● Observation head

Equipped with a three eyed observation head, the observation head can usually be disassembled and replaced to meet different observation needs. This flexibility allows users to choose the appropriate observation head based on specific application scenarios. Can be equipped with an imaging system for use.

● High eye point and large field of view eyepiece

The adjustable range of pupil spacing is between 46-75mm, ensuring that each user can make precise settings according to their own conditions. The eyepiece with high eye point design has adjustable binocular vision, making binocular observation easier and providing users with a more comfortable user experience.

‌●Infinite flat field achromatic objective lens and converter

This series of objective lenses adopts innovative design methods and concepts, with a wider field of view, which can make the color reproduction of images more realistic. It has the characteristics of beautiful appearance and easy operation, which meets the requirements of ergonomics and makes the operation more comfortable and convenient.

The inward facing 4-hole converter greatly improves the flexibility of using microscope objectives and is easy and fast to operate. Reduced errors caused by frequent lens replacement and improved observation stability. Capable of providing clear images, suitable for high-precision observation and experimentation.

●Double layer mechanical loading platform

Stably support and fix the sample to ensure the stability of its position and shape during observation. Equipped with a scale ruler, it facilitates the positioning and measurement of specimens, improving the accuracy and efficiency of experiments. It has the characteristics of corrosion resistance and wear resistance.

●Abbe condenser

Abbe spotlight has excellent focusing performance and can effectively converge light. It has a simple structure and high transmittance, suitable for bright field observation under a microscope. The high numerical aperture characteristic enables it to provide higher resolution and deeper depth of focus, making it suitable for situations that require high-precision observation. Equipped with variable light bars, this provides users with more observation and experimentation options.

●Lighting System

The microscope is equipped with an integrated LED light source that uses high brightness LED beads to provide sufficient illumination intensity, ensuring that the details of the sample are clear and visible. It can provide uniform lighting, reduce the problems of shadows and uneven brightness, thereby improving the accuracy and detail expression of observation. And LED lights are more environmentally friendly, meeting the requirements of modern laboratories for environmental protection. ‌‌‌‌

●Focusing handwheel

Coarse and fine adjustment coaxial, with fine adjustment focusing mechanisms on both sides of the stage operating handwheel for precise focusing. Enable users to easily switch between coarse and fine tuning during observation, improving work efficiency. The coaxial design makes the operation more intuitive and convenient, and users can easily grasp the force and direction of focusing, reducing fatigue during operation.

●Back storage

This function can effectively store and protect power cords from damage caused by external factors. This not only extends the service life of the cable, but also ensures the safe and stable operation of the equipment. It can effectively reduce cable entanglement and damage, thereby avoiding unnecessary maintenance and replacement costs.
