LED-optical fiber coupling PerkinElmer Optoelectronics

PerkinElmer’s new Fiber Optic Module has been designed for OEM fiber illumination applications. The module uses an LED light source designed to couple high intensity white light into fiber optic bundles for applications including medical endoscopy,microscopy and machine vision. It offers an energy-efficient, maintenance-free alternative to halogen-based and metal-halide fiber optic illuminators. The LED source is comprised of high power white LEDs, patent-pending optics to precisely couple light into fiber and a heat sink. It has been designed to couple light into 3-10 mm fiber; the light is easily adaptable to a broad range of fiber manufacturers and sizes. Light intensity control electronics are available as an option.

The LED light module delivers a high intensity homogenous spot from the distal end of the fiber bundle. The new module offers a low heat, and low voltage alternative to 150-Watt halogen-based fiber illuminators. In contrast to halogen bulbs, the color temperature of LED light does not change when the light is dimmed or as the bulb ages, resulting in a consistent visual appearance.
