Cov Iav Lens Aspheric Cylindrical Zoo Tshaj Plaws Rau Precision Optics

Kev piav qhia txog khoom

Cov iav aspheric cylindrical feem ntau yog semi-cylindrical. Piv nrog rau cov iav, cov iav cylindrical sib sau ua ke lossis sib cais lub teeb pom kev raws txoj kab focal es tsis yog qhov focal, uas yog siv dav hauv ntau yam lag luam thiab teb xws li cov cuab yeej siv kho qhov muag, cov khoom siv thaij duab, kev sib txuas lus kho qhov muag, kev thaij duab kho mob, kev ua laser thiab lwm yam. Nws muab cov txiaj ntsig ntawm cov iav aspherical thiab cov iav cylindrical ua ke, thiab muab cov cuab yeej muaj zog rau cov neeg tsim kho qhov muag los ua kom zoo dua qhov kev ua tau zoo ntawm lub cev kho qhov muag, txo qhov aberration thiab txhim kho qhov zoo ntawm cov duab. Nws qhov kev ua tau zoo ntawm qhov muag yog cuam tshuam nrog cov ntaub ntawv. Cov iav aspherical cylindrical iav yog siv dav hauv cov kab ke kho qhov muag thiab cov khoom siv kho mob vim nws qhov kev ua tau zoo ntawm qhov muag thiab kev ua haujlwm ntev.

Nta:

(1) Tsim qauv tsis sib npaug:Kev tsim qauv aspherical ntawm lub lens cylindrical aspherical pab txo qhov aberration, tshwj xeeb tshaj yog spherical aberration thiab astigmatism, yog li muab cov duab pom tseeb dua;

(2) Kev tsom mus rau ib qho:Vim nws cov yam ntxwv cylindrical, lub lens no tuaj yeem tsom lossis diffuse lub teeb rau hauv ib qho kev taw qhia, thaum nyob rau hauv lwm qhov ntev perpendicular rau qhov kev taw qhia no, lub teeb kis tau yuav luag tsis cuam tshuam;

(3) Lub teeb ci ntsa iab:Cov khoom siv iav muaj lub teeb ci ntsa iab kom ntseeg tau tias lub zog ntawm lub teeb kis tau zoo;

(4) Kev Ruaj Khov:Cov khoom siv iav feem ntau ruaj khov thiab tsim nyog rau kev siv mus sij hawm ntev;

(5) Kev hloov kho tshwj xeeb heev:Lub lens cylindrical aspheric tuaj yeem hloov kho raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb, suav nrog nws qhov loj me, curvature, aspheric coefficient thiab txheej;

(6) Txhim kho kev ua haujlwm ntawm lub kaw lus:Kev siv lub lens no tuaj yeem txhim kho qhov kev ua tau zoo ntawm lub kaw lus kho qhov muag yam tsis ua rau lub kaw lus nyuaj dua.

Cov txiaj ntsig:

(1) Txo qhov txawv txav:Qhov kev hloov pauv ntawm lub voj voog thiab lwm yam kev hloov pauv hauv lub cev kho qhov muag tau raug txo kom zoo los ntawm kev tsim qauv aspheric;

(2) Kev tsom mus rau qhov tseeb siab:nws tuaj yeem ua tiav qhov kev tsom teeb pom kev zoo hauv ib qho kev taw qhia, uas yog qhov tsim nyog rau cov ntawv thov uas xav tau kev tswj hwm lub teeb zoo;

(3) Txhim kho kev ua haujlwm ntawm lub kaw lus:Tag nrho cov kev ua tau zoo thiab kev ua haujlwm ntawm lub tshuab kho qhov muag tau zoo dua yam tsis tau ntxiv cov khoom siv kho qhov muag ntxiv;

(4) Kev hloov kho tau yooj yim:nws tuaj yeem hloov kho raws li qhov xav tau ntawm daim ntawv thov tshwj xeeb kom tau raws li qhov xav tau tsim kho qhov muag sib txawv.
