The low magnification and large field of view bi-telecentric lens has good uniformity in the center of the field of view and around it and has extremely low distortion imaging, which is very suitable for high-precision workpiece appearance inspection and size measurement.
Detection object:
Auto parts inspection
Testing requirements:
- Whether the pins are crooked
- Hole measurement on parts
- Large field of view 145*100mm
- High precision
Difficulties in detection:
- It requires a large field of view and the resolution from the center to the edges of the field of view has to be highly uniform.
- At the same time for measurement, the distortion needs to be extremely low.
- Larger depth of field
Solution: DTCM230-190H-AL (DTCM series double telecentric lens) + surface light + 2/3″ 5M camera
