Lub lens achromatic siv rau dab tsi? Lub lens uas yog tsim tshwj xeeb los tswj cov teebmeem ntawm chromatic distortion lossis aberration(ib qho tsis xws ntawm cov lo ntsiab muag kho qhov muag kom ua kom pom tseeb ntawm tag nrho cov xim rau tib lub ntsiab lus convergence) hu ua achromatic lens. Nws yog dav paub tias yog 'achromat'.
achromatic lo ntsiab muag siv rau dab tsi?
Ib lub lens achromatic lossis achromat yog lub lens uas yog tsim los txwv cov teebmeem ntawm chromatic thiab spherical aberration. Achromatic lo ntsiab muag raug kho kom coj ob lub wavelengths (feem ntau xim liab thiab xiav) los tsom rau tib lub dav hlau.
achromatic lo ntsiab muag siv nyob qhov twg?
Achromatic doublets yog dav siv los tsim cov duab, piv txwv li lub hom phiaj tsom iav, thiab tseem tsom rau cov kab teeb ci laser. Cov achromats zoo no tau tsim thiab ua kom zoo rau kev ua haujlwm thiab muaj xws li hom zoo thiab qhov tsis zoo focal ntev.
Achromat yog dab tsi?
Nrog rau tag nrho cov aperture meej siv, lub lens achromatic thiab achromatic lens tshuab tau nrawm dua, ntau dua, thiab muaj zog dua li cov tshuab sib npaug siv lo ntsiab muag singlet. Muaj ntau yam txheej tiv thaiv kev cuam tshuam thiab tsim kev xaiv rau UV, pom, lossis IR spectrum.
Lub hom phiaj ntawm achromatic doublet yog dab tsi?
Ib qho ntawm cov qauv kho qhov muag feem ntau yog achromatic doublet. Nws yog siv los txo cov chromatic aberrationsNtawm nws qhov yooj yim tshaj plaws, nws yog ob lub lens system teeb tsa qhov twg ib lub lens yog lub lens concave, feem ntau yog ua los ntawm iav flint, thiab lwm qhov yog convex. element, feem ntau yog ua los ntawm yas yas.
