TELECENTRIC

Feature
Produces high contrast and resolution in both the center and corners.
Virtually no TV distortion of entire image area.

Telecentric Optical System

In a telecentric optical system, there is no change in magnification when focusing. Thus, the magnification remains constant at different working distances. Similarly, the movement of an object also does not change the magnification, which makes a telecentric lens ideal for measuring objects with high accuracy.
In a telecentric optical system, the chief rays are parallel to the optical axis. As a result, the aperture becomes greater as the magnification is fixed by the focusing rays. This means that the F-number on a telecentric lens tends to be larger when compared to a standard megapixel lens.

Application Examples

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

2.0x for macro use
Able to resolve up to 21 megapixels
