Leica B-290 Trinocular Brightfield Microscope with 1000x Magnification and PLAN Objectives

The Leica B-290 Trinocular Brightfield Microscope is engineered for precision imaging in biotechnology, molecular diagnostics, and cell biology research. Featuring a trinocular head with a fixed 50/50 light split, 360° rotation, and 30° inclination, it supports advanced fluorescence analysis and live-cell imaging workflows.

Key technical specifications include:

• Observation Mode: Brightfield imaging optimized for high-resolution optical microscopy.
• Optical System: PLAN objectives configured for high numerical aperture and anti-fungal treatment: 4x/0.10, 10x/0.25, 40x/0.65, and 100x/1.25 (Oil/Water) enabling up to 1000x magnification critical for bioprocessing and molecular cloning visualization.
• Eyepieces: Widefield 10x/20 mm with dioptric adjustments and secure fitting to ensure ergonomic observation during extended microscopy sessions.
• Stage: Double-layer, rackless mechanical sliding stage (150x139 mm) with precise X-Y movement (75x33 mm range) and 0.1 mm Vernier scale accuracy, essential for reproducible sample positioning in synthetic biology research.
• Focusing Mechanism: Coaxial coarse and fine focus with adjustable tension and limit stop to prevent objective-specimen contact, supporting delicate specimen handling in clinical diagnostics.
• Condenser: Abbe condenser with N.A. 1.25, objective-coded iris diaphragm, focusable and centerable to optimize light contrast and resolution for fluorescence and brightfield applications.
• Illumination: Fixed Koehler illumination system with X-LED3 white LED, 3.6 W, 6300 K color temperature, and adjustable intensity, powered by a multi-plug external supply (100-240 Vac/6 Vdc), ensuring consistent light conditions critical in biomanufacturing quality control.

This microscope is widely used in biomedical engineering labs and biotechnology facilities for applications such as gene editing assessment, live-cell morphology studies, and fluorescence-based fluorescence analysis, making it a reliable instrument for molecular biology researchers and clinical scientists.
