Dark Field Illuminators

Dark Field

Dark-Field Illuminators provide effective low-angle lighting to targeted regions. DF-Series machine vision lights use either a single tier of LEDs mounted at either 70º (DF-50) or 90º (DF-100-1 & DF-150-1) to the optical axis, or three tiers of LEDs mounted at 75º to the optical axis (DF-150-3). For machine vision applications with parts moving at high speeds (e.g. conveyors), strobe models are available to "stop" motion for the camera. .
