0.5x reduction objective lens for a stereo microscope that expands the field of view and increases working distance to 165 mm. This allows more space to manipulate samples while preserving clear viewing of details. Easy to install: simply screw the lens onto the objective. It uses a standard 48 mm (7-7/8 inch) mounting thread. Durable and reliable: made from high quality materials to ensure long term stability and performance under regular use. Compatibility and design: suitable for standard stereo microscope setups that require a 48 mm threaded objective, ensuring broad compatibility with common accessories. Applications and scenarios: - Electronics inspection and repair: view traces and components on PC boards with more room to maneuver probes and tools. - Small parts inspection and assembly: inspect fine features and fit tolerances, while having extra working space for handling parts. - Education and specimen observation: demonstrate and observe larger specimens or educational models with an expanded field of view and ample working space.
