27mm Polished Glass Fiber Optic Lens
Fiber optic lens, 27mm diameter, used with minor shelf wear. Fiber lenses are exotic specialized devices made from a bundle of fiber optics fused into a solid mass. These devices are fascinating to experiment with; images are transfered and projected to the upper curvature of the lens, and are also useful for coupling vidicons or image intensifier tubes to other optical fixtures.
