Experience professional-grade clarity and precision with the National Optical 420T Zoom Stereo Microscope (1X–4X Zoom, 10X–40X Magnification). Designed for laboratories, classrooms, and industrial inspection, this trinocular stereo microscope delivers exceptional image quality, ergonomic design, and reliable performance.
Its zoom range from 1X to 4X allows continuous magnification from 10X to 40X, providing versatility for observing specimens of all sizes — from circuit boards and plant samples to biological tissues and gemstones. The upright, unreversed 3D image stays sharp and in focus throughout the zoom range, ensuring seamless transitions without constant refocusing.
The trinocular head enables easy integration with digital cameras or video systems for image capture, documentation, and classroom demonstrations. Equipped with dual LED illumination (top and bottom), this model provides bright, cool, energy-efficient lighting for both reflective and transmitted observation.
Built with a durable all-metal frame and adjustable post stand, it accommodates large or tall specimens with stability and precision. Whether used for teaching, quality control, or research applications, the National 420T-430PLL-10 sets the standard for dependable zoom stereo microscopy.
