Iluminadores de campo oscuro proporcionan una iluminación de bajo ángulo efectivo de las regiones seleccionadas. Estas luces de visión artificial mejoran el contraste de características de la superficie, tales como marcas de láser o grabado en relieve o defectos de superficie, y son particularmente adecuadas para aplicaciones tales como la colocación de BGA bola, leer simbologías de grabado con láser y la inspección de las superficies con contornos geométrico.
Iluminadores de campo oscuro utilizan ya sea un único nivel de LEDs montados en cualquiera de 70º (50 modelos DF) o 90º (DF 100, DF 150-1 modelos) al eje óptico, o tres niveles de LEDs montados a 75º con el eje óptico (DF 150-3 modelos).
Ejemplo de iluminación:
Logotipo en relieve sobre una superficie de metal: la iluminación de ángulo inferior proporciona una imagen de alto contraste
