Product Description
The BS‑2025 Series Biological Microscopes from BestScope combine advanced machining technology, ergonomic design, and reliable LED illumination—delivering clear, stable images for educational and clinical applications. Designed for teaching, clinical verification, and routine laboratory work, these microscopes feature a finite optical system with high‑quality achromatic objectives (4×, 10×, 40×, 100× oil) and a quadruple nosepiece for easy magnification changes.
Three models are available: BS‑2025M (monocular), BS‑2025B (binocular), and BS‑2025T (trinocular). All feature Seidentopf viewing heads inclined at 30° with 360° rotation, and the binocular/trinocular versions offer adjustable interpupillary distance (48‑75mm) for comfortable viewing. The trinocular model includes a 20:80 light distribution and is ready for camera attachment via an adjustable 0.5× C‑mount adapter (included).
A robust double‑layer mechanical stage (125×115mm / 75×35mm) provides smooth, precise slide positioning, while coaxial coarse and fine focusing (0.002mm fine division) ensures sharp focusing. Illumination is provided by a 3W LED with adjustable brightness (standard), with optional rechargeable battery‑powered LED or 12V/20W halogen lamp for added flexibility. The BS‑2025 series is ideal for schools, clinics, hospitals, and research labs seeking a versatile, ergonomic microscope.
