Ma lens a Cylindrical

Ma lens a cylindrical ali ndi ma radii osiyanasiyana mu nkhwangwa za x ndi y, amafanana ndi ma lens ozungulira chifukwa amagwiritsa ntchito malo opindika kuti asinthe kapena kusiyanitsa kuwala, koma ma lens a silinda ali ndi mphamvu ya kuwala mugawo limodzi lokha ndipo sangakhudze kuwala kwa perpendicular. dimension.Malensi a Cylinder ali ndi silinda imodzi yokha yomwe imapangitsa kuwala kobwerako kuyang'ana mu mulingo umodzi wokha, mwachitsanzo, kukhala pamzere m'malo mwa mfundo, kapena kusintha chiyerekezo cha chithunzi mu mulingo umodzi wokha.Ma lens ozungulira amakhala ndi masikelo, ozungulira, kapena amakona anayi, monga ma lens ozungulira amapezekanso ndi utali wokhazikika kapena woyipa.Ma lens a cylindrical amagwiritsidwa ntchito kwambiri kusintha kukula kwa chithunzi, kapena kukonza astigmatism pamakina ojambulira, komanso pamagwiritsidwe osiyanasiyana a laser kuphatikiza mizati yozungulira yozungulira kuchokera ku laser diode, kuyang'ana mtengo wopatukana pagulu lojambulira mzere, ndikupanga pepala lowala. kwa makina oyezera, kapena kuwonetsera mzere wa laser pamwamba.Ma lens a cylindrical amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza kuyatsa kwa detector, bar code scanning, spectroscopy, kuyatsa kwa holographic, kukonza zidziwitso ndiukadaulo wamakompyuta.

Magalasi owoneka bwino a cylindrical ali ndi malo amodzi athyathyathya ndi malo amodzi opingasa, ndi abwino kwa mapulogalamu omwe amafunikira kukula mu gawo limodzi.Ngakhale magalasi ozungulira amachita mofanana miyeso iwiri pa cheza cha zochitika, ma lens ozungulira amachita chimodzimodzi koma mugawo limodzi lokha.Ntchito yodziwika bwino ingakhale kugwiritsa ntchito ma lens a cylindrical kuti apereke mawonekedwe a anamorphic a mtengo.Kugwiritsa ntchito kwina ndiko kugwiritsa ntchito mandala amodzi okhawo omwe ali ndi mawonekedwe ozungulira kuti ayang'ane panjira yolowera pagulu lazowonera;Magalasi abwino a cylindrical amatha kugwiritsidwa ntchito kuti agwirizane ndikuzungulira kutulutsa kwa laser diode.Kuchepetsa kuyambika kwa mizere yozungulira, kuwala kozungulira kuyenera kuchitika pamalo okhotakhota pamene akuloza pamzere, ndipo kuwala kochokera kugwero la mzere kuyenera kuchitika pamtunda wa pulani pamene kuwombana.

Ma lens a negative cylindrical ali ndi malo amodzi athyathyathya ndi malo amodzi opindika, ali ndi utali wolunjika ndipo amakhala ngati magalasi ozungulira a plano-concave, kupatula pa mulingo umodzi wokha.Ma lens awa amagwiritsidwa ntchito pamapangidwe omwe amafunikira mawonekedwe amtundu umodzi wa gwero la kuwala.Ntchito yodziwika bwino ingakhale kugwiritsa ntchito mandala amodzi osawoneka bwino kuti asinthe laser yolumikizana kukhala jenereta ya mzere.Ma lens awiri a cylindrical atha kugwiritsidwa ntchito popanga zithunzi.Kuti muchepetse kuyambika kwa kutembenuka, malo opindika a lens ayenera kuyang'anizana ndi komwe akuchokera akagwiritsidwa ntchito kupatutsa mtengo.
Paralight Optics imapereka ma lens a cylindrical opangidwa ndi N-BK7 (CDGM H-K9L), silika wosakanikirana ndi UV, kapena CaF2, onse omwe amapezeka osakutidwa kapena zokutira zotchingira.Timaperekanso mitundu yozungulira yamagalasi athu ozungulira, ma lens a ndodo, ndi ma cylindrical achromatic doublet pazogwiritsa ntchito zomwe zimafuna kusinthasintha pang'ono.
