Microscope Auxiliary Lens designed to expand magnification options while maintaining stable optical performance and long service life. Key benefits Extends the effective magnification range of compatible microscopes, allowing finer detail or wider field viewing without replacing the main objective. Quick and secure installation using the standard 17/8 inch 48 mm mounting thread for repeatable alignment and stable imaging. Durable aluminiumcopper alloy construction provides corrosion resistance and mechanical stability for consistent results over time. What makes it useful Multiple magnification options to match different tasks: 0.3X, 0.5X, 0.7X, 0.75X, 1X, 1.5X, 2.0X. Designed as an auxiliary lens to modify overall system magnification while preserving optical path quality. Compact, lightweight metal body that resists wear and supports frequent handling in workshop or lab environments. Compatibility and sizing Mounting thread: 17/8 inch 48 mm, compatible with microscopes and stereo microscopes that accept auxiliary lenses with this thread size. Model Number: Microscope Auxiliary Lens Model Number 2: 1X 1.5X 2X 0.3X 0.5X 0.7X 0.75X Color option listed as 0.3X; other magnification versions are available as specified. Typical applications Electronics inspection and : increase magnification for detailed solder joint and component inspection or reduce magnification for fullboard orientation checks. Precision assembly and jewelry work: adjust viewing scale to match the detail level required for fitting, polishing, or stone setting. Quality control and smallpart inspection: switch magnification to compare surface features, detect defects, or perform measurements. Performance and care Stable optical modification without the need to change primary optics for many tasks. Clean with a soft, lint cloth and appropriate lens cleaning fluid. Avoid abrasive materials and overt mechanical force when mounting or removing the lens. Technical specifications Material: Aluminiumcopper alloy Available magnification powers: 0.3X, 0.5X, 0.7X, 0.75X, 1X, 1.5X, 2.0X Mounting thread: 17/8 inch 48 mm This auxiliary lens provides a straightforward way to expand the flexibility of microscopes that accept a 17/8 inch 48 mm auxiliary lens thread while offering durable construction and multiple magnification choices.
