Features:
1.High uniformity.
2.Suppresses the diffused light and achieves highly-directional lighting.
3.Improves curve edge detection.
4.The light from LED is illuminated on the same axis as the camera axis.
5.Compare to previous generation, the illuminance is 2 times better.
6.Provides a wide illumination range.

Major Applications:
1.Robots, ex: motor parts spot welding, placing wafer.
2.Multiple outline inspection.
