Fostec Schott A21040 Calibrated Fiber Optic Light Guide

The Fostec Schott A21040 Dual Randomized Calibrated Fiber Optic Light Guide is a 48-inch (1219 mm) dual-bundle illumination tool designed for SCHOTT ColdVision systems, delivering calibrated output through two randomized fiber paths. It features an active input fiber diameter of 0.36 inches (9 mm), a tubing diameter of 0.60 inches (15 mm), a distal ferrule diameter of 0.393 inches (10 mm), and a bend radius of 1.0 inch (25 mm). The 48-inch bundle length provides ample reach from the light source to the target area, enabling flexible routing in compact setups while maintaining consistent illumination across the field. Commonly used in microscopy and inspection workflows that require bright, steady illumination, this light guide is designed for use with SCHOTT ColdVision light sources and is compatible with existing Fostec light guide configurations. The A21040 designation identifies these dual randomized calibrated bundles as part of SCHOTT's ColdVision lineup, enabling reliable integration into microscopy stages or inspection benches.
