LADP-15 Apparatus rau Kev Txiav Txim Planck's Constant (Software Optional)

Kev sim

1, Ntsuas qhov txiav tawm voltage thiab xam kom tau Planck qhov tsis tu ncua.
2, Ntsuas lub photocurrent ntawm lub phototube thiab ua qhov kev sim ntawm cov nyhuv photoelectric.

Main technical parameters
1, microcurrent ntau yam: 10-6 ~ 10-13A tag nrho ntawm rau cov ntaub ntawv, peb thiab ib nrab ntawm cov duab, xoom drift ≤ 2 lo lus / min.
2, thaum tig lub diaphragm, yuav tsis tsav cov xim lim, ob leeg tuaj yeem tig ntawm nws tus kheej, tsis muaj kev cuam tshuam rau ib leeg, hnov ​​lub teeb, siv tau yooj yim, thiab zam lub teeb ncaj qha phototube.
3, photocell: muab tso rau hauv lub thawv tsaus nti photocell, ua haujlwm lub zog ntau: -2V ~ + 2V;-2V ~ + 30V
ob cov ntaub ntawv, nrog zoo tu;stability ≤ 0.1%.
4, phototube spectral teb ntau: 340 ~ 700nm, cathode rhiab heev ≥ 1μA, tsaus nti tam sim no <2 × 10-12A, anode: nickel nplhaib.
5, xim lim: 365.0nm;404,7nm ;ua.435,8nm ;ua.546.1nm ;ua.5 78,0nm.
6, suav nrog kev kub siab mercury teeb thiab mercury teeb fais fab mov, mercury teeb lub zog 50W.
7, qhov yuam kev ntawm h tus nqi thiab tus nqi theoretical: ≤ 3%.
8, hom microcomputer tuaj yeem txuas nrog USB interface rau lub computer rau kev sim, tsis muaj computer.
