The Magnus Theia-i Freedom Binocular LED Microscope combines precision optical engineering with modern ergonomic design to deliver outstanding image quality, operational comfort, and reliability in educational, clinical, and research laboratories.
Equipped with plan infinity-corrected optics, inward-facing quadruple nosepiece, and built-in rechargeable LED illumination, this model is engineered for durability and flexibility — ideal for laboratories that require consistent performance even during power interruptions.
Key Features
1. Plan Infinity-Corrected Optical System
- Utilizes plan achromatic infinity-corrected objectives for flat, high-contrast images across the full field of view.
- Tropicalized anti-fungal optical coating ensures long-term clarity and durability, even in humid environments.
- Uniformly centered, parfocal, and interchangeable optical components provide precision alignment and ease of service.
2. Plan Achromat Objectives
- 4× / 10× / 40× (spring-loaded) / 100× (oil, spring-loaded) objectives with superior image sharpness and color correction.
- Enables accurate observation of biological, clinical, and material samples up to 1000× magnification.
3. Wide-Field Eyepieces
- WH10× (FN 20 mm) paired eyepieces with high eyepoint design reduce eye strain and provide wide-field clarity.
- Equipped with eyeguards and compatible with optional eyepiece micrometer for measurement applications.
- Left-tube diopter adjustment supports personalized focusing for each user.
4. Ergonomic Seidentopf Head
- Binocular head, 30° inclined and 360° rotatable, with adjustable eyepoint height at 370 mm or 430 mm for operator comfort.
- Interpupillary distance: 48–75 mm.
- Built-in locking mechanism prevents the observation tube from slipping or falling.
- Also available in Trinocular and Monocular variants for imaging or instructional use.
5. Inward-Facing Quadruple Nosepiece
- Precision ball-bearing mounted nosepiece provides smooth, positive click-stops for objective alignment.
- Inward-facing design enhances sample visibility and accessibility.
- Optional quintuple nosepiece available for extended objective configurations.
6. Illumination System with Battery Backup
- 3W high-brightness LED illumination (30,000-hour lifespan) ensures stable, daylight-balanced lighting.
- Built-in NiMH rechargeable battery backup provides continued operation during power outages — ideal for field or mobile laboratories.
-
Alternate configurations:
- 6V 20W halogen illumination with universal 100–240V AC supply.
- LED base illumination with collector lens system for uniform brightness.
7. Precision Mechanics
- Coaxial coarse and fine focusing controls (20 mm coarse range, 0.2 mm fine) deliver precise focusing at all magnifications.
- Rackless mechanical stage (125 × 145 mm) with dual-slide holder and 76 × 50 mm travel range for smooth and stable sample manipulation.
- Abbe condenser (N.A. 1.25) with continuously variable iris diaphragm and removable blue filter for enhanced contrast.
8. Durable Aluminium Die-Cast Construction
- Robust aluminium frame with ball-bearing and wire-guide mechanisms ensures smooth movement and long service life.
- Designed for stability, repeatability, and minimal maintenance under heavy use.
9. Expandable Modular System
-
Compatible with a range of optional accessories, including:
- Phase Contrast, Dark Field, Kohler, Fluorescence (EPILED), and Polarizing attachments
- Quintuple nosepiece upgrade
- 20× objective
- Magnus MagCam Digital Cameras (3MP / 5MP / 10MP / HD)
