APPLICATIONS
l Ar2: 126nm l F2 : 157nm n Excimer Lamp Monitor n UV Power Meter The R6800U-26 is a subminiature phototube encapsu- lated in a TO-8 metal package. The electrode structure is designed to operate at a low voltage, allowing easy handling. Its excellent solar-blind spectral response ensures efficient UV detection without using an optical visible cut filter. PRELIMINARY DATA AUG. 1999
