Key Features
1. Semi-Plan Achromatic Optical System
- Features semi-plan achromatic optics for sharp, flat-field imaging across the entire field of view.
- Infinity-corrected, anti-fungal treated optical components ensure long-term image clarity, even in humid environments.
- Uniformly centered and parfocal objectives maintain consistent focus during magnification changes.
2. Objective and Eyepiece Configuration
- Equipped with Semi-Plan Achromatic Objectives: 4×, 10×, 40× (spring), and 100× (oil, spring).
- HWF 10× (FN 18 mm) paired eyepieces with eyeguards minimize eye strain and provide wide-field viewing.
- Optional eyepiece micrometer available for measurement applications.
- Magnification range: 40× to 1000×.
3. Observation Head
- Binocular head inclined at 45°, 360° rotatable, with diopter adjustment on the left tube.
- Interpupillary distance: 53–75 mm.
- Also available in Trinocular and Monocular configurations.
- Ergonomic viewing angle reduces neck fatigue during extended sessions.
4. Bright, Uniform Illumination
- 3W LED illumination system provides high brightness and 30,000-hour lifespan.
- Available with built-in rechargeable NiMH battery backup for uninterrupted use during power fluctuations.
- Halogen 6V 20W variant available for traditional illumination preferences.
- Pre-centered light collector system ensures bright, even illumination with minimal maintenance.
5. Precision Focusing and Stage Design
- Coaxial coarse and fine focusing system with 20 mm coarse range and 0.2 mm fine control for precision adjustments.
- Rackless mechanical stage (125 × 145 mm) with a traverse area of 76 × 30 mm for smooth, stable slide movement.
- Single-slide holder enables easy sample handling.
6. N.A. 1.25 Abbe Condenser
- Rack and pinion-mounted Abbe condenser (N.A. 1.25) with continuously variable iris diaphragm.
- Removable blue daylight filter enhances contrast and color correction for natural viewing.
- Pre-centered design ensures even illumination across all magnifications.
7. Rugged and Ergonomic Construction
- Aluminium die-cast frame ensures long-term durability and alignment stability.
- Precision ball-bearing and wire-guide mechanisms guarantee smooth, precise stage movement.
- Compact, balanced design ideal for student and teaching environments.
8. Expandable System with Optional Accessories
-
Compatible with a wide range of optional accessories, including:
- Phase Contrast, Dark Field, Polarizing, and Drawing Attachments
- Plan objectives for upgraded optical performance
- Magnus MagCam Digital Cameras (3MP / 5MP / 10MP / HD) for imaging and documentation
