Four selectable magnification options: 0.5X, 0.7X, 1.0X, 2.0X for flexible observation across a wide range of tasks. Each lens delivers precise optical performance for detailed specimen examination. Wide compatibility: designed for trinocular and binocular stereo zoom microscopes. Standard 48 mm (1-7/8") mounting diameter fits most microscope models without additional adapters. Optimized working distances: the 0.5X and 0.7X auxiliary lenses increase working distance to 120 mm and 165 mm respectively while lowering magnification. This gives you more room to manipulate larger specimens or use tools under the microscope without losing image quality. Quality optics and durable construction: precision glass elements produce clear, low-distortion images. Rugged ABS housing maintains alignment and optical integrity through regular use in laboratory, industrial, or educational environments. Why this lens helps you get the job done More control: choosing the correct magnification for the task improves inspection speed and reduces the need for constant refocusing or repositioning. Better access: extended working distance on the 0.5X and 0.7X lenses makes it easier to handle components, perform dissections, or use measurement tools under observation. Broad compatibility: standard 48 mm mount reduces setup time and eliminates the need for extra adapters on most trinocular and binocular stereo microscopes. Typical applications Electronics inspection and repair: examine circuit boards, solder joints, and small components while retaining space for probes and rework tools. Biological dissection and sample preparation: observe and manipulate larger specimens with extended working distance and reliable detail. Quality control and assembly: inspect small parts, fittings, and finished products in manufacturing or lab settings with consistent, distortion-free imaging.
