Description
Ergonomic Design, Convenient and Efficient
- Low torque stage
The low-position fixed stage and focusing mechanism enhance ergonomic comfort. Minimal hand movements allow for effortless specimen positioning, reducing operator fatigue.

- Observation tube
Wide-field trinocular tube with a 30° inclination. The FN 25 ultra-wide-field eyepieces can meet the needs of different scenarios.

- Light intensity management
The light intensity management system automatically sets the matching brightness levels for each objective. It maintains consistent illumination when switching from low to high magnifications, eliminating the need for frequent manual adjustments.

- Fluorescence Illumination System
Featuring a long-life, broadband, high-power LED light source, this system delivers uniform brightness with minimal maintenance. The spectral coverage spans from 350nm to 760nm, which can be turned on or off without preheating.

- Sextuple fluorescence module
Equipped with high-quality band-pass filter sets, these high-performance filters ensure vivid, bright, and uniform fluorescence observation. The filter sets can be replaced without tools.

- Semi-Apochromatic FLN objectives
Specially designed for high-resolution and high-contrast imaging, these objectives feature high fluorescence sensitivity to ensure exceptional sharpness, clarity, and color reproduction of the collected image.

Advanced Design Suitable for Multiple Observation Methods
- Brightfield observation
With a high-quality U-AC condenser for 20X–100X (oil) continuous observation, all magnifications can achieve high resolution and a flat field of view

- Fluorescence observation
The 6-position turret fluorescence module features user-replaceable filter cubes. With a wide variety of available filter sets, the system delivers a high signal-to-noise ratio, making it ideal for advanced applications such as FISH, FRET, and CTC detection.

- Phase contrast observation
High-contrast phase contrast images enable close-up observation of internal cellular structures and live bacteria. By using a phase contrast condenser, users can observe the phase contrast effects of the specimen

- Darkfield observation
Delivers good dark field observation from low to high magnifications with complete detail reproduction, meeting the requirements for observing fine details in biological tissues.
