UHR Laser Profilometry Equipment for 155mm M776 M284 cannon bore measurement

The U.S. Army Yuma Proving Ground seeks a ultra‑high‑resolution laser profilometry system for inspecting 155 mm cannon bore tubes (M776, M284A2). The contractor must supply a complete scanner assembly, a calibration ring, and ensure full compatibility with existing Video Bore Inspection System (VBIS) and Laser Bore Inspection System (LBIS) equipment. Critical specifications include adjustable axial/rotary scan resolution, sub‑0.01 mm accuracy, IEC Class 3R laser power < 5 mW, and a measurement range covering 152.43‑160.05 mm. • Deliver one UHR laser profilometry scanner assembly and one calibration ring. • Provide equipment that integrates with current VBIS/LVDT/LBIS hardware and supports 155 mm bore sizes. • Meet stringent measurement repeatability (≤ 0.012 mm) and accuracy (≤ 0.0005 in) requirements.
