In the field of industrial vision, the choice of lens plays a crucial role in image quality and inspection accuracy. Telecentric lenses and FA lenses are two common and important types of lenses, each of which has unique advantages, similarities, and significant differentiating features.

The same point:

Both telecentric and FA lenses were originally designed to provide high quality images in industrial inspection and imaging. Both utilize advanced optical technologies and manufacturing processes to ensure clear, accurate imaging. And, they are both able to adapt to a variety of complex industrial environments with a certain degree of durability and stability.

Advantage:

The advantage of telecentric lenses is that they eliminate perspective errors, provide constant magnification, and keep the size and shape of the image stable regardless of changes in the position of the object. This allows telecentric lenses to excel in applications such as high-precision measurement and defect inspection where size and shape accuracy are critical.

FA lenses, or Factory Automation lenses, typically feature a large aperture and high resolution, enabling clear imaging at short working distances for inspection and monitoring tasks on automated production lines that require high speed and efficiency.

Differentiation:

Imaging Principle

Telecentric lenses are based on a telecentric optical path design, which is primarily designed to eliminate the effects of parallax and depth of field to ensure accurate measurements. FA lenses, on the other hand, are more focused on providing clear, bright images at a certain working distance.

Application Scenarios

Due to the high accuracy of telecentric lenses, they are commonly used in precision measurement, semiconductor manufacturing, medical equipment, etc. FA lenses are more commonly used in industrial automation for rapid inspection, sorting and positioning.

Telecentric lenses and FA lenses have irreplaceable roles in the field of industrial vision. In practical application, according to the specific needs and budget, choose the right type of lens, will be able to greatly improve production efficiency and detection accuracy, for industrial production to bring higher quality assurance and economic benefits.
