SOLAR BLIND PHOTOTUBE
R6800U-26
Compact (16 mm diameter, 12 mm seated length),
solar blind (spectral response: 115 to 220 nm)
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.
