How do fiber optic light guides connect to fiber optic illuminators?

An adapter is required to connect our Fiber Optic Light Guides to our Fiber Optic Illuminators which all have a standard 25mm diameter opening port. Our Light Guide Adapters are metallic bushings with a ring shape designed to fit in the open aperture of our various illuminators. The light guide is inserted into the center hole of the adapter. The adapter and light guide are then held within the illuminator's aperture by a set screw. To select the correct adapter, you must match up the inner diameter of the adapter and the end-tip diameter of the light guide.
