The Scienscope FC-DP-18 is a dual pipe fiber optic light guide. It features an 18 inch fiber optic cable, and is ideal for precision lighting and transmission. With a bendable neck, the light can be positioned exactly where it is needed, providing a high degree of adjustable illumination. Please note, this must be connected to an external illuminator, such as the Scienscope IL-FOI-L24A LED systems, or the IL-FOI-150 Halogen.
