  Pohang Light Source-II (PLS-II) is recently upgraded to 3 GeV and the circumference, beam current, emittance of PLS-II storage ring are 281.82 m, 100 mA and 5.7 nm-rad, respectively. The storage ring includes an interferometry beam size monitor system in 2B beam line. It consists of the quadrature slit, lens, 650 nm wave-length filter and CCD camera. We will present the measurement results and the issues to optimize the beam size monitor system in the beam line.
