The Magnus Mx21i Binocular LED Microscope is a robust, ergonomically designed optical instrument built for precision imaging, educational durability, and long-term reliability.
Equipped with infinity-corrected plan optics, a rackless mechanical stage, and high-brightness LED illumination, it delivers superior optical clarity and user comfort for academic, clinical, and routine laboratory applications.
Ideal for universities, research institutions, and diagnostic laboratories, the Mx21i combines modern optical technology with rugged design to ensure years of dependable performance in tropical environments.
Key Features
1. Infinity-Corrected Plan Optics
- Advanced plan achromatic objectives ensure flat, high-contrast images across the entire field of view.
- Tropicalized anti-fungal treatment safeguards optics against humid and fungal-prone environments.
- Uniformly centered, parfocal, and interchangeable objectives maintain image excellence over time.
2. Superior Imaging and Comfort
- WH10x (FN 20 mm) paired eyepieces with high eyepoint design minimize eye fatigue during prolonged observation.
- Compatible with optional eyepiece micrometer for measurement applications.
- Diopter adjustment on the left eyepiece tube ensures individual focusing precision.
3. Ergonomic, Student-Proof Design
- 30° inclined Seidentopf binocular head, 360° rotatable, with interpupillary adjustment (48–75 mm).
- Compact, ergonomic body made from aluminium die-cast housing with precision ball-bearing mechanisms.
- Designed for durability and ease of use — ideal for classroom or field environments.
4. Bright, Uniform Illumination
- Aspheric light relay system provides bright, evenly distributed illumination.
-
Available in three configurations:
a) 6V 20W halogen illumination (100–240V universal supply)
b) 3W LED illumination (30,000-hour lifespan)
c) 3W LED illumination with in-built NiMH battery back-up - Energy-efficient lighting ensures stable color temperature and minimal maintenance.
5. Precision Mechanical Stage and Focus
- Coaxial low-drive rackless stage (120 × 132 mm) with 76 × 30 mm travel range and single slide holder.
- Coaxial coarse and fine focusing system with 20 mm coarse range and 0.25 mm fine control for precision focusing.
- Rack and pinion-mounted Abbe condenser (N.A. 1.25) with continuously variable iris diaphragm and removable blue filter for daylight observation.
6. Expandable Modular System
- Supports optional attachments including Phase Contrast, Dark Field, Kohler, Fluorescence (EPILED), and Polarizing modules.
- Compatible with Magnus MagCam Digital Cameras (3MP / 5MP / 10MP / HD).
