Advanced Illumination High Intensity Large Area Diffuse LED Illuminators are ideal for factory automation and the large scale inspection of large metallic objects and other reflective parts. These illuminators are constructed of a rugged metal design and can provide a diffuse, even illumination of an 18" x 18" area. The strobed models' flash duration is dependent on a trigger signal or potentiometer setting. The duration of the strobe can be adjusted from 30 - 300μs via a knob located in the back of the unit. The trigger input signal of the Advanced Illumination High Intensity Large Area Diffuse LED Illuminator is CMOS/TTL compatible. The maximum trigger frequency is 30 Hz.
