Telecentric Lenses

A telecentric optical system is often critical in machine vision systems. The LM50TC is Kowa’s unique optical design seamlessly incorporates zoom capability with telecentric function.

All new telecentric lenses have very low distortion. They produce high contrast and resolution in both center and corners.
In a telecentric optical system, there is no change in magnification when focusing, and magnification is constant over working distances. Thus movement of an object does not change magnification. Therefore, it is suitable for measuring objects with high accuracy.

• Surface inspection of silicon wafers
• Image defect inspections
• Inspection of dirt on prisms and glass circuit boards
• Measurement of thread pitches
• Reading 2D codes
