The Fiber Optic Illuminators are often referred to as "Cold Light" Illuminators because they provide high intensity, focused light without the heat typically associated with high intensity lamps. The common uses for the are: Microscopes and Video Microscopes Boroscopes, Industrial Imaging (Machine Vision), and Custom Process and Inspection Equipment (Wire Bonders, Laser Welding). Allows a uniform halogen illumination of focused white light which can be used in different applications. Included is an on/off intensity control which allows easy adjustment of intensity. In addition, the lock-in feature allows light guides to stay in place and permits the illuminator to operate on its back without fear of falling off. The arm length is 24" and has a 0.265" main fiber bundle diameter.
