Light guide cables are essential for transmitting the light output of the light source to the viewing instrument. Fiberscopes, videoscopes and some rigid borescopes have integral light guides but most borescopes require a separate cable. Here, the user has a choice of light transmission media and length.

There are two types of light guide cable:

Fiber light guide cables (KFLG). These use glass fibers to transmit the illumination and are available in standard lengths of 1, 2.2, 3 and 5m (3.3, 7.2, 9.8 and 16.4’).

Liquid light guide cables (LLGC). Although less flexible than the glass fiber types, a brighter white light is emitted by use of a saline gel for the transmitting medium. Standard lengths are 1.8 and 3.0m (5.9 and 9.8’) however, other lengths are available including versions designed specifically for ultra-violet applications.

All light guide cables have Olympus/BSI-BSI style connectors and are directly compatible with all Olympus light sources. For occasions where a light source or instrument of different manufacture is in use, conversion adaptors are available. In addition, an extension adaptor to allow two cables to be connected in series is available to provide a longer length or to extend the integral cable of a fiberscope or videoscope.
