B-190 Binocular Brightfield Microscope with 600x Magnification and PLAN Objectives

The B-190 Binocular Brightfield Microscope is an advanced optical instrument optimized for detailed specimen observation in educational, biomedical, and biotechnology research settings. It features a binocular head with 360° rotation and 30° inclination, enabling ergonomic viewing with interpupillary distance adjustable from 48 to 75 mm and dioptric correction on the left eyepiece.

Key optical components include four N-PLAN objectives (4x/0.10, 10x/0.25, 40x/0.65, 60x/0.85) with anti-fungus treatment, delivering a total magnification of up to 600x. These objectives are mounted on a quadruple revolving nosepiece with smooth ball-bearing rotation for efficient switching during microscopy workflows.

The microscope employs a finite optical system with wide field (WF) 10x/18 mm eyepieces to enhance field of view and resolution. The mechanical stage offers double-layer sliding capabilities with precise X-Y control (125 x 115 mm stage size, 70 x 30 mm movement range), accompanied by a Vernier scale with 0.1 mm accuracy, essential for meticulous sample positioning in live-cell imaging or molecular diagnostics.

Focusing is controlled via coaxial coarse and fine focus knobs with adjustable tension and a built-in limit stop to protect objectives and specimens, supporting reliable imaging in synthetic biology and bioprocessing applications.

Illumination is provided by a 3 W X-LED² white LED light source with 6,300 K color temperature and adjustable intensity, ensuring uniform, high-contrast brightfield visualization critical for fluorescence analysis and histology. The integrated Abbe condenser with numerical aperture of 1.25 and iris diaphragm is height-adjustable to maximize contrast and resolution in diverse sample types.

Designed for durability and portability, the B-190 is a practical choice for secondary education, biotechnology laboratories, and clinical diagnostics, widely adopted in molecular biology and biopharmaceutical production pipelines where precise and stable microscope imaging is essential. The long-lasting LED illumination system guarantees over 20 years of operational lifespan, supporting sustainable biomanufacturing quality control workflows.
