Precision Aplantic
Achromatic Doublets
Paralight Optics muaj ntau yam kev cai achromatic optics nrog cov neeg siv khoom-txhais qhov ntau thiab tsawg, focal lengths, substrate cov ntaub ntawv, cov ntaub ntawv cement, thiab coatings yog kev cai tsim.Peb achromatic lo ntsiab muag npog 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm, thiab 8 - 12 µm wavelength ranges.Lawv muaj nyob rau hauv unmounted, mounted los yog matched khub.Hais txog unmounted achromatic doublets & triplets kab-up, peb muaj peev xwm muab achromatic doublets (ob tus qauv thiab precision aplanatic), cylindrical achromatic doublets, achromatic doublet khub uas yog optimized rau finite conjugates thiab zoo tagnrho rau cov duab relay thiab magnification systems, air-spaced achromatic doublets. uas yog qhov zoo tshaj plaws rau kev siv hluav taws xob siab vim muaj kev puas tsuaj ntau dua li cov cemented achromats, nrog rau cov achromatic triplets uas tso cai rau kev tswj xyuas qhov siab tshaj plaws.
Paralight Optics 'Precision Aplanats (Aplanatic Achromatic Doublets) tsis yog tsuas yog kho rau spherical aberration thiab axial xim raws li Standard Cemented Achromatic Doublets tab sis kuj kho rau coma.Qhov kev sib xyaw ua ke no ua rau lawv aplanatic hauv qhov xwm txheej thiab xa cov kev ua haujlwm kho qhov muag zoo dua.Lawv yog siv los ua laser tsom lub hom phiaj thiab hauv electro-optical & imaging systems.
Nta:
Cov txiaj ntsig:
Tsawg kawg ntawm Axial Chromatic & Spherical Aberration
Sib piv rau Standard Achromatic Doublets:
Ua kom zoo kom raug rau Coma
Optical Performance:
Aplanatic nyob rau hauv Xwm thiab xa zoo Optical Performance
Daim ntawv thov:
Laser Focusing thiab hauv Electro-Optical & Imaging Systems

Lus Cim: Rau kev ua tau zoo tshaj plaws thaum sib tsoo qhov chaw taw tes, feem ntau yog thawj cov huab cua-rau-iav interface nrog lub vojvoog ntau dua ntawm curvature (flatter side) yuav tsum fim deb ntawm lub refracted collimated beam, conversely thaum tsom ib tug collimated beam, huab cua-rau -glass interface nrog lub vojvoog luv luv ntawm curvature (qhov nkhaus ntau dua) yuav tsum fim qhov xwm txheej sib tsoo beam.

Focal Shift vs. Wavelength
Peb achromatic doublets yog optimized los muab ib tug ze li ntawm qhov focal ntev nyob rau hauv ib tug dav bandwidth.Qhov no yog ua tiav los ntawm kev siv ntau lub ntsiab lus tsim hauv Zemax® kom txo qis chromatic aberration ntawm lub lens.Dispersion nyob rau hauv thawj qhov zoo yas iav ntawm lub doublet yog kho los ntawm lub thib ob tsis zoo flint chav kawm ntawv, ua rau kom zoo broadband kev ua tau zoo dua spherical singlets los yog aspheric lo ntsiab muag.Daim duab sab xis qhia tau hais tias paraxial focal hloov raws li kev ua haujlwm ntawm wavelength rau pom achromatic doublet nrog lub focal ntev ntawm 400mm, Ø25.4 hli rau koj siv.
