Leica Plan 0.5x Stereo Microscope Objective

The Leica Plan 0.5x Auxiliary Objective (cat. no. 10446157) threads directly onto the front of Leica MZ and M series stereo microscopes via the M65 thread, transforming the working distance from the standard ~100mm range to a full 135mm — a critical advantage in any application where hands, instruments, or equipment must fit between the objective and the specimen. The 0.5x factor reduces the effective magnification across the full zoom range by half, simultaneously widening the field of view for a broader overview of the work area. The Plan optical correction maintains a flat, well-corrected image field, ensuring sharp detail from edge to edge even at the extended working distance. With a 66mm outer diameter and M65 thread, it is a direct OEM fit requiring no adapters. This listing is for a unit in excellent condition with flawless optics — an exceptional value for surgical, dissection, or industrial labs that need maximum working clearance from their Leica stereo system.
