A new instrumented baffle was installed in Spring 2021 at Virgo surrounding
the suspended mirror in the input mode cleaner triangular cavity. It serves as
a demonstrator of the technology designed to instrument the baffles in the main
arms in the near future. We present, for the first time, results on the
measured scattered light distribution inside the cavity as determined by the
new device using data collected between May and July 2021, with Virgo in
commissioning phase and operating with an input laser power in the cavity of
28.5~W. The sensitivity of the baffle is discussed and the data is compared to
scattered light simulations.
