Excelitas Technologies - LED OTFI-0050 Fiber Light Engine Optics Module Excelitas' LED Fiber Optic Module has been designed for OEM fiber optic illumination applications. The LED Fiber Optic Module couples high-intensity white light into fiber optic light guides for a range of applications including microscopy, machine vision and inspection systems. The LED Fiber Optic Module, OTFI-005X Series, offers OEMs an LED-based optical solution that is energy-efficient and maintenance-free. The optical module offers a low-heat and low-voltage alternative to halogen and metal-halide lamp-based fiber optic illuminators. In contrast to halogen bulbs, the color temperature of LED light remains stable when the light is dimmed, resulting in a consistent visual appearance. The LED source is comprised of high-power white LEDs, optics to precisely couple light into fiber, and a heat sink. The module will accept fiber light guides ranging from 3 mm up to 20 mm in diameter. It is easily adaptable to a broad range of fiber light guides from different manufacturers. Please contact us for a comprehensive list of fiber light guide adapters. LED Module OTFI-0050, delivers a high-intensity, homogeneous spot from the distal end of a fiber light guide.
