Kadena PMEL keeps PACOM’s calibrations precise
Staff Sgt. Sean Pentz, Component Maintenance Squadron precision measurement equipment laboratory technician, uses a line up sight telescope, an optical micrometer and an optical wedge to calibrate a multiple-target collimator on Kadena Air Base, Japan, Oct. 3, 2013. The collimator is used to calibrate surveillance equipment and can be used to replicate a target at infinity without distortion. (U.S. Air Force photo by Senior Airman Marcus Morris)
