Visionopen BioLab 4X — Laboratory Grade Desktop Magnifier

The Visionopen BioLab 4X is a laboratory-grade desktop magnifier constructed to a standard of mechanical precision and optical quality appropriate for research, quality assurance, and professional inspection environments where consumer-grade desk magnifiers are inadequate. The 110mm plan-corrected optical glass lens delivers 4x magnification with a flat field across the full lens diameter — plan correction eliminates the curvature of field that causes the center of the image to be in focus while the edges are soft, an artifact present in all non-plan-corrected lenses. For inspection of flat surfaces such as PCBs, fabric weaves, printed documents, and biological slides, plan correction ensures every point of the field is simultaneously sharp. The heavy-duty rack-and-pinion focusing column with 150mm travel and 0.5mm graduated scale allows precise and repeatable focus positioning. The 240mm × 180mm anti-static examination platform is suitable for electronic component inspection. Coarse and fine focus wheels. A ring of 20 high-CRI (CRI 98) LEDs provides research-grade illumination at selectable 4000K, 5500K, or 6500K color temperatures. Adjustable intensity via rotary encoder with digital display. USB-C powered. Weight: 2.1 kg.
