Spektromethara/Monochromator ea LGS-3 Modular Multifunctional Grating

Tlhaloso e Khutšoanyane:

Spektrometara ea grating ea liteko, e nang le detector ea PMT, mohlala o tsebahalang haholo.

Mesebetsi e mengata ea LGS-3 ModularSpectrometer ea Grating

Spektrometara ena e etselitsoe ho thusa baithuti ho utloisisa mehopolo ea liketsahalo tsa leseli le maqhubu le ho ithuta hore na spectrometara ea grating e sebetsa joang. Sebopeho sa modular se fana ka litharollo tse tenyetsehang bakeng sa litekanyo tsa spectral tlas'a photomultiplier (PMT). Hape ke sesebelisoa sa bohlokoa sa tlhahlobo bakeng sa lithuto le litlhaloso tsa li-filter tsa optical le mehloli ea leseli.

Mesebetsi

1. Utloisisa le ho tseba molao-motheo oa ts'ebetso le ts'ebeliso ea li-spectrometer

2. Tekanyo ea spectroscopy ea ho monya: e ka sekaseka sekala sa ho monya sa ntho e lekantsoeng (khase, mokelikeli, se tiileng)

3. Tekanyo ea spectrum ea mosi: ho lekanya litšobotsi tsa spectral tsa mohloli oa leseli o ntšang

4. Tekanyo ea Rydberg constant ho sebelisoa hydrogen spectroscopy, tekanyo ea litšobotsi tsa kutlo ea likarolo tse amohelang, le tekanyo ea chromaticity
