The National Optical 452TBL & 453TBL Series delivers durable, high-clarity stereo imaging for STEM education, dissection labs, and industrial inspection in a portable cordless format. Built with LED illumination and a rugged cast-metal frame, these microscopes provide reliable 3D imaging performance in classrooms or field environments.
452TBL-10-LED (1X & 3X Magnification) – A compact 12-inch stereo microscope offering bright, upright, and unreversed viewing for natural sample observation. Its dual LED illumination (top/bottom) enhances depth and surface contrast, making it ideal for biology, entomology, and materials study. Perfect for elementary through high school programs needing portability and precision.
453TBL-10-LED (2X & 4X Magnification) – Designed for higher detail and resolution, this model includes achromatic, parfocal objectives and widefield 10X eyepieces for accurate 3D imaging. The 4-position light control system and 50-hour rechargeable LED power make it ideal for detailed biological, botanical, and material analysis in both classrooms and fieldwork.
Both models provide true-color images, ergonomic operation, and cordless convenience—combining educational simplicity with professional optical quality.
