What are Telecentric lenses?
Telecentric lenses are specialised optical lenses designed to keep magnification consistent regardless of the object’s distance from the lens. They achieve this by ensuring that light rays pass through the lens parallel to the optical axis. This eliminates perspective distortion, making them ideal for precision measurement and metrology applications.
What advantages do Telecentric lenses offer in industrial imaging?
- Accurate dimensional measurement without perspective distortion
- Consistent magnification across different object depths
- High optical precision for reliable inspection results
- Robust mechanical design for stable performance in industrial environments
Which applications benefit most from Telecentric lenses?
Telecentric lenses are widely used in:
- Dimensional measurement and metrology
- Automated optical inspection (AOI)
- Semiconductor and electronics inspection
- Machine vision systems requiring distortion-free imaging
- Scientific and research imaging with high accuracy demands.
Can telecentric lenses improve image quality compared to standard lenses?
Unlike conventional lenses, telecentric lenses eliminate perspective errors by maintaining parallel light rays. This ensures that objects at different heights or depths appear at the same scale, providing precise and repeatable measurement results.
Are Schneider-Kreuznach telecentric lenses compatible with different sensor formats?
Yes, the SYLVINE and THULITE series, for example, are designed to cover sensors up to 2/3” with magnifications ranging from 0.2x to 1x, ensuring optimal performance for various industrial cameras.
Can Schneider-Kreuznach telecentric lenses be customized?
Yes. We can develop custom solutions to meet your specific requirements, including adjustments to the magnification, optical design or ruggedized housing. This ensures that the lens fits seamlessly into your machine vision system.
