Absorptive/Reflective Neutral Density Filters

Optical density (OD) qhia txog qhov attenuation factor uas muab los ntawm lub tshuab kho qhov muag, piv txwv li nws txo lub zog kho qhov muag ntawm qhov teeb meem kab teeb. OD muaj feem xyuam rau kev sib kis. Xaiv lub ND lim nrog lub qhov muag pom ntau dua yuav hloov mus rau qis dua thiab kev nqus ntau dua ntawm qhov teeb meem teeb meem. Rau kev sib kis ntau dua thiab kev nqus tsawg dua, qhov qis dua qhov muag pom yuav tsim nyog. Piv txwv li, yog tias lub lim nrog OD ntawm 2 ua rau tus nqi sib kis ntawm 0.01, qhov no txhais tau hais tias lub lim attenuates lub nqaj mus rau 1% ntawm qhov teeb meem fais fab. Muaj feem ntau ob hom filiters: absibrptive tsis muaj zog lim, muaj cov lim dej nruab nrab ntawm nruab nrab.

Peb qhov kev nqus kom ceev (ND) cov ntxaij lim dej muaj nyob rau ntau qhov sib txawv nrog qhov sib txawv nrog cov qauv siv kho mob (OD) xws li 0.1 rau 8.0. Tsis zoo li lawv cov kev xav, cov khoom siv hlau nplaum, txhua qhov ND lim yog tsim los ntawm lub substrate ntawm Schott iav uas tau raug xaiv rau nws cov spectrally tiaj tus nqus coefficient hauv thaj tsam pom los ntawm 400 nm txog 650 nm.

Reflective neutral density filters muaj nyob nrog N-BK7 (CDGM H-K9L), UV Fused Silica (JGS 1), lossis Zinc Selenide substrate nyob rau hauv ntau yam spectral. N-BK7 (CDGM H-K9L) cov ntxaij lim dej muaj N-BK7 iav substrate nrog cov xim hlau (Inconel) txheej tso rau ntawm ib sab, Inconel yog cov hlau nplaum uas ua kom cov lus teb tiaj tus los ntawm UV mus rau IR nyob ze; UV fused silica filters muaj UVFS substrate nrog cov nickel txheej tso rau ntawm ib sab, uas muab cov lus teb tiaj tus spectral; Znse Unens lim muaj cov Znse substrate (kho qhov muag pom ntawm ib sab, thov saib cov duab sab nraud uas muaj ntau, thov saib cov duab kos hauv qab no rau koj cov ntawv pov thawj.
