L12848-265
Mercury free and high output deep-UV light source
The L12848-265 is a mercury-free deep-UV light source that utilizes electron-
beam excitation emission. Its compact body contains a lamp and a power
supply, eliminating the need to design a housing and allowing easy assembly
into equipment.
