As the core component of the endoscope imaging system, the endoscope objective lens is the key to achieving accurate medical diagnosis. It is like the "eye" of the endoscope, presenting the complex internal structure of the human body to medical workers in a clear and real image, providing an important basis for disease diagnosis and treatment.

Core structure design

The endoscope objective lens adopts a design of precise combination of multi-layer optical lenses and is made of high-refractive index, low-dispersion high-quality optical glass. By accurately calculating the curvature, thickness and spacing of each lens, various optical aberrations such as spherical aberration and chromatic aberration can be effectively corrected to ensure accurate focusing of light. The barrel part uses high-strength, corrosion-resistant medical-grade materials, which not only ensures the mechanical stability of the objective lens, but also meets the strict disinfection requirements of the medical environment. In addition, the front end of the objective lens is also equipped with a special sealing structure to prevent the intrusion of human body fluids and water vapor, avoid damage to optical components, and extend the service life of the product.

Excellent performance characteristics

1. Ultra-high resolution imaging: With advanced optical design and high-quality materials, the objective lens can achieve extremely high resolution, clearly capture micron-level tissue details, help doctors accurately identify subtle features of lesions, and provide strong support for early disease diagnosis.

2. Wide field of view: With a large field of view design, it significantly expands the observation range compared to traditional objective lenses. One inspection can cover more areas, greatly improve inspection efficiency, and reduce the risk of missed diagnosis due to limited field of view.

3. Excellent depth of field performance: With good depth of field characteristics, it can make tissues at different depths clearly imaged at the same time, without frequent adjustment of focal length, which is convenient for doctors to quickly and comprehensively observe the internal structure of the human body and improve the accuracy and fluency of diagnosis.

4. High transmittance and low distortion: The use of special coating technology greatly improves the transmittance of the lens and reduces light loss; at the same time, it effectively controls image distortion, ensures the authenticity and reliability of the image, and provides accurate visual information for medical diagnosis.

Wide range of application areas

Endoscope objective lenses are suitable for a variety of medical scenarios and can be adapted to various endoscopic devices such as gastroscopes, colonoscopes, bronchoscopes, and laparoscopes. They are widely used in multiple medical fields such as the digestive system, respiratory system, urinary system, and gynecology. Whether it is screening for digestive tract diseases, diagnosing respiratory tract lesions, or real-time observation in minimally invasive surgery, they can play an important role and help medical workers make more accurate diagnosis and treatment decisions.
