The 980nm semiconductor laser module is a near-infrared light source featuring excellent beam quality, low heat generation, high concealment and enhanced eye safety. It serves as a core light source widely used in industrial sensing, intelligent equipment, scientific detection and security night vision systems.
A speckle structured light laser is an integrated laser module composed of laser chip, driving circuit and DOE (Diffractive Optical Element). It diffracts single laser beam into millions of fixed, pseudo-random speckle dots via special DOE optics and projects unique granular speckle patterns onto target surfaces.
3D printing defect detection is a quality control procedure to find abnormal flaws during or after additive manufacturing, aiming to eliminate unqualified parts caused by layer shifting, missing printing, air pores, surface pits, warpage, unfused powder and dimensional deviation.
