Techniquip FOI-1 Fiber Optic Light Source Illuminator

The Techniquip FOI-1 Fiber Optic Light Source Illuminator is a 150 W quartz halogen fiber-optic illuminator that delivers high-intensity, shadow-free illumination through a 5/8 in standard fiber optic port with electronic variable intensity control for precise brightness adjustments. Built for industrial and scientific imaging, it supports stereo microscopes, machine vision systems, semiconductor inspection equipment, video inspection stations, metrology, laboratory instruments, and OEM optical gear, while keeping heat at the work surface minimal. The unit uses forced-air cooling with a ball bearing fan and offers 110 VAC or 220 VAC input (model dependent) at 50/60 Hz. Key safety and reliability features include dual fuse protection, over-temperature protection, and an IR/UV reflective filter, all housed in a powder-coated metal enclosure measuring about 7.0 × 7.5 × 6.5 in and weighing roughly 7.5 lb. It is compatible with fiber optic light guides, stereo microscopes, machine vision systems, and optical inspection equipment, and is commonly used for repair, replacement, retrofit, and preventive maintenance; common replacements include FOI-150, FOI-250, and ProLux LED illuminators.
