Description
Leica 10446180 M-Series Coaxial Incandescent Light Source Fiber Optic Ring
The Leica 10446180 is a coaxial incandescent ring illuminator designed for use with Leica M-series stereo microscopes. It delivers coaxial (on-axis) illumination through a flexible fiber optic arm, directing light uniformly into the optical path for glare-free imaging of reflective or flat specimens. A 1.5x magnification factor is marked on the body. The unit mounts directly to compatible M-series microscope ports via its dual-port ring interface.

Applications
Coaxial illuminators like the Leica 10446180 are standard accessories for stereo microscopes used in electronics inspection, semiconductor and PCB analysis, gemology, watchmaking, biological dissection, and industrial quality control. Coaxial illumination is particularly valuable when examining flat, polished, or highly reflective surfaces — it eliminates the shadowing and glare that oblique lighting produces on such specimens, making surface defects, solder joints, and fine detail much easier to resolve. Leica's M-series stereo microscopes have been widely used in research, production, and clinical labs since the 1960s, and accessories like this ring light source remain in active use wherever an M-series microscope is in service. The flexible fiber optic arm allows the light source to be positioned or routed conveniently without constraining the microscope's working distance.
This Leica 10446180 M-Series Coaxial Incandescent Light Source has been inspected and appears to be in good used condition. The housing shows light surface wear consistent with normal lab use. The flexible fiber optic arm is intact, and both output ports are present and undamaged — the upper port measures approximately 57 mm in diameter and the lower port approximately 52 mm (45 mm at its narrowest point). The unit was pulled from a working environment where it was previously in service. Please review all photos and contact us with any questions before purchasing.
