Ama-Cylindrical Lens

Amalensi angamacylindrical anerediya ehlukene kuma-ax kanye no-y, afana namalensi ayindilinga ngomqondo wokuthi asebenzisa izindawo ezigobile ukuze ahlangane noma ahlukanise ukukhanya, kodwa amalensi angamasilinda anamandla okubona endaweni eyodwa kuphela futhi ngeke athinte ukukhanya ku-perpendicular. ubukhulu.Ama-Cylinder Lens anobuso obuyisilinda obubodwa obubangela ukukhanya okungenayo ukuthi kugxilwe kuhlangothi olulodwa kuphela, okungukuthi, kube umugqa kunokuba kube iphuzu, noma aguqule ukubukeka kwesilinganiselo sesithombe ku-eksisi eyodwa kuphela.Amalensi angamacylindrical anezitayela eziyisikwele, eziyindilinga, noma eziyisiyingi, njengamalensi ayindilinga ayatholakala futhi anobude bokugxila obuphozithivu noma obunegethivu.Amalensi angama-cylindrical ajwayele ukusetshenziselwa ukulungisa usayizi wesithombe, noma ukulungisa i-astigmatism ezinhlelweni zokucabanga, futhi ezinhlobonhlobo zezinhlelo zokusebenza ze-laser ezihlanganisa imishayo eyi-elliptical ejikelezayo evela ku-laser diode, egxilisa i-beam ephambukayo kuhlu lomtshina womugqa, ukudala ishidi lokukhanya. kumasistimu wokulinganisa, noma ukukhiphela umugqa we-laser endaweni.Amalensi angama-cylindrical asetshenziswa ezimbonini eziningi ezihlanganisa ukukhanya komtshina, ukuskena kwekhodi yebha, i-spectroscopy, ukukhanya kwe-holographic, ukucubungula ulwazi olubonakalayo kanye nobuchwepheshe bekhompyutha.

Amalensi angamacylindrical anendawo eyodwa eyisicaba kanye ne-convex eyodwa, alungele izinhlelo zokusebenza ezidinga ukukhuliswa endaweni eyodwa.Ngenkathi amalensi ayindilinga esebenza ngokulinganayo ezinhlangothini ezimbili kumreyi wesigameko, amalensi ayindilinga asebenza ngendlela efanayo kodwa kuhlangothi olulodwa kuphela.Uhlelo lokusebenza olujwayelekile kungaba ukusebenzisa amalensi angama-cylindrical ukunikeza ukubunjwa kwe-anamorphic kwe-beam.Olunye uhlelo lokusebenza ukusebenzisa ilensi eyodwa ephozithivu eyisilinda ukuze ugxilise ugongolo oluphambukayo kuhlelo lomtshina;Ipheya lamalensi ayi-positive cylindrical angasetshenziswa ukuze angqubuzane futhi azungeleze okukhiphayo kwe-laser diode.Ukuze kuncishiswe ukwethulwa kokujika okuyindilinga, ukukhanya okukholalisiwe kufanele kube isigameko endaweni egobile lapho kugxiliswe emugqeni, futhi ukukhanya okuvela emthonjeni wolayini kufanele kube isigameko endaweni yeplanethi lapho kungqubuzana.

Amalensi ayisilinda angalungile anendawo eyodwa eyisicaba kanye nendawo eyodwa egobile, anobude bokugxila obunegethivu futhi asebenza njengamalensi ayindilinga e-plano-concave, ngaphandle kwe-eksisi eyodwa kuphela.Lawa ma-lens asetshenziswa ezinhlelweni ezidinga ukubunjwa kwe-dimensional eyodwa komthombo wokukhanya.Uhlelo lokusebenza olujwayelekile kungaba ukusebenzisa ilensi eyisilinda eyinegethivu eyodwa ukuguqula i-laser ehlanganisiwe ibe ijeneretha yomugqa.Amapheya amalensi ayisilinda angase asetshenziselwe ukubumba izithombe ngendlela ye-anamorphically.Ukuze unciphise ukwethulwa kokungalungi, indawo egobile yelensi kufanele ibhekane nomthombo lapho isetshenziselwa ukuphambukisa i-beam.
I-Paralight Optics inikeza amalensi ayisilinda akhiwe nge-N-BK7 (CDGM H-K9L), i-silica ehlanganiswe ne-UV, noma i-CaF2, wonke atholakala engagqokile noma ane-antireflection.Siphinde futhi sinikeze ngezinguqulo eziyindilinga zamalensi ethu ayisilinda, amalensi enduku, nama-cylindrical achromatic doublet ezinhlelweni ezidinga ukuphambuka okuncane.
