The new inside inspection sensor Hommel-Etamic IPS10 from Hommel-Etamic enables the automatic inspection of bores with a fast 360° all-round view.

Inspector-independent surface evaluations with industrial image processing are constantly reproducible and allow the detection of the slightest flaws with many different classifications. Specially designed for automatic inspection inside bores the new inside inspection sensors from Hommel-Etamic Opti-Sens Technology feature extraordinary scanning speeds and compact dimensions.

The basis of the new sensor is a 360° all-round optic which transmits the peripheral lines of the bore to the image plane of the inspection sensor by an endoscopic system and projects them there as circle lines. The contour lines are scanned continuously in a ring cycle by CMOS image sensors. Simultaneous forward movement in the bore produces a complete image of the inside surface which displays the layout. The pixels in every scan in peripheral direction and the incremental encoder of the linear traverse unit axis form the dimension bodies. The result is undistorted, accurately dimensioned, high resolution and complete views of the inside surfaces.

The all-round optic of the Hommel-Etamic IPS10 is so compact that bores up to a minimum diameter of 14 mm in inspection lengths up to 156 mm (optional 456 mm) can be inspected. A peripheral resolution of 2,800 pixels on 360° allows the detection of the slightest flaws. With scan rates up to 10,000 scans per second the Hommel-Etamic IPS10 supplies excellent images at an enormous recording speed. This enables short inspection cycles in sync with the ongoing production.

The company belonging to the Industrial Metrology Division of Jenoptik offers the new Hommel-Etamic IPS10 inside inspection sensors as standalone systems with application-specific equipment, i.e. adapted workpiece handling, for integration into production lines.
