Cylindrical Lens Rau Astigmatism

Lub cylindrical lo ntsiab muag muaj qhov chaw nkhaus uas tsom lossis nthuav tawm lub teeb hauv ib qho kev taw qhia xwb. Lawv muaj refracting zog nyob rau hauv ib tug meridian. Cylindrical optical lo ntsiab muag ncaj qha lub teeb tsis sib npaug ntawm qhov sib txawv axes- khoov lub teeb ntau hauv ib qho kev txiav txim dua lwm qhov. Lawv cov khoom tshwj xeeb txhais ua cov txiaj ntsig tseem ceeb rau ntau tus neeg thiab cov tshuab pom. Cylindrical optics ntsiab, feem ntau siv ua ke nrog cov lo ntsiab muag kheej kheej, ua rau chav kawm optics tseem ceeb.

 

Peb tsim cov phiaj xwm cylindrical lo ntsiab muag nrog micron-theem nto qhov tseeb siv cov cuab yeej CNC sib tsoo thiab polishing siab heev. Peb lub chaw ntsuas ntsuas ntsuas kom zoo thoob plaws txhua qhov kev qhia tshwj xeeb - suav nrog lub zog saum npoo, nkhaus vojvoog, qhov taw qhia qhov taw qhia, thiab qhov ntev ntev. Dhau li ntawd, peb muab ceev ceev turnaround ntawm tus nqi sib tw rau prototypes thiab ntim ntau lawm. Tshawb nrhiav yuav ua li cas peb 20 xyoo kev txawj ntse hauv cylindrical optics tuaj yeem pab txhawb koj cov khoom tsim thiab kev vam meej hauv kev lag luam. Hu rau peb hnub no los tham txog koj qhov kev saib xyuas tsis pom kev, laser, duab, lossis qhov xav tau -- peb tos ntsoov yuav tsim cov kev daws teeb meem tshiab rau koj!

Daim ntawv thov

Thawj daim ntawv thov yog kho qhov muag tsis pom kev rau cov neeg astigmatic. Lawv tau tso cai rau ntau lab tus neeg los kho lawv cov astigmatism thiab ua kom pom tseeb, tsom mus rau qhov pom zoo. Lwm cov kev siv me me ntawm cov cylindrical lo ntsiab muag suav nrog kev sib tsoo lub teeb tuav, tsim cov kab foci, thiab shaping laser beams.

Dab tsi yog qhov txawv ntawm spherical thiabcylindrical lenss?

Qhov sib txawv tseem ceeb ntawm lub ntsej muag kheej kheej thiab cylindrical yog:

 

• Curvature ntawm lens nto:

- Cov lo ntsiab muag kheej kheej muaj lub ntsej muag lub ntsej muag nrog lub voj voos, zoo li cov seem ntawm ib sab.

- Cylindrical optical lo ntsiab muag muaj lub ntsej muag lens nrog curvature hauv ib qho kev taw qhia (cylindrical curvature). Nyob rau hauv lwm txoj kev, lub nto yog tiaj tus.

 

• Refraction ntawm lub teeb:

- Spherical lo ntsiab muag refract (khoov) lub teeb sib npaug hauv txhua qhov kev qhia.

- Cylindrical optics tsuas yog refract lub teeb thaum uas tig mus rau lub lens cylindrical axis. Lub teeb perpendicular rau lub axis no tsis refracted.

 

• Cov ntawv thov:

- Cov lo ntsiab muag kheej kheej feem ntau yog siv rau hauv daim ntawv thov qhov sib npaug ntawm qhov sib npaug ntawm txhua qhov kev taw qhia, piv txwv li, tsom iav tsom iav, tsom iav lo ntsiab muag, thiab lub ntsej muag yees duab.

- Cylindrical optics yog siv qhov twg refraction yuav tsum sib txawv nyob rau hauv ntau cov lus qhia, xws li, nyob rau hauv astigmatism kho, imaging systems nrog txawv magnifications nyob rau hauv lwm qhov ntev, thiab laser beam shaping.

 

• Aberrations:

- Cov lo ntsiab muag kheej kheej raug kev txom nyem los ntawm kev sib txawv ntawm qhov sib txawv vim qhov sib txawv ntawm lub zog refractive ntawm lub teeb rays dhau los ntawm ntau qhov chaw ntawm lub lens. Cylindrical lo ntsiab muag tsis muaj qhov aberration.

- Cylindrical optics muaj astigmatic aberration rau oblique xwm txheej teeb, uas kheej kheej lo ntsiab muag tsis muaj.

 

• Focal point:

- Cov lo ntsiab muag kheej kheej muaj ib qho chaw focal.

- Cylindrical optical lo ntsiab muag muaj ob kab focal - ib qho mus rau lub cylindrical axis thiab ib qho perpendicular.
