I-Precision Aplanatic
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.Ngokuphathelene nama-achromatic doublet kanye nomugqa wama-triplets angehlisiwe, singahlinzeka ngokuphindwe kabili kwe-achromatic (kokubili okujwayelekile kanye nokunemba kwe-aplanatic), ukuphinda kabili kwecylindrical achromatic, amapheya e-achromatic doublet athuthukiselwe ama-conjugates anomkhawulo futhi alungele ukudluliswa kwesithombe nezinhlelo zokukhulisa, ama-achromatic aphindwe kabili anezikhala zomoya. ezilungele izinhlelo zokusebenza zamandla aphezulu ngenxa yomkhawulo womonakalo omkhulu kunama-achromat asimende, kanye nama-triplets angama-achromatic avumela ukulawulwa kokungalungi okukhulu.

Ama-Paralight Optics' Precision Aplanats (Ama-Aplanatic Achromatic Doublets) awalungiswa nje kuphela ngokujika okuyindilinga kanye nombala we-axial njengama-Standard Cemented Achromatic Doublets kodwa futhi alungiselelwa ikhoma.Le nhlanganisela ibenza babe yi-aplanatic ngokwemvelo futhi ilethe ukusebenza okungcono kokubona.Zisetshenziswa njengezinhloso zokugxilisa i-laser nasezinhlelweni ze-electro-optical & imaging.

Ama-double ethu e-achromatic athuthukisiwe ukuze anikeze cishe ubude obugxilile obungaguquki kuwo wonke umkhawulokudonsa obanzi.Lokhu kufezwa ngokusebenzisa ukwakheka kwezinto eziningi ku-Zemax® ukuze kuncishiswe 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.Igrafu yohlangothi lwesokudla ibonisa ukushintsha kwe-paraxial focal njengomsebenzi we-wavelength ye-achromatic doublet ebonakalayo enobude obugxilile obungu-400mm, Ø25.4 mm njengereferensi yakho.
