Imishini ye-LADP-15 Yokunquma i-Constant kaPlanck (Isofthiwe Ongakukhetha)

Ukuhlolwa

1、Linganisa i-voltage enqunyiwe bese ubala ukuze uthole i-constant kaPlanck.
2. Linganisa i-photocurrent ye-phototube bese uqhuba ukuhlolwa komphumela we-photoelectric.

Amapharamitha obuchwepheshe ayinhloko
1, ububanzi be-microcurrent: 10-6 ~ 10-13A inani lamafayela ayisithupha, isibonisi sedijithali ezintathu nengxenye, ukuzulazula okungu-zero ≤ amagama ama-2 / min.
2, uma ujikelezisa i-diaphragm, ngeke ishayele isihlungi sombala, lokhu kokubili kungajikeleziswa ngokuzimela, kungabi namthelela komunye nomunye, kuzwakale kulula, kulula ukukusebenzisa, futhi kugwenywe ukukhanya okuqondile kwe-phototube.
3, i-photocell: ibekwe ebhokisini elimnyama le-photocell, ububanzi bamandla okusebenza: -2V ~ +2V; -2V ~ +30V
amafayela amabili, anokulungiswa okuhle; ukuzinza ≤ 0.1%.
4, ububanzi bempendulo ye-spectral ye-phototube: 340 ~ 700nm, ukuzwela kwe-cathode ≥ 1μA, ugesi omnyama <2 × 10-12A, i-anode: indandatho ye-nickel.
5, isihlungi sombala: 365.0nm; 404.7nm; 435.8nm; 546.1nm; 578.0nm.
6, okuhlanganisa isibani se-mercury esinomfutho ophezulu kanye nokunikezwa kwamandla esibani se-mercury, amandla esibani se-mercury angu-50W.
7, iphutha lenani le-h kanye nenani lethiyori: ≤ 3%.
8, uhlobo lwekhompyutha encane lungaxhunywa nge-USB interface kwikhompyutha ukuze kwenziwe izivivinyo, ngaphandle kwekhompyutha.
