Achromatic Doublets

Lub lens achromatic, tseem hu ua achromat, feem ntau muaj 2 cov khoom siv kho qhov muag sib xyaw ua ke, feem ntau yog qhov ntsuas qis qis (feem ntau yog cov iav iav biconvex lens) thiab cov ntsiab lus tsis zoo siab (xws li flint iav).Vim yog qhov sib txawv ntawm qhov ntsuas qhov ntsuas qhov ntsuas, qhov sib txawv ntawm ob lub ntsiab lus ib nrab them rau ib leeg, chromatic aberration nrog rau ob qhov kev xaiv wavelength tau raug kho.Lawv yog optimized los kho rau ob qho tib si on-axis kheej kheej kheej thiab chromatic aberrations.Achromatic lens yuav muab qhov chaw me me thiab cov duab zoo dua li qhov sib piv singlet lens nrog tib lub focal ntev.Qhov no ua rau lawv zoo tagnrho rau kev thaij duab thiab broadband focusing applications.Achromats tau tsim thiab tsim los ua kom tau raws li qhov kev ua siab ntev tshaj plaws uas yuav tsum tau muaj nyob rau niaj hnub no cov kev ua haujlwm siab laser, electro-optical thiab cov duab kos duab.

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, 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 zoo tagnrho rau high-power. daim ntawv thov vim muaj kev puas tsuaj ntau dua li cov cemented achromats, nrog rau achromatic triplets uas tso cai rau kev tswj hwm qhov siab tshaj plaws.

Paralight Optics ' cemented Achromatic Doublets muaj nrog cov tshuaj tiv thaiv kev cuam tshuam rau thaj tsam pom ntawm 400 - 700 nm, txuas ntxiv pom thaj tsam ntawm 400 - 1100 nm, ze rau thaj tsam IR ntawm 650 - 1050 nm, lossis IR ntau ntawm 1050 - 1700 nm wavelength.Lawv tau ua kom zoo dua los muab kev ua tau zoo hauv thaj chaw pom thiab ze-infrared (NIR), cov txheej txheem txuas ntxiv (AR) ua rau lawv zoo tagnrho rau kev siv fluorescence microscopy.Thov tshawb xyuas cov duab coatings hauv qab no rau koj cov ntaub ntawv siv.Achromatic doublets yog siv los ua lub hom phiaj tsom iav, qhov muag loupes, iav tsom iav thiab eyepieces.Achromatic doublets kuj tau siv los ua kom pom tseeb thiab tswj cov kab teeb ci laser vim tias lawv cov duab zoo dua rau ib lo ntsiab muag.

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.

Cov duab

Daim duab sab xis qhia kev sib piv ntawm Reflectance Curves ntawm AR-Coated Achromatic Doublets rau qhov sib txawv wavelength ranges (Liab rau pom ntawm 400 - 700nm, Xiav rau ncua pom ntawm 400-1 100nm, Ntsuab rau ze IR ntawm 650 - 1050nm)
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 ua tiav los ntawm kev siv ntau lub ntsiab lus tsim hauv Zemax⑧ 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.
