Lilense tsa Cylindrical
Lilense tse ntle tsa cylindrical li na le bokaholimo bo le bong bo bataletseng le bokaholimo bo le bong bo bokhutšoane, li loketse lits'ebetso tse hlokang ho holisoa boemong bo le bong. Leha lilense tse chitja li sebetsa ka mokhoa o ts'oanang ka litekanyo tse peli ho lehlaseli la ketsahalo, lilense tsa cylindrical li sebetsa ka mokhoa o ts'oanang empa ka tekanyo e le 'ngoe feela. Ts'ebeliso e tloaelehileng e ka ba ho sebelisa para ea lilense tsa cylindrical ho fana ka sebopeho sa anamorphic sa leballo. Tšebeliso e 'ngoe ke ho sebelisa lense e le 'ngoe e ntle ea cylindrical ho tsepamisa lebone le khelohang holim'a sehlopha sa detector; Lilense tse ntle tsa cylindrical li ka sebelisoa ho kopana le ho potoloha tlhahiso ea laser diode. Ho fokotsa ho kenyeletsoa ha liphapang tse chitja, khanya e kholimated e lokela ho ba sebakeng se kobehileng ha e lebisoa moleng, 'me khanya e tsoang mohloling oa mohala e lokela ho ba teng sebakeng sa plano ha ho hohlana.
Lilense tsa cylindrical tse nyahamisang li na le bokaholimo bo le bong bo sephara le bokaholimo bo le bong bo khohomo, li na le bolelele bo bobe ba ho tsepamisoa 'me li sebetsa joalo ka lilense tse chitja tsa plano-concave, ntle le axis e le' ngoe feela. Lilense tsena li sebelisoa lits'ebetsong tse hlokang sebopeho se le seng sa mohloli oa leseli. Tšebeliso e tloaelehileng e ka ba ho sebelisa lense e le 'ngoe e mpe ea cylindrical ho fetola laser e kopantsoeng hore e be jenereithara ea mohala. Lipara tsa lilense tsa cylindrical li ka sebelisoa ho theha litšoantšo ka mokhoa oa anamorphically. Ho fokotsa tlhahiso ea ho kheloha, bokaholimo bo kobehileng ba lense bo lokela ho shebana le mohloli ha bo sebelisoa ho kheloha leballo.
