Meniscus Lens Negative Meniscus hauv Cov tsom iav

Lub lens meniscus yog ib lub lens spherical nrog ib qho convex (outwardly curved) nto thiab ib qho concave (inwardly curved) nto. Qhov nkhaus ntawm ob qhov chaw sib ntsib ntawm ntug, muab lub lens ib lub crescent lossis 'meniscus' duab. Cov duab meniscus muab qee qhov txiaj ntsig kho qhov muag thiab cov txiaj ntsig rau kev tsom thiab xa lub teeb. Nws ua rau ntau yam kev siv uas nws lub zog tuaj yeem siv tau, suav nrog cov tsom iav tsom iav yooj yim, condenser lo ntsiab muag, lub ntsej muag lub ntsej muag, thiab lub ntsej muag yees duab.

 

Peb muab cov khoom zoo meniscus lo ntsiab muag uas muab kev pom zoo ntawm kev ua haujlwm kho qhov muag thiab kev ua haujlwm ntev. Peb qhov tseeb hauv av thiab polished iav meniscus optics leverage cov txiaj ntsig zoo ntawm cov duab meniscus kom muab koj lub tshuab kho qhov muag ua haujlwm tseem ceeb. Lawv kuj khav theeb kis tau tus mob siab txawm tias qhov dav dav qhov ntau thiab tsawg vim qhov nqus tau tsawg dua. Cov duab nkhaus kuj muab cov cuab yeej zoo -- faib cov quab yuam kom tsis txhob muaj kev puas tsuaj nyob rau hauv kev ntxhov siab. Thov hu rau peb niaj hnub no kom paub seb peb tuaj yeem txhim kho koj daim ntawv thov li cas nrog cov txiaj ntsig ntawm peb cov nqi meniscus optics muab. Kev cai lens tsim kuj muaj rau OEM. Koj qhov system yuav pom qhov txawv!

Daim ntawv thov

Cov ntawv thov tseem ceeb tshaj plaws ntawm cov lo ntsiab muag meniscus siv lawv lub peev xwm los txo cov kheej kheej aberration, muab qhov dav aperture lossis thaj chaw saib, tsom lossis khaws lub teeb ntawm ntau lub kaum ntse ntse, thiab ua tiav cov duab zoo rau lawv cov tuab. Lawv cov duab ua rau lawv muaj txiaj ntsig zoo rau cov tshuab kho qhov muag uas yooj yim thiab sophisticated thoob plaws ntau thaj chaw ntawm kev tshawb fawb thiab thev naus laus zis.

Qhov txawv ntawm qhov zoo thiab qhov tsis zoo yog dab tsimeniscus lo ntsiab muags?

Qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo ntawm cov lo ntsiab muag meniscus los rau curvature ntawm lawv qhov chaw:

• Lub lens zoo muaj qhov convex (outwardly curving) nto nrog lub vojvoog luv ntawm curvature thiab concave (inwardly curving) nto nrog lub vojvoog ntev dua. Cov duab no ua rau lub lens converge thiab tsom teeb, ua raws li lub iav magnifying. Cov lo ntsiab muag zoo yog qhov nkhaus nkhaus thiab muaj lub zog tsom ntau dua.

 

• Lub lens tsis zoo muaj lub ntsej muag concave nrog lub vojvoog luv ntawm curvature thiab convex nto nrog lub vojvoog ntev dua. Cov duab no ua rau lub lens diverge lub teeb, ua raws li lub lens diffusing. Cov lo ntsiab muag tsis zoo muaj lub ntsej muag zoo nkauj, qis dua nkhaus thiab txo lub zog tsom.

 

Qee qhov sib txawv tseem ceeb yog:

Focal Length:

• Qhov zoo: luv dua focal ntev, raws li nws tsom lub teeb muaj zog. Lub zog yog ntsuas hauv qhov zoo diopters.

• Tsis zoo: ntev focal ntev, raws li nws diffuses lub teeb tsis muaj zog. Lub zog yog ntsuas hauv qhov tsis zoo diopters.

 

Aberrations:

• Zoo: ntau dua spherical aberration vim yog qhov nkhaus heev. Yooj yim kho.

• Tsis zoo: Txo cov kheej kheej aberration vim qhov chaw flatter. Yooj yim ua rau hauv aberration-corrected lens.

 

Daim ntawv thov:

• Zoo: Siv los ua ib lub iav magnifying los yog rau collimating (ua parallel) divergent lub teeb. Ua haujlwm hauv condensers, projectors, thiab magnifiers.

• Tsis zoo: Siv los diffuse thiab diverge ib qho pib sib tsoo beam. Pom muaj nyob rau hauv cov ntawv thov uas xav tau ib qho kev tso zis sib txawv, xws li barcode scanners.

 

Lens zog:

• Zoo: Ntsuas hauv qhov zoo diopters (xws li, ntxiv rau 10 D), qhia txog kev sib tshuam ntawm lub teeb.

• Tsis zoo: Ntsuas hauv qhov tsis zoo diopters (piv txwv li, -5 D), qhia qhov sib txawv ntawm lub teeb.

 

Yog li, nyob rau hauv qhov tseeb, thaum tag nrho cov meniscus lo ntsiab muag qhia ib co khoom xws li durability thiab aberration kho, zoo thiab tsis zoo lo ntsiab muag txawv heev nyob rau hauv lawv cov duab, focal lengths, thiab lub hwj chim, raws li zoo raws li lawv cov kev siv. Txawm li cas los xij, ua kom txaus thiab ntsuas ntsuas, tuaj yeem pab tau - nws nyob ntawm seb koj puas xav tau tsom thiab nthuav lub teeb los yog diverge thiab diffuse nws.
