Enhanced magnification options: Compatible with trinocular stereo zoom microscopes, this auxiliary lens provides versatile 0.5X, 0.7X, 1.0X, and 2.0X magnification choices to suit different observation needs and working distances. Wide compatibility and secure attachment: 48mm (17/8') mounting diameter fits most stereo zoom microscope models, ensuring secure attachment and optical alignment. Glass optics and durable construction: Crafted with quality glass elements and an ABS housing, this auxiliary lens delivers distortion images for detailed specimen examination and accurate documentation. Adjustable working distance: The 0.5X and 0.7X versions extend working distance to 120 mm and 165 mm respectively while reducing magnification, ideal for handling larger specimens or tools during observation. Practical applications: Electronics inspection and assembly: ideal for examining circuit boards, connectors, and fine solder joints with flexible magnification and improved working distance. Jewelry and small parts inspection: enables clear, distortion imaging of small components and surface defects. Laboratory documentation and measurement: suitable for observing larger specimens or using tools during measurement while maintaining image clarity.
