Absorptive/Reflective Neutral Density Filters

Optical density (OD) inoratidza iyo attenuation factor inopiwa neoptical sefa, kureva kuti inoderedza zvakadii simba rekuona kwedanda rechiitiko.OD ine chekuita nekutapurirana.Kusarudza ND sefa ine yakakwira optical density inoshandura kudzikisa kutapurirana uye kunyura kwakanyanya kwechiedza chechiitiko.Pakutapurirana kwepamusoro uye kunyura kushoma, density yakaderera yemaziso ingave yakakodzera.Semuenzaniso, kana sefa ine OD ye2 ikaburitsa kukosha kwe0.01, izvi zvinoreva kuti sefa inorebesa danda ku1% yesimba rechiitiko.Kune mhando mbiri dzeND mafirita: absorptive neutral density mafirita, anotaridza kwaakarerekera density mafirita.

Yedu absorptive neutral density (ND) mafirita anowanikwa muhukuru hwakasiyana ane optical densities (OD) kubva 0.1 kusvika 8.0.Kusiyana neavo anotarisisa, masimbi anofananidzira, imwe neimwe ND sefa inogadzirwa kubva kune substrate yeSchott girazi iyo yakasarudzwa kune yayo inotaridzika flat absorption coefficient munharaunda inoonekwa kubva 400 nm kusvika 650 nm.

Reflective neutral density mafirita anowanikwa neN-BK7 (CDGM H-K9L), UV Fused Silica (JGS 1), kana Zinc Selenide substrate mune akasiyana spectral renji.N-BK7 (CDGM H-K9L) mafirita anosanganisira N-BK7 girazi substrate ine simbi (Inconel) coating yakaiswa kune rumwe rutivi, Inconel isimbi yesimbi inovimbisa kuti flat spectral mhinduro kubva kuUV kusvika pedyo neIR;UV yakasanganiswa silica mafirita ane UVFS substrate ine nickel coating yakaiswa kune rimwe divi, iyo inopa flat spectral mhinduro;ZnSe neutral density filters ine ZnSe substrate (Optical density inotangira pa0.3 kusvika 3.0) ine nickel coating kune rimwe divi, zvinotungamira kune rakati rara spectral mhinduro pamusoro pe2 kusvika 16 µm wavelength renji, ndapota ona girafu rinotevera remareferensi ako.
