Les éclairage en champ sombre proposent un éclairage à faible angle efficace sur les zones ciblées et optimisent le contraste des caractéristiques de la surface, telles que les marques gravées ou gaufrées au laser ou les défauts de la surface. Les éclairages en champ sombre sont particulièrement adaptés aux applications telles que la lecture de symbologies avec marquage au laser et l’inspection des surfaces avec des contours géométriques.
Exemple d’éclairage :
Logo gaufré sur une surface en métal : l’éclairage à faible angle permet d’obtenir une image à contraste élevé.
