HAMAMATSU R6800U-01 Datasheet

Compact (16 mm diameter, 12 mm seated length),

solar blind (spectral response: 185 to 320 nm)

The R6800U-01 is a subminiature phototube encapsu­lated 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.
