What is a Telecentric lens?

A telecentric lens is a special type of lens primarily used in machine vision systems and precision measurement instruments. Its unique feature is that the size and distortion of the image remain almost unchanged even if the object moves within the field of view. This lens ensures that the size of the object remains constant regardless of its position relative to the optical axis, making it ideal for precise measurement and inspection tasks. Telecentric lenses are often used in combination with zoom lenses and other types of lenses, allowing for highly accurate dimensional measurements of objects.

Application of Telecentric lens

✅Machine Vision Systems
Telecentric lenses are used in manufacturing lines for automobiles and electronics to precisely measure the dimensions of parts. This ensures accurate dimensional measurements even if the parts move relative to the lens.
✅Image Inspection
Telecentric lenses are used in the inspection of semiconductors and substrates to detect defects and scratches with high precision.
✅Medical Equipment
In medical equipment, telecentric lenses are used to observe internal structures such as cells with high resolution.
