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 umugqa 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) zifaka i-N-BK7 yengilazi engaphansi ene-metallic (Inconel) efakwe ohlangothini olulodwa, i-Inconel iyingxube yensimbi eqinisekisa ukusabela kwe-spectral eyisicaba kusukela ku-UV kuya ku-IR eseduze; Izihlungi ze-silica ezihlanganisiwe ze-UV ziqukethe i-UVFS substrate ene-nickel coating efakwe ohlangothini olulodwa, enikeza impendulo eyisicaba ye-spectral; 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.

Ijika Lokudlulisa lezihlungi ze-infrared reflective neutral zokuminyana nokuminyanisa kokubona kusuka ku-0.3 kuye ku-3.0 (ijika eliluhlaza okwesibhakabhaka: ND 0.3, ijika eliluhlaza: 1.0, ijika elolintshi: ND 2.0, ijika elibomvu: ND 3.0), lezi zihlungi ziqukethe i-ZnSel substrate ukumboza ohlangothini olulodwa ngaphezu kobubanzi be-wavelength obungu-2 ukuya ku-16 µm. Ukuze uthole imininingwane eyengeziwe ngezinye izinhlobo zezihlungi ze-ND, sicela usithinte.
