Opto Engineering PCBP

Boroscopic lens for internal measurements

The PCBP lenses are designed to inspect objects with holes such as engine parts, containers and tubes where the defects can only be monitored by using a small lens into the object.

The catadioptric (refracting + reflecting) optical design ensures much higher resolution than fibre-based probes and enables a complete 360° inner view throughout the entire cavity length.

Built-in illumination keeps the device very compact and makes it suitable for simple 3D applications by means of panoramic triangulation techniques.

High resolution

The catadioptric design enables the detection of small defects over a very wide view angle.

Flaw detection

Coarse deformations are revealed using direct illumination.

Surface defect enhancement

Mixing direct and indirect illumination makes it possible to emphasise tiny and barely visible defects.
