1. Akukho ntsalela kuyo yonke le ndawo, i-RFU <5;
2. Ukubetha okuphezulu kokusebenza: Ngokweenkqubo ezahlukeneyo zokuphuma kunye nokulungiswa kwe-laser, ukubetha kunokuba ngaphakathi kwemizuzwana eyi-0.5;
3. Zonke izinto ezibonakalayo ziyilelwe ngokuzimeleyo, zigqityiwe kwaye zihlanganisene, kwaye inkqubo enguRhwebo enguRhwebo isebenza ngokuzimeleyo;
I-4. I-Laser optics kunye nezisombululo zenkqubo zinokwenziwa ngokulula ngokweemfuno ezahlukeneyo zabathengi
