maze bakora ibirahuri byinshi bya optique mu myaka mike.Muri byo, kuvumbura ikirahuri cya barium yikirahure hamwe nigipimo kinini cyo kugabanya ni kimwe mubikorwa byingenzi byagezweho nuruganda rwa Schott.
Ibigize ：
Ikirahuri cya optique kivanze na okiside ya silikoni-isukuye cyane, boron, sodium, potasiyumu, zinc, gurş, magnesium, calcium, barium, nibindi ukurikije formulaire yihariye, yashonga mubushyuhe bwinshi muri platine ibamba, ikavangwa neza hamwe na ultrasonic gukuraho ibituba;Noneho ukonje buhoro buhoro umwanya muremure kugirango wirinde guhangayika imbere mubirahuri.Ikirahure gikonje kigomba gupimwa nibikoresho bya optique kugirango harebwe niba ubuziranenge, gukorera mu mucyo, uburinganire, indangagaciro zidahwitse hamwe n’ibipimo bitandukanya byujuje ibisobanuro.Ikirahuri cyujuje ibyangombwa kirashyuha kandi gihimbwe kugirango kibe intanga ya optique.
Ibyiciro ：
Ikirahure gifite imiti isa na optique nayo ikwirakwizwa mumwanya wegeranye ku gishushanyo mbonera.Abettu y'uruganda rw'ibirahuri rwa Schott rufite umurongo ugororotse n'imirongo, igabanya abettu ahantu henshi kandi igashyira ibirahuri bya optique;Kurugero, ikirahuri cyikamba K5, K7 na K10 kiri muri zone K, naho ikirahure cya flint F2, F4 na F5 kiri muri zone F. Ibimenyetso mumazina yikirahure: F igereranya flint, K kuri plaque, B kuri boron, ba kuri barium , LA kuri lanthanum, n kubayobora-na P kuri fosifore.
Kubirahuri by'ikirahure, nini nini yo kureba, nini nini, kandi irashobora gutandukanya amakuru yikintu.Kwimukira hafi yikintu birashobora kongera inguni yo kureba, ariko bigarukira kubushobozi bwo kwibanda kumaso.Koresha ikirahure kinini kugirango kibe hafi yijisho, hanyuma ushire ikintu mubitekerezo byacyo kugirango ugire ishusho iboneye.
Igikorwa cyo gukuza ikirahure ni ugukuza inguni yo kureba.Mu mateka, bivugwa ko gukoresha ikirahure kinini byasabwe na grosstest, umwepiskopi w’Ubwongereza mu kinyejana cya 13.
Lens lens yikirahure irwanya izindi lens, ariko uburemere bwayo buraremereye, kandi indangantego yayo irarenze: firime isanzwe ni 1.523, firime ultra-thin irenga 1.72, kugeza kuri 2.0.
Ibikoresho nyamukuru byibirahuri ni ikirahure cya optique.Igipimo cyacyo cyo guhanagura kirenze icy'ibikoresho bya resin, bityo rero kurwego rumwe, ikirahuri cyoroshye kuruta lens.Ikirahuri cyikirahure gifite urumuri rwiza hamwe nubukanishi nubumashini, icyerekezo gihoraho kandi gihoraho kumubiri na chimique.Lens idafite ibara ryitwa optique yera yera (firime yera), naho firime yijimye muri firime yamabara yitwa croxay lens (film itukura).Lens ya Croxay irashobora gukurura imirasire ya ultraviolet kandi igatwara urumuri rukomeye.
Urupapuro rwikirahure rufite ibintu byiza bya optique, ntabwo byoroshye gushushanya, kandi bifite indangagaciro ndende.Kurwego rwo hejuru rwerekana ibimenyetso, byoroheje lens.Ariko ikirahure kiroroshye kandi ibikoresho biraremereye cyane.
Ni ubuhe buryo bukoreshwa mu gukuza ikirahure?
Lens
Ikirahure kinini ni lens ya convex ikoreshwa kugirango ikintu kigaragare kinini kuruta uko kiri.Ibi bikora iyo ikintu gishyizwe kure yuburebure bwibanze.
Ni ubuhe bunini bwo gukuza ikirahure nkeneye?
Muri rusange, 2-3X magnifier itanga umurima munini wo kureba nibyiza kubikorwa byo gusikana nko gusoma, mugihe umurima muto ujyanye no gukuza cyane byaba byiza ugenzuye utuntu duto.
