This Biological Binocular Microscope is an excellent educational tool designed for children and students to explore the microscopic world. Featuring achromatic objective lenses of 4X, 10X, 40X, and 100X oil immersion, it delivers crisp, detailed images suitable for a wide range of biological samples. The large field of view WF10X eyepieces ensure comfortable viewing, with an option to upgrade to WF16X. The binocular head is tilted at 45° and translational for ergonomic use, reducing fatigue during long observation sessions. A double-layer movable stage (140x140mm) with 75x45mm travel allows precise sample manipulation. The coaxial coarse and fine focusing mechanism offers a focusing range of 30mm and a fine adjustment scale of 0.002mm for ultimate clarity. Bright and adjustable illumination is provided by a 20W halogen lamp with a condenser NA=1.25, variable diaphragm, and color filters to enhance contrast. Ideal for school laboratories and science education, this microscope supports hands-on learning and discovery.
