Compatible with trinocular microscopes This auxiliary lens is designed for Trinocular Binocular Stereo Zoom Microscopes and provides multiple magnification options: 5X, 0.7X, 1.0X, and 2.0X for a range of tasks. Maintains working distance The 0X configuration preserves the original working distance and protects your primary lenses from damage during use. Higher magnification at close range Using the 0X lens enables higher magnification at a shorter distance of 30 mm, allowing detailed analysis where close focus is required. Easy installation and solid compatibility Standard mounting size is 1 7/8 inches (48 mm), making this lens compatible with most stereo microscopes and straightforward to install. Practical use scenarios Electronics inspection: examine PCB solder joints, connectors, and micro components for defects. Precision components quality control: inspect gears, housings, and assemblies for tolerances and wear. Biological or material samples: observe tiny specimens or material features at enhanced magnification.
