Telecentric Lens
Telecentric Lens
Telecentric Lens is a special optical lens designed to ensure that light enters the lens parallel to the optical axis and forms a clear image on the image plane. This feature gives telecentric lenses significant advantages in measurement and detection applications. Telecentric lenses can reduce changes in image magnification caused by changes in object distance, thereby providing higher measurement accuracy and repeatability. In addition, telecentric lenses also have the characteristics of low distortion, large depth of field, and wide field of view, making them suitable for object detection and measurement in various complex scenes. In the fields of automated production lines, precision manufacturing, scientific research, etc., telecentric lenses play an important role in helping users achieve more efficient and accurate detection and measurement tasks.
Fine-Lens telecentric lens supports up to 1″ C-mount industrial cameras, with a telecentric optical path design of <0.1°, covering 0.17~1.5x, and coaxial optical design above 0.3. The maximum distortion of the whole system is <0.04%, which improves the measurement accuracy. It can be used for high-precision measurement and appearance defect detection, etc.
