PCHI Series

The Opto Engineering PCHI optics are designed to easily inspect holes, cavities and containers. Unlike common optics or so called “pinhole lenses” which can only image flat fields of view, hole inspection optics are specifically designed to image both the bottom of a hole and its vertical walls.

PCHI Series lenses include options for 1/3”, 1/2”, and 2/3” sensors.

PCBP Series

The Opto Engineering PCBP probes are boroscopic probes for panoramic cavity imaging and measurement from inside. The catadioptric (refracting + reflecting) optical design ensures much higher resolution than fiber-based probes and enables the complete 360° inner view of the entire cavity. Boroscopic probes are intended to be handled by a robot arm or S.C.A.R.A. in order to scan even the deepest cavities.

PCPW Series

The Opto Engineering PCPW Series are polyview optics for multiple side views in one image. PCPW optics provide eight different views of the side and top surfaces of an object. The wide view angle (45°) enables the inspection of the side features of an object (for example the threads of a screw or a nut) otherwise impossible to acquire with a single camera. In addition to these unique features, PCPW optics also ensures excellent image resolution and image brightness.

PCMP Series

The Opto Engineering PCMP series lenses are micro-polyview optics for 3D measurement and imaging of small parts. The PCMP optics are designed to completely measure and inspect objects whose dimensions range from 1 to 10 mm. Six different lateral views are provided by an array of mirrors interfaced to a bi-telecentric lens; the top of the object is directly imaged at the center of the field of view. The lateral views feature exactly the same magnification and the images remain in perfect focus even when the object is displaced from its nominal position. The PCMP series integrates LED illumination optimized for this specific assembly.


The Opto Engineering TCCAGE Series is a bi-telecentric system for multiple side imaging and measurement at 90°. TCCAGE is an integrated optomechanical system designed to fully inspect and measure parts from the side without any need of rotation. Four orthonormal views of an object are provided by a bi-telecentric lens through an array of mirrors.

Each view is exactly at 90° with respect to the neighboring views; this optical layout ensures complete coverage of the object lateral surface. Furthermore, telecentric imaging makes the system insensitive to off-centered parts and therefore suitable for measurement applications.
