Leica 0.5x C-Mount for 37mm Port

The Leica 0.5x C-Mount Adapter (cat. no. 541016) is the OEM solution for coupling C-mount cameras to Leica stereo microscopes equipped with a 37mm photo port. The integrated 0.5x reduction lens is the critical optical element: it reduces the projected image circle to match the smaller sensor sizes common in scientific and industrial C-mount cameras (1/2”, 1/3”, 2/3”), preventing vignetting and ensuring the camera captures the full, usable field of view. Without a reduction lens, C-mount cameras on stereo microscopes typically show a heavily vignetted image with only the center of the field visible. The 37mm insert fits directly into Leica MZ and M series photo ports, and the C-mount output accepts any standard C-mount camera body. As a genuine Leica OEM component, it maintains optical quality throughout the imaging path. This listing is for a unit in excellent condition — a practical, cost-effective upgrade for any Leica stereo system being configured for digital imaging.
