Light Guide Bundle for Olympus GIF-HQ190 Gastroscope

► Brief Description

The Light Guide Bundle (Fiberoptic Light Guide) for the Olympus EVIS EXERA III GIF-HQ190 gastroscope is a vital internal component responsible for transmitting high-intensity illumination from the xenon light source (CLV-190) through the flexible insertion tube to the distal tip of the scope. It ensures bright, uniform lighting required for high-resolution imaging and advanced observation modes like Narrow Band Imaging (NBI).

► Features

• High-Efficiency Light Transmission: Conveys maximum luminous flux over long distances while minimizing light loss, ensuring the gastrointestinal tract is brightly lit.
• Uniform Illumination Distribution: Prevents hot spots or shadowing across the wide 140° field of view, supporting clear observation in both Normal Focus and Near Focus modes.
• NBI Optimization: Precision-engineered glass fibers are calibrated to transmit the specific wavelengths required for Narrow Band Imaging (NBI), enhancing mucosal microvasculature contrast.
• Flexibility & Durability: Designed to withstand repetitive angulation, twisting, and bending cycles within the insertion and bending sections without degrading optical throughput.

►FAQ

What are common signs that indicate a damaged or failing Light Guide Bundle?

• A: Common indicators include:

  • Dim or dark image display on the monitor even when the light source brightness is turned up.

  • Dark spots, shadowing, or uneven illumination across the field of view.

  • Broken individual glass fibers visible under magnification during routine maintenance or leak testing.

  • Complete loss of illumination at the distal tip.
