Fiber Optic Light Guides are used to transmit illumination provided by fiber optic illuminators for a number of imaging or microscopy applications. Fiber Optic Light Guides interface with illuminators to transfer light to one of several adapter heads that transmit light in a usable manner. Fiber Optic Light Guides are available in several varieties including backlights or ring lights. Fiber Optic Light Guides offer the benefits of numerous illumination products with only one light source making them cheap, effective alternatives to many other illuminators.
Types of Light Guides
There are three basic types of light guides:

Liquid - Liquid light guides have a flexible outer sheath and a light-conducting liquid core. They are sealed with quartz windows that can be made transparent to a range of wavelengths.Fiber optic - A fiber optic light guide consists of a non-coherent bundle of optical fibers. The fibers at each end of the bundle are tightly compressed, cut perpendicular to the axis of the fibers, and polished to permiLight Guides imaget light to pass into and out of the bundle.LED - An LED light guide is used to guide light from light emitting diodes (LEDs) to a specific location. LED light pipes come in multiple colors, and are often used to connect panel indicators to their LED light source.
