The Binocular Biological Microscope is an excellent tool designed for school laboratories and science education. Equipped with achromatic objective lenses (4X, 10X, 40X, 100X oil immersion), it delivers sharp and detailed images suitable for a wide range of biological specimens. The hinged binocular observation head is ergonomically tilted at 45° to minimize eye and neck fatigue during prolonged viewing sessions. Its double-layer movable stage measures 140×140mm with a 75×45mm moving range, enabling precise and smooth sample positioning. The coaxial coarse and fine focusing mechanism features a 30mm focusing range and a fine adjustment scale value of 0.002mm for accurate focusing. Illumination is provided by a powerful 20W halogen lamp with an NA=1.25 Abbe condenser, iris diaphragm, and color filters, offering bright and adjustable lighting suitable for transparent and opaque specimens. Ideal for students and educators, this microscope supports hands-on learning and scientific discovery.
