Fostec A08630 Fiber Optic Light Ring Assembly

Fostec A08630 Fiber Optic Light Ring Assembly is a Schott ColdVision ring light designed for microscope objectives from 38 to 53 mm in diameter. The ring’s clear aperture measures 53.1 mm (2.09 in) across, with an outer ring diameter of 58.7 mm (2.31 in), allowing it to mount around standard objectives while not obstructing working distance. A 40-inch (1016 mm) lead carries illumination to a compatible light source, and the fiber bundle itself is typically 34 inches long, providing flexible placement in lab benches and imaging stations. The A08630 is compatible with SCHOTT ColdVision CV-LS and MC-LS light sources, enabling diffuse, shadow-free illumination around the objective for brightfield, darkfield, and contrast-enhanced imaging. This fiber-optic ring light is designed to produce even illumination around the lens, reducing shading artifacts that can occur with top-lit illuminators, and is suitable for applications such as specimen prep, material inspection, and high-contrast microscopy where uniform ring illumination around the objective improves feature visibility. Note that performance depends on the connected light source and diffuser configuration, and a compatible light-source box is typically required to operate the system.
