METAL PACKAGE SOLAR BLIND PHOTOTUBE R6800U-01 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.
