The outer diameter, needle tip height and coaxiality of the syringe needle are directly related to injection safety and comfort. Traditional visual inspection has insufficient stability on reflective metal surfaces and is insensitive to small height changes.
LightE introduces a chromatic confocal displacement sensor to measure the key geometric dimensions of the needle with high precision. Spectral confocal technology has strong adaptability to metal highly reflective surfaces and can stably obtain height and profile data on high-speed production lines to achieve full inspection or high-proportion sampling inspection.
