I-Standard Cemented
I-Achromatic Doublets

Ilensi ye-achromatic, eyaziwa nangokuthi i-achromat, ngokuvamile iqukethe izingxenye ezimbili ze-optical ezihlanganiswe ndawonye, ​​ngokuvamile into ephozithivu yenkomba ephansi (imvamisa i-crown glass biconvex lens) kanye ne-negative high index element (njenge-flint glass). Ngenxa yomehluko kuma-indices e-refractive, ukuhlakazwa kwama-elementi amabili kunxephezela kancane enye kwenye, ukushintshashintsha kwe-chromatic ngokuphathelene namaza wamaza amabili akhethiwe kulungisiwe. Athuthukisiwe ukuze alungise kukho kokubili i-on-axis spherical and chromatic aberrations. Ilensi ye-Achromatic izohlinzeka ngosayizi omncane wendawo kanye nekhwalithi yesithombe ephakeme kunelensi eyodwa eqhathaniswayo enobude bokugxila obufanayo. Lokhu kubenza balungele izinhlelo zokusebenza zokugxilisa izithombe kanye ne-broadband. Ama-Achromats aklanywe futhi akhiqizwa ukuze enelise ukubekezelelana okuqinile okudingekayo kumasistimu anamuhla e-laser, i-electro-optical kanye ne-imaging yanamuhla.

I-Paralight Optics inikezela ngezinhlobonhlobo ze-achromatic optics yangokwezifiso enosayizi abachazwe ngamakhasimende, ubude bokugxila, izinto ze-substrate, izinto zikasimende, nezingubo zokugqoka zenziwe ngokwezifiso. Amalensi ethu e-achromatic amboza u-240 – 410 nm, 400 – 700 nm, 650 – 1050 nm, 1050 – 1620 nm, 3 – 5 µm, kanye no-8 – 12 µm ububanzi begagasi. Atholakala ehlisiwe, agitshelisiwe noma ngamapheya afanisiwe. Mayelana nama-achromatic doublet kanye nomugqa wama-triplets angehlisiwe, singahlinzeka ngokuphindwe kabili kwe-achromatic, ama-achromatic double cylindrical, amapheya e-achromatic doublet alungiselelwe ama-conjugates anomkhawulo futhi alungele ukudluliselwa kwesithombe nezinhlelo zokukhulisa, ama-achromatic aphindwe kabili anezikhala zomoya alungele amandla aphezulu. izinhlelo zokusebenza ngenxa yomkhawulo womonakalo omkhulu kunama-achromat asimende, kanye nama-triplets angama-achromatic avumela ukulawulwa kokungalungi okukhulu.

Ama-Achromatic Doublets e-Paralight Optics atholakala ngokujikijelwa kwe-antireflection endaweni ebonakalayo engu-400 – 700 nm, indawo ebonakalayo enwetshiwe engu-400 – 1100 nm, eduze nesifunda se-IR esingu-650 – 1050 nm, noma ububanzi be-IR obungu-1050 – 1700 nm ububanzi. Athuthukiswe ukuze anikeze ukusebenza okuhle kakhulu ezindaweni ezibonakalayo neziseduze ne-infrared (NIR), i-extended antireflection (AR) inamathela izenza zilungele izinhlelo zokusebenza ze-fluorescence microscopy. Sicela uhlole igrafu elandelayo yama-coatings ukuze uthole izinkomba zakho. Okuphindwe kabili kwe-Achromatic asetshenziswa njengezinhloso zetheleskopu, ama-eye loupes, izibuko ezikhulisayo kanye neziqeshana zamehlo. Okuphindwe kabili kwe-Achromatic nakho kusetshenziselwe ukugxila kanye nokukhohlisa imishayo ye-laser ngoba ikhwalithi yesithombe sabo ingaphezu kwamalensi awodwa.

Amagrafu

Igrafu engakwesokudla ibonisa Ukuqhathaniswa kwama-Reflectance Curves of AR-Coated Achromatic Doublets kububanzi obungangeni obuhlukene (Bomvu ngokubonakala kuka-400 - 700nm, Okuluhlaza okwesibhakabhaka ngokubonakala okunwetshiwe okungu-400-1 100nm, Okuluhlaza ngokuseduze kwe-IR ka-650 - 1050nm)
I-Focal Shift vs. Wavelength
Ama-double ethu e-achromatic athuthukisiwe ukuze anikeze cishe ubude obugxilile obungaguquki kuwo wonke umkhawulokudonsa obanzi. Lokhu kufezwa ngokusebenzisa ukwakheka kwezinto eziningi ku-Zemax⑧ukunciphisa ukuphuma kwe-chromatic kwelensi. Ukuhlakazeka engilazini yokuqala eyiphozithivu yomqhele we-doublet kulungiswa isigaba se-flint esinegethivu sesibili, okuholela ekusebenzeni okungcono kwe-broadband kunama-singlets ayindilinga noma amalensi ase-aspheric.
Amagrafu angezansi abonisa ukushintsha kwe-paraxial focal njengomsebenzi we-wavelength kumasampuli amathathu ahlukene e-achromatic doublet esithenjwa sakho.
