Mawu Oyamba

Ma lens a Cylindrical ndi mtundu wapadera wa mandala a silinda, ndipo amapukutidwa kwambiri pozungulira komanso pansi mbali zonse ziwiri.Ma lens ozungulira amatha kugwira ntchito mofanana ndi mandala a silinda wamba, ndipo amatha kugwiritsidwa ntchito popanga nsonga ndi kuyang'ana kuwala kophatikizana kukhala mzere.Ma cylindrical lens ndi ma lens owoneka omwe amapindika mbali imodzi yokha.Chifukwa chake, amangoyang'ana kapena kufooketsa kuwala kumbali imodzi, mwachitsanzo molunjika koma osati molunjika.Ponena za magalasi wamba, kuyang'ana kwawo kapena kufooketsa kwawo kumatha kuzindikirika ndi kutalika kwake kapena kusinthika kwake, mphamvu ya dioptric.Ma lens a cylindrical amatha kugwiritsidwa ntchito kuti apeze mawonekedwe amtundu wa elliptical.Izi zitha kufunidwa, mwachitsanzo, pakuyatsa kuwala kudzera polowera pakhomo la monochromator kapena chopindika cha acousto-optic, kapena pakuwongolera kuwala kwapampu kwa laser slab.Pali ma axis collimators othamanga a ma diode, omwe amakhala ma lens ozungulira - nthawi zambiri amakhala ndi mawonekedwe a aspheric.Ma cylindrical lens amayambitsa astigmatism ya laser mtengo: kusagwirizana kwa malo olunjika mbali zonse ziwiri.Kumbali ina, amatha kugwiritsidwanso ntchito kubweza astigmatism ya mtengo kapena mawonekedwe a kuwala.Mwachitsanzo, angafunike kuti agwirizane ndi kutulutsa kwa laser diode kuti munthu apeze mtengo wozungulira wopanda astigmatic.Kufunika kwakukulu kwa lens ya cylindrical ndikutha kuyang'ana kuwala pamzere wopitilira osati malo okhazikika.Ubwinowu umapatsa ma lens a cylindrical maluso osiyanasiyana apadera, monga kupanga mzere wa laser.Zina mwazinthuzi sizingatheke ndi lens yozungulira.Ma lens a cylindrical.
