Auxiliary Objective Lens for Stereo Zoom Microscopes This auxiliary objective lens expands the functionality of stereo zoom microscopes by changing the effective magnification and working distance. It is available in model options 0.5X, 0.7X, 1.0X, and 2.0X. The listing size is 0.7X. The lens is easy to mount and produces bright, clear images for inspection and observation tasks. Key benefits Flexible magnification control: choose 0.5X to halve your microscope's total magnification, 1.0X to maintain current magnification, 0.7X to reduce magnification to 70 percent, or 2.0X to double the total magnification. Alters working distance and focus length: auxiliary objectives reduce or increase the focus length as needed for different samples and setups. Simple installation: screwin mounting for quick attachment and removal without complex alignment. Improved image quality: designed to deliver bright and clear imaging for routine inspection tasks. Specifications Models available: 0.5X, 0.7X, 1.0X, 2.0X Listing size: 0.7X Magnification effect: 0.5X halves total magnification, 1.0X no change, 0.7X reduces magnification, 2.0X doubles total magnification Mounting thread: 48 mm Package contents: 1 x auxiliary objective lens Compatibility Designed as an accessory for stereo zoom microscopes. Verify the 48 mm mounting thread matches your microscope objective mount. Practical use scenarios Electronics inspection and : increase magnification for solder joint inspection or reduce magnification for larger board layout checks.
