System for inspecting a defect of polarizing film

A system for inspecting defects of a polarization film is provided to inspect detects in a low resolution and the defects in a higher resolution using a defect inspector for more accurate inspection. A system for inspecting defects of a polarization film includes a loading unit(200), a speed detector(300), an inspection unit, a marking unit(500), an unloading unit(600), and a controller(700). The loading unit loads the polarization film wound on a winding roller(220). The speed detector detects speed of moving polarization film. The inspection unit is installed on a main frame(100) and photographs the polarization film with first and second cameras(430,470). The marking unit marks defects on the polarization film. The unloading unit unloads the polarization film with an unloading roller. The controller calculates positions of the defects for accurately marking the defects and receives the speed of the polarization film for synchronizing speeds of photographing and marking.
