Large Stage with Dual Hand Adjustment
â—‹ To address the limitations of traditional horizontal guide rails, the new stage is designed with a dual-direction linear drive mechanism. This design prevents overload at the ends of the rails, enhances stage rigidity, and improves overall performance.
â—‹ The stage handle can be placed on either side to suit user preferences. The X-Y biaxial adjustment is positioned low for comfortable handling.
â—‹ Two slides can be held using damping-type double clips, making it easy for comparative studies. The moving range is 80mm x 55mm with a precision of 0.1mm.
â—‹ The stage surface is treated with special technology to be anti-corrosive and anti-friction. The arc transition design reduces stress concentration and impact damage.
â—‹ A light barrier helps reduce stray light, improving image contrast during fluorescence observation.
Modular Frame for Better Compatibility
â—‹ The NK-X50 features a modular design, separating the cross arm from the main body to improve compatibility between biological and fluorescence systems.
Highly Sensitive Coaxial Focus Adjustment
○ The coaxial focus system uses a dual-stage drive mechanism with adjustable tension and upper limit stop. The coarse adjustment range is 25mm, and the fine adjustment precision reaches 1μm. It allows accurate focusing and precise measurement.
Viewing Head with Multiple Splitting Ratios
â—‹ The NK-X50 viewing head offers multiple splitting ratio options. With a wide beam imaging system, it provides a 26.5mm super-wide field of view.
â—‹ The trinocular head with inverted image supports splitting ratios of 100:0, 20:80, or 0:100. This allows 100% light to be directed to the eyepiece or camera, or 20% to the eyepiece and 80% to the camera for simultaneous observation and image capture.
â—‹ The erect image trinocular head has a splitting ratio of 100:0 or 0:100, ensuring that the sample movement direction matches the observed direction.
