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

The B-190 Monocular Brightfield Microscope is engineered for educational and secondary school laboratory environments, providing advanced optical performance with a finite optical system and 600x maximum magnification using four N-PLAN objectives. This optical microscope features a monocular head, 360° rotation, and 30° inclination for ergonomic observation. It employs a quadruple revolving nosepiece with ball bearing rotation for precise objective switching.

Key technical specifications include:

• Optics: Four N-PLAN objectives (4x/0.10, 10x/0.25, 40x/0.65, 60x/0.85) with anti-fungus treatment, enabling clear, detailed imaging essential for cell morphology studies and educational microscopy.
• Eyepiece: Widefield WF 10x/18mm ensuring high eyepoint observation for comfort during extended use.
• Stage: Double-layer mechanical sliding specimen stage measuring 125×115 mm with 70×30 mm X-Y movement and 0.1 mm Vernier scale accuracy, supporting reproducible sample positioning in microscopic analysis and biotechnology workflows.
• Focusing: Coaxial coarse and fine focus with adjustable tension and a limit stop to protect objectives and specimens, critical for delicate sample handling in molecular diagnostics and synthetic biology research.
• Condenser: Pre-centered Abbe condenser with NA 1.25 and iris diaphragm allowing optimal illumination control for brightfield contrast enhancement.
• Illumination: Energy-efficient X-LED² light source with 3 W white LED and adjustable intensity control, delivering uniform 6,300 K color temperature lighting designed for stable, long-term microscopy without heat generation.

Powered by a multi-plug 100-240Vac/6Vdc external power supply, this microscope is slim, portable, and durable with over 20 years lifespan LED illumination, making it widely adopted in biotechnology education, clinical diagnostics training, and biomedical engineering teaching labs. Its robust features and precise optics make it essential for live-cell imaging preparation, tissue sample examination, and histology workflows in research and academic settings.
