Multi-field application of rod lens

Rod lens imaging has a wide range of applications, the following are some common application areas:
Medical field
Endoscope: Rod lens is one of the key components of hard tube endoscope. Rod lens can realize the transmission and imaging of light in a small space, help doctors observe the condition of the internal organs of the human body, and is of great significance for the diagnosis and treatment of diseases. For example, in some minimally invasive procedures, the doctor can see the details of the surgical site clearly through the rod lens imaging system in the endoscope, so that the surgical operation can be more accurate.
Laser medical treatment: In laser surgery, the rod lens can be used to shape and focus the laser beam, so that the laser can act more accurately on the diseased tissue, improve the treatment effect, and reduce the damage to the surrounding normal tissue.
Communication field
Fiber coupling: The rod lens can efficiently couple the light emitted by the light source into the fiber, improving the optical signal transmission efficiency of the optical fiber communication system. By reasonably designing the shape and parameters of the rod lens, the light can better match the numerical aperture of the optical fiber, so as to achieve higher coupling efficiency and ensure the stable and efficient transmission of optical signals in the optical fiber.
Industrial field
Laser processing: In industrial processes such as laser cutting and welding, rod lenses can be used to shape and focus the laser beam to obtain the desired spot shape and energy distribution. For example, focusing the laser beam into a small spot can improve the cutting accuracy and welding quality to meet the needs of different industrial processing.
Machine vision: In some industrial inspection and automated production lines, rod lens imaging systems can be used to image and detect objects. Through the special imaging characteristics of the rod lens, high-precision imaging and measurement of the object can be achieved, helping the machine to identify and judge the quality, size and other parameters of the product, and improving production efficiency and product quality.
Lighting field
LED lighting: The rod lens can be used as a light guide column to focus and guide the light emitted by the LED to achieve a uniform lighting effect. For example, it is used in the display backlight and indicator light of some electronic products, which can improve the utilization rate of light and lighting effect.
Scientific research field
Optical experiments: rod lens can be used as a special optical element in optical experiments to study the propagation, refraction, focusing and other phenomena of light. By changing the parameters and experimental conditions of rod lens, we can deeply understand the properties of light and optical laws, and provide basic support for the development and application of optical theory.
Laser technology research: In the field of laser physics, laser technology and other scientific research, rod lenses are often used to study the regulation and characteristics of laser beams. For example, researchers can use rod lenses to shape and focus laser beams, explore new phenomena and new laws of interaction between laser and matter, and promote the innovative development of laser technology in various fields.
Security field

Surveillance camera: Some surveillance cameras will use rod lens imaging technology to achieve a specific Angle or a specific shape of the imaging effect, to meet the monitoring needs of different scenes, such as in some need wide-angle or telephoto imaging monitoring environment, rod lens can help the camera to obtain a broader field of view or clearer long-distance images, improve the effect and reliability of security monitoring.
