DOUBLE REFLECTION CHROVIT

It is possible to simultaneously capture an oblique upper image of the workpiece and a direct-through front image. The figure shows three images: two side views of a cylindrical workpiece taken from a 45-degree oblique angle, and one central direct-through image.

The transport path of the workpiece is circular, and the CHROVIT is installed so as not to obstruct the transport path. With one stage, half of the workpiece can be inspected, and with two stages, a full 360-degree inspection can be done.

The figure shows three images: two side views of continuous hoop material workpieces captured from 30-degree oblique angles, and one direct-through top view of the workpiece. The setup ensures that the hoop material’s transport path is not obstructed, while a 30-degree CHROVIT is employed to capture the side views at the shallowest possible angle.

The 30-degree CHROVIT is more expensive than the 45-degree CHROVIT. This is because a reflective coating is applied to the areas in the optical path from the workpiece where total reflection cannot occur.

This CHROVIT is capable of imaging the side walls of depressions and counterbores from oblique angles above.
It is employed in situations where CHROVIT cannot be inserted into the workpiece due to constraints related to the transport system or cycle time.
Since CHROVIT is positioned at a distance above the workpiece, it does not interfere with the transport process.

The oblique downward viewing angle can be freely adjusted. However, due to the steep angle, the difference in focus between the top and bottom of the field of view becomes pronounced. Therefore, please select a lens with a deep depth of field.
