Answering the needs of coaxial illumination, the N3C-A provides such a solution mainly for using with TL (long-working distance) models of Dino-Lite Edge series. The coaxial front light, formed by mirroring the light of Dino-Lite with a beam splitter, helps to highlight scratches and dents from reflective surface, or to avoid shadow obscured by thick surroundings of deep holes. The compact and interchangeable N3C-A is an ideal supplement for tackling with inspection challenges.
