Performance highlights
Engineered for precise industrial imaging
- Near-zero perspective distortion – Object dimensions remain highly consistent across the image.
- High measurement accuracy – Ideal for dimensional inspection and precision measurement.
- Constant magnification – Changes in object distance have very little effect on image size within the telecentric range.
- High image uniformity – Provides consistent image quality from the center to the edges.
- Large depth of field – Certain telecentric designs can maintain acceptable focus over a relatively large height range.
- Excellent edge definition – Suitable for detecting small defects and measuring object contours.
- Low optical distortion – Important for applications requiring reliable dimensional measurement.

Technical data
Product parameters
Telecentric Lens is a specialized optical lens designed for high-precision machine vision inspection and measurement. Unlike conventional lenses, it minimizes perspective distortion, allowing objects to be measured accurately even when their position or height varies.
