Endoscope lens

What is a Endoscope lens?

An endoscope lens is a critical optical component designed to provide high-resolution imaging in medical diagnostics.

Endoscope lenses deliver clear, accurate, and distortion-free images even in confined or hard-to-reach areas.

Chenyu offers a superior quality lens optimized for endoscopy.

Chenyu integrates the advanced technology of steering prism and electronic endoscope, bringing users a clearer and more accurate internal observation and diagnosis experience.

 

Key Features of Endoscope Lenses

 

• High Image Clarity：Ensures sharp visualization with minimal distortion.

• Wide Field of View：Enables comprehensive observation in small or complex environments.

• Compact and Lightweight：Perfect for integration into minimally invasive devices.

• Durability：Resistant to heat, pressure, and repeated sterilization processes.

• Material Options：Manufactured from high-quality optical glass, sapphire, or biocompatible materials.

The working principle of medical-grade endoscopes

 

The core of medical endoscopes lies in optical imaging and lighting technologies.

By illuminating the human body’s cavities with cold light sources, the lens transmits the image to the camera, which then presents a high-definition picture through the display system.

Some high-end devices also feature 4K imaging, narrow-band imaging (NBI), and 3D visualization technologies.

The advantages of endoscopes

 

• High-definition imaging：The endoscopes can present clearer details of the tissues.
• Minimally invasive examination：Compared with the common endoscopes, the medical grade endoscopes can make less pain and faster recovery.
• Multifunctionality：People often use them for diagnosis, biopsy and minimally invasive surgery.
• Safe and reliable：The material complies with medical standards and can be sterilized under high temperature and high pressure, ensuring no cross-infection.
• Advanced technology：supports high-definition/4K video output, AI-assisted diagnosis, and wireless transmission.

The application fields of medical-grade endoscopes

 

• Gastroenterology Department

It can be used in some checking devices.

• Respiratory Department:

For diagnosing lung diseases.

• Otolaryngology:

Nasal endoscopy and laryngoscope.

• Orthopedics:
