Telecentric lenses are a special type of lens used as a complementary type to industrial lenses and are mainly used in optical systems for imaging, metrology and machine vision applications.
1、The main function of telecentric lens
The functions of telecentric lenses are mainly reflected in the following aspects:
Improve image clarity and brightness
Telecentric lenses can make images clearer and brighter by refocusing light and controlling its direction. This is very important for improving the imaging quality of optical instruments, especially when it is necessary to observe small structures or low-contrast samples.
Eliminate distortion
Through strict processing, manufacturing and quality inspection, telecentric lenses can effectively reduce or eliminate lens distortion and maintain the accuracy and authenticity of imaging.
Extended field of vision
Telecentric lenses can also help extend the field of view, allowing the observer to see a wider area, which helps to fully observe the target sample. Therefore, telecentric lenses are also often used to shoot dangerous environments such as wildlife and war scenes. Photographers can shoot far away from the subject, reducing risks.
For photographing wildlife
Adjust the focus
By adjusting the position or optical parameters of the telecentric lens, the focal length can be changed to achieve imaging effects of different magnifications to meet different observation needs.
Due to its long focal length, the telecentric lens can “bring close” distant objects, making the image larger and clearer, and is often used to shoot sports events, wildlife and other scenes.
Compress visual distance
When shooting with a telecentric lens, objects in the image will appear closer, thus compressing the visual distance. This can make the picture look more layered when shooting buildings, landscapes, etc.
2、Common application areas of telecentric lenses
Astronomy
In astronomy, telecentric lenses are mainly used in telescopes and astronomical observation equipment to help astronomers observe various celestial bodies in the universe, such as planets, galaxies, nebulae, etc. Telecentric lenses with high resolution and high sensitivity are very important for astronomical observations.
For astronomical observation
Photography and videography
Telecentric lenses play an important role in the field of photography and videography, helping photographers take clear, high-quality photos and videos. Telecentric lenses can adjust the focal length, control the depth of field, and reduce distortion, thereby improving image quality.
Medical Imaging
Telecentric lenses are widely used in medical imaging, such as endoscopy, radiography, ultrasonic imaging, etc. Telecentric lenses can provide clear and accurate images to help doctors make quick and accurate diagnoses.
Optical communication
In the field of optical communications, telecentric lenses play an important role in fiber optic connection and modulation and demodulation. In fiber optic communication systems, they mainly help adjust and focus optical signals to achieve high-speed, high-quality data transmission.
Laser processing
Telecentric lenses are also widely used in the field of laser processing, such as laser cutting, laser welding, laser engraving, etc. Telecentric lenses can help the laser beam focus on the target position to achieve precise processing and efficient production.
Scientific research
Telecentric lenses are widely used in various scientific research fields, such as biology, material science, physics, etc. Telecentric lenses can help researchers observe tiny structures, conduct experiments and measurements, and promote the progress of scientific research.
