HDD Inspection with SI Series and LJ-V Series Laser Measurement Systems

This document details advanced optical measurement technologies for inspecting hard disk drive components, including glass media thickness, displacement between medium and motor, base plate flatness, and cover case sealant height. It highlights the SI Series spectral-interference laser displacement meter and the LJ-V Series high-speed 2D/3D laser scanner, emphasizing their non-contact, high-accuracy, and high-speed capabilities that overcome limitations of conventional capacitive sensing and contact methods.
