Stable Detection

[TECHNOLOGY FOR STABLE DETECTION]

Our first-in-class automatic focus mechanism has evolved even further. Recent advancements have allowed this mechanism to become more compact and achieve higher accuracy. By combining the automatic focus drive unit with the lens case in the optimal manner, our mechanism is 40% more compact than conventional. Also, by improving the durability of the drive unit, this compact automatic focus mechanism can operate over a wider range than conventional mechanisms.

Low Optical Distortion

HP-QUAD* Lens

The newly developed lens contains 4 layers of glass that achieve low aberration with high light-gathering power. It captures bright, clear images with low distortion for stable detection.
*High Precision-Quad

Hi-R* illumination

Our pursuit of an even more efficient reflectors with less LED light intensity loss has resulted in outstanding brightness and uniformity.
*High Reflection

Lighting Attachments

DOME LIGHT

Effective in reducing glare. Generating indirect light from various directions ensures the object is uniformly illuminated. No external power supply is necessary, which reduces introduction costs to 1/10th of conventional lights.
* This method is more effective than a polarization filter at reducing glare.

POLARIZED FILTER

Glare from glossy surfaces is reduced because only one direction of the light wave components is transmitted. The compact size enables easy installation.

Shape Detection

The matching percentage of the object is calculated based on the shape of the registered master image. Brightness differences or differences in individual surface conditions, which were previously difficult to handle with normalized correlation methods (pattern matching) can now be identified.

Area

Using the registered master area (number of pixels) as reference, the difference in area from the inspection object is calculated. When using a color model, judgment can be made based on the desired area of the specified color. When using a monochrome model, brightness is judged by the area binarized in black and white.

Position Adjustment

If the object is misaligned, 100% inspection cannot be achieved because the object may be outside the inspection area. The position adjustment function calculates the amount of misalignment from the master image in order to correct the position, and enable correct judgment. In addition, 360° rotation is supported for high speed tracking. This means you don’t need to worry about misalignment of the targets.
