Hom thiab kev siv ntawm prisms

Prism yog ib qho khoom siv kho qhov muag uas cuam tshuam lub teeb ntawm cov ces kaum tshwj xeeb raws li nws qhov xwm txheej thiab tawm lub kaum sab xis.Prisms feem ntau yog siv hauv cov tshuab kho qhov muag los hloov cov kev taw qhia ntawm txoj kev teeb pom kev zoo, tsim cov duab inversions lossis deflections, thiab pab kom scanning functions.

Prisms siv los hloov cov kev taw qhia ntawm lub teeb beam feem ntau yuav muab faib ua reflecting prism thiab refracting prism

Reflecting prisms yog tsim los ntawm kev sib tsoo ib los yog ntau dua qhov chaw ntawm lub iav siv lub hauv paus ntsiab lus ntawm tag nrho cov sab hauv kev xav thiab txheej tshuab.Tag nrho cov kev xav sab hauv tshwm sim thaum lub teeb pom kev zoo los ntawm sab hauv lub prism mus txog qhov chaw ntawm lub kaum sab xis siab dua lub kaum sab xis tseem ceeb rau tag nrho cov kev xav sab hauv, thiab tag nrho cov teeb pom kev zoo rov qab los rau hauv.Yog tias tag nrho cov teeb pom kev sab hauv ntawm qhov teeb meem tshwm sim tsis tuaj yeem tshwm sim, ib qho xim hlau reflective txheej, xws li nyiaj, aluminium, lossis kub, yuav tsum tau muab tso rau ntawm qhov chaw kom txo qis lub zog ntawm lub teeb pom kev.Tsis tas li ntawd, txhawm rau nce cov kev hloov pauv ntawm prism thiab txo los yog tshem tawm cov khoom loj me me tau muab tso rau hauv cov inlet thiab qhov hluav taws xob ntawm kev khav theeb.

Muaj ntau hom kev cuam tshuam prisms nyob rau hauv ntau yam duab.Feem ntau, nws tuaj yeem muab faib ua prisms yooj yim (xws li lub kaum sab xis prism, pentagonal prism, Dove prism), lub ru tsev prism, pyramid prism, compound prism, thiab lwm yam.

Refracting prisms yog raws li lub hauv paus ntsiab lus ntawm lub teeb refraction.Nws muaj ob qhov chaw refractive, thiab cov kab tsim los ntawm kev sib tshuam ntawm ob qhov chaw yog hu ua ntug refractive.Lub kaum sab xis ntawm ob qhov chaw refracting yog hu ua lub kaum sab xis ntawm lub prism, sawv cev los ntawm α.Lub kaum sab xis ntawm qhov hluav taws xob tawm thiab qhov teeb meem hluav taws xob yog hu ua lub kaum sab xis sib txawv, sawv cev los ntawm δ.Rau ib tug muab prism, lub kaum sab xis refraction α thiab refractive index n yog qhov tseem ceeb, thiab lub deflection lub kaum sab xis δ ntawm lub refractive prism tsuas yog hloov nrog qhov xwm txheej kaum I ntawm lub teeb rays.Thaum txoj kev kho qhov muag ntawm lub teeb yog symmetrical nrog lub refracting prism, qhov tsawg kawg nkaus tus nqi ntawm lub deflection lub kaum sab xis yog tau, thiab cov lus qhia yog:

Optical wedge lossis wedge prism yog hu ua prism nrog lub kaum ntse ntse me me.Vim yog lub kaum sab xis refraction tsis pom zoo, thaum lub teeb tshwm sim vertically lossis ze li ntawm vertically, qhov kev qhia rau lub kaum sab xis ntawm lub npoo tuaj yeem kwv yees li yooj yim li: δ = (n-1) α.

Txheej yam ntxwv:

Feem ntau, aluminium thiab silver reflective films yog siv rau ntawm prism's reflector nto los txhim kho lub teeb pom kev zoo.Anti-reflection films kuj tau coated rau ntawm qhov xwm txheej thiab tawm qhov chaw kom nce lub teeb xa mus thiab txo cov teeb pom kev zoo hla ntau yam UV, VIS, NIR, thiab SWIR bands.

Daim ntawv thov teb: Prisms nrhiav kev siv dav hauv cov khoom siv digital, kev tshawb fawb tshawb fawb, cov cuab yeej kho mob, thiab lwm yam.- Cov cuab yeej siv digital: koob yees duab, TVs kaw (CCTVs), projectors, koob yees duab digital, digital camcorders, CCD lo ntsiab muag, thiab ntau yam khoom siv kho qhov muag.- Kev tshawb fawb tshawb fawb: telescopes, microscopes, theem / tsom rau kev ntsuas ntiv tes lossis pom phom;hnub ci converters;ntsuas ntsuas ntawm ntau hom.- Cov cuab yeej kho mob: cystoscopes / gastroscopes nrog rau cov khoom siv kho mob laser sib txawv.

Jiujon Optics muaj ntau yam khoom prism xws li lub kaum sab xis prisms ua los ntawm H-K9L iav los yog UV fused quartz.Peb muab pentagon prisms, Dove prisms, Roof prisms, ces kaum-lub voos xwmfab prisms, UV fused silica ces kaum-lub voos xwmfab prisms, thiab wedge prisms haum rau ultraviolet (UV), pom lub teeb (VIS), ze-infrared (NIR) bands nrog txawv precision qib.
Cov khoom no yog coated zoo li txhuas / nyiaj / kub reflection zaj duab xis / anti-reflection film / nickel-chromium tiv thaiv / dub xim tiv thaiv.
Jiujon muab cov kev pabcuam prism customized raws li koj qhov kev xav tau tshwj xeeb.Qhov no suav nrog kev hloov pauv hauv qhov loj / qhov tsis zoo / txheej nyiam thiab lwm yam. Thov hu rau peb kom paub meej ntxiv.
