Large Stage with Dual-Hand Adjustment

â—‹ To address the limitations of traditional horizontal guide rails, the new stage features a dual-direction linear drive mechanism. This design prevents overload at the end of the rails, enhancing the rigidity and performance of the stage.

â—‹ The stage handle can be placed on either side according to user preference. The X-Y axis adjustment is designed at a low position for comfortable handling.

○ Two slides can be securely held using damping-type double clips, making comparative studies easier. The moving range is 80mm × 55mm, with a precision of 0.1mm.

â—‹ The stage surface is treated with special craftsmanship to resist corrosion and friction. The arc-shaped platform design reduces stress concentration and minimizes damage from impacts.

â—‹ A light barrier is included to reduce stray light, improving image contrast during fluorescence observation.

Modular Frame for Enhanced Compatibility

â—‹ The NK-X50 is designed with a modular structure, separating the cross arm and main body to improve compatibility between biological and fluorescence systems.

Highly Sensitive Coaxial Fine Adjustment

○ The coaxial focus mechanism uses a two-stage drive system with adjustable tension and a top limit stop. It offers a coarse adjustment range of 25mm and fine precision of 1μm, allowing accurate focusing and precise measurement.

Multi-Ratio Viewing Head

â—‹ The NK-X50 viewing head offers multiple splitting ratios. With a wide beam imaging system, it provides a 26.5mm super-wide field of view.

â—‹ The trinocular head with inverted image allows splitting ratios of 100:0, 20:80, or 0:100. This enables both eyepiece and camera use simultaneously by directing 20% of the light to the eyepiece and 80% to the camera.

â—‹ The erect image trinocular head supports splitting ratios of 100:0 or 0:100, with sample movement direction matching the observed direction.
