CE ÎNSEAMNĂ ELECTROSTATIC LENS ÎN ENGLEZĂ?
Lentile electrostatice
O lentilă electrostatică este un dispozitiv care ajută la transportul particulelor încărcate. De exemplu, poate orienta electronii emise dintr-o probă la un analizor de electroni, analog cu modul în care o lentilă optică ajută la transportul luminii într-un instrument optic. Sistemele de lentile electrostatice pot fi proiectate în același mod ca lentilele optice, astfel încât lentilele electrostatice ușurează ușor sau converg traiectoriile electronice. O lentilă electrostatică poate fi, de asemenea, utilizată pentru a focaliza un fascicul de ioni, de exemplu pentru a face un microbeam pentru iradierea celulelor individuale.
Definiția electrostatic lens în dicționarul Engleză
Definiția lentilelor electrostatice din dicționar este o lentilă electronică constând dintr-un sistem de electrozi metalici, câmpul electrostatic al căruia se concentrează particulele încărcate.
