This Binocular Research Microscope is a reliable, high-performance optical instrument designed for intensive use in medical, educational, and research laboratories. Engineered for comfort and precision, it features a 360-degree rotatable binocular head inclined at an ergonomic angle to minimize user fatigue during long observation sessions. The "Basic" research series provides essential high-grade features including a quadruple revolving nosepiece and a precision mechanical stage, making it an ideal choice for microbiology, pathology, and general biological studies. Key Features & Benefits: Advanced Optical System: Equipped with high-quality wide-field 10x eyepieces and a suite of four achromatic objectives (4x, 10x, 40x Spring, and 100x Oil Immersion Spring), providing a total magnification range of 40x to 1000x. Precision Focusing: Features a coaxial coarse and fine focusing mechanism for smooth, high-precision adjustment, essential for viewing fine cellular details at high magnifications. Sturdy Ergonomic Design: Built on a robust, vibration-resistant base with an inclined head that allows for easy interpupillary and dioptric adjustments to suit multiple users. Versatile Illumination: typically integrated with a high-intensity LED illumination system (or 6V 20W Halogen) with adjustable brightness control, ensuring uniform light distribution across the field of view. Professional Mechanical Stage: Large, double-layer mechanical stage with low-position coaxial controls for precise X-Y specimen manipulation. Quality Condenser: Includes a sub-stage Abbe Condenser (N.A. 1.25) with an iris diaphragm and filter holder to optimize light contrast and resolution.
