0.5X Extended WD Stereo Microscope Barlow Lens

A dedicated 0.5X auxiliary objective lens with M48 thread interface and 165 mm working distance, built for stereo microscopes requiring expanded field coverage and ergonomic sample interaction. Physical specifications include a compact cylindrical form factor, hardened anodised aluminium barrel, and fully coated optical glass elements. Total length is approximately 42 mm; weight is 85 g. Compatible only with stereo microscopes equipped with M48 female threading on the objective nosepiece or adapter ring. Functionally, this lens reduces overall magnification by half while proportionally increasing field width and depth of field — improving context awareness during macro-level analysis. The fixed 165 mm working distance remains constant regardless of zoom setting, enabling consistent lighting setup and tool clearance. Used across university biology departments, electronics repair workshops, and vocational training centres where visual fidelity, repeatability, and physical accessibility are prioritised over ultra-high magnification.
