POL-02 Polariscope is an inevitable tool in optical fiber production, enabling analysis of core preforms prior to sleeving, finished sleeved preforms or quartz tubes / rods. It is used to detect bubbles, inclusions, cracks, strain regions and other defects in glass structure. Light source and view lens assembly can slide freely along the preform length and permit observation of deposition pattern or inclusions. Defect position is read from the sliding rule at pointer tip.
