We have directly observed charge density modulation in the optimally doped Bi2201 at momentum transfer $Q_{\\|} \\simeq 0.23$ rlu, with smaller intensity and correlation length with respect to the underdoped sample. This demonstrates that short-range charge order in Bi2201 persists up to optimal doping, as in other hole-doped cuprates.
