Description
Fiber Optic Ring Light Guide 4-Port Flex Cable Microscope Illuminator 88mm OD
This fiber optic ring light guide is a flexible cable-based illuminator designed to deliver bright, even ring lighting around a microscope objective. The coiled flex cable carries light from an external source to the ring mount, where four evenly spaced ports distribute illumination around the inner circumference of the ring. The ring mounts around the objective or specimen stage of a stereo or inspection microscope to provide shadow-free, annular illumination. No light source or power supply is included.

Applications
Fiber optic ring light guides like this one are standard illumination accessories for stereo microscopes, inspection microscopes, and macro photography setups where even, shadow-free lighting is needed around the specimen. The ring format surrounds the objective, eliminating the directional shadows that a single-arm or overhead light source would cast, which is especially important when inspecting surface textures, circuit boards, small mechanical parts, or biological specimens. The flexible cable allows the input end to be positioned at any convenient angle relative to an external fiber optic illuminator or cold-light source. These guides are widely used in electronics inspection, quality control, biological dissection, gemology, and precision assembly work. The 88 mm outer diameter and 50 mm inner diameter are common dimensions for use with standard stereo microscope stands, though compatibility should be verified against the specific microscope model before purchase.
This fiber optic ring light guide has been inspected and is in good used condition. The ring mount and flex cable are intact with no cracks or breaks. The aluminum outer ring shows minor handling wear and there is some surface discoloration on the brass fitting at the cable-to-ring junction, as visible in the photos. All four light ports are present and unobstructed. No light source or power supply is included — the item was illuminated in the photos for display purposes only.
