Izihlungi Ze-Absorptive/Reflective Neutral Density Density

I-Optical density (OD) ikhombisa isici sokunciphisa esinikezwa yisihlungi sokubona, okungukuthi sinciphisa kangakanani amandla okubona we-beam yesigameko.I-OD ihlobene nokudluliswa.Ukukhetha isihlungi se-ND esinokuminyana okuphezulu kwe-optical kuzohumushela ekudluliselweni okuphansi kanye nokumuncwa okukhulu kokukhanya kwesigameko.Ukuze uthole ukudluliswa okuphezulu nokumuncwa okuncane, ukuminyana okuphansi kokukhanya kuzofaneleka.Njengesibonelo, uma isihlungi esine-OD ka-2 siphumela enanini lokudlulisela elingu-0.01, lokhu kusho ukuthi isihlungi sinciphisa i-beam ku-1% wamandla esigameko.Kunezinhlobo ezimbili eziyisisekelo zezihlungi ze-ND: izihlungi zokuminyana ezingathathi hlangothi, izihlungi zokuminyana ezibonakala maphakathi.

Izihlungi zethu ze-absorptive neutral density (ND) zitholakala ngosayizi abahlukahlukene ngokuminyana kokubona (OD) ukusuka ku-0.1 kuye ku-8.0.Ngokungafani nozakwabo abakhanyayo, bensimbi, isihlungi ngasinye se-ND sakhiwe sisuka ku-substrate yengilazi ye-Schott ekhethelwe i-spectrally flat coefficient yokumuncwa endaweni ebonakalayo ukusuka ku-400 nm kuya ku-650 nm.

Izihlungi ze-reflective neutral density ziyatholakala nge-N-BK7 (CDGM H-K9L), UV Fused Silica (JGS 1), noma i-Zinc Selenide substrate kububanzi obuhlukahlukene bokubukeka.Izihlungi ze-N-BK7 (CDGM H-K9L) zihlanganisa ingilazi engaphansi engu-N-BK7 ene-metallic (Inconel) enamathela efakwe ohlangothini olulodwa, i-Inconel iyingxubevange yensimbi eqinisekisa impendulo ye-spectral eyisicaba kusukela ku-UV kuya ku-IR eseduze;Izihlungi ze-silica ezihlanganisiwe ze-UV zihlanganisa i-UVFS substrate ene-nickel coating efakwe ohlangothini olulodwa, okunikeza impendulo ye-spectral eyisicaba;Izihlungi ze-ZnSe neutral density ziqukethe i-ZnSe substrate (ukuminyana kokubona okusuka ku-0.3 kuye ku-3.0) ezinombala we-nickel ohlangothini olulodwa, okuholela ekuphenduleni kwe-spectral eyisicaba phezu kobubanzi be-wavelength obungu-2 ukuya ku-16 µm, sicela ubone igrafu elandelayo ukuze uthole izithenjwa zakho.
