Ukuphepha Kwenzwa Yebanga Le-Laser

Ukuthuthukiswa okusheshayo kobuchwepheshe be-laser kuye kwaholela ekusungulweni kwezobuchwepheshe emkhakheni weinzwa yebanga le-laser. Inzwa ye-laser ehlukahlukene isebenzisa i-laser njengento esemqoka yokusebenza. Okwamanje, mainukulinganisa laserizinto ezisemakethe yilezi: ubude begagasi obusebenzayo be-905nm kanye ne-1540nm semiconductor laser kanye nobude obusebenzayo be-wavelength engu-1064nm YAG. Uyini umthetho wamazwe ngamazwe mayelana nokuphepha kwemishini ye-laser? I-Food and Drug Administration (i-FDA) ihlukanisa amadivayisi e-laser abe amakilasi ayisithupha ngokususelwe kusayizi wokuphuma kwe-laser: IkilasiⅠ, Ikilasi ⅱA, IkilasiⅡ, IkilasiⅢa, IkilasiⅢb kanye NekilasiⅣ.

Ikilasi I: I-laser engabonakali ekhiphayo ephansi (amandla angaphansi kuka-0.4mW) ayidluli inani le-MPE lamehlo nesikhumba ngaphansi kwanoma yisiphi isimo, ngisho nangemva kokugxila ohlelweni lokubona. Ingaqinisekisa ukuphepha komklamo, ngaphandle kokuphathwa okukhethekile. Izicelo ezijwayelekile zifaka Izikhombi ze-laser, izidlali ze-CD, okokusebenza kwe-CD-ROM, okokusebenza kokuhlola umhlaba kanye namathuluzi okuhlaziya elabhorethri.

I-Class II: I-laser ebonakalayo ephumayo ephansi (amandla angu-0.4mW-1mW), isikhathi sokusabela sokuvalwa kweso singamasekhondi angu-0.25, ukusebenzisa lesi sikhathi ukubala ukuchayeka akukwazi ukudlula inani le-MPE. Ngokuvamile, i-laser engaphansi kuka-1mW izobangela isiyezi futhi ingakwazi ukucabanga. Ngeke kushiwo ukuthi kuphephe ngokuphelele ukuvala amehlo ukuze uvikeleke. Ngakho-ke, ungabheki ngqo emgqeni, ungasebenzisi i-laser ye-Class II ukukhanyisa amehlo abanye abantu ngokuqondile, futhi ugweme ukubuka i-laser ye-Class II ngemishini yokubona kude. Izicelo ezijwayelekile zifaka imiboniso yasekilasini, Izikhombi ze-laser, okokusebenza kokubona kanyerangefinders.

Zimbili kuphela izinhlobo zamalaser ezibaluliwe lapha ngenxa ye-Seakeda'sinzwa esukelaimikhiqizo ikakhulukazi isebenzisa i-laser Class I kanye neClass II njengezinto zokusebenza. I-laser wavelength ingu-620~690nm namandla angu-<0.4mW kanye no-<1mW. Ukuphepha kwayo okuphezulu, ukusebenza kahle, ukonga amandla okwengeziwe. Ngakho ungakhetha ngokuphepha yethuinzwa yobubanzi be-laser.
