PCBP probes are used to inspect holed objects such as engine parts, containers and tubes whose hidden features can only be controlled by introducing a probe into the cavity. 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. Built-in illumination keeps the device very compact and makes it suitable for simple 3D applications by means of panoramic triangulation techniques.

KEY ADVANTAGES

Inspection of cavities from inside
Hidden internal features and defects are clearly viewed
High resolution
The catadioptric design enables the detection of tiny defects over a very wide view angle
Flaw detection
Coarse deformations revealed using direct illumination
Surface defect enhancement
Mixing direct and indirect illumination makes it possible to emphasize tiny and scarcely visible defects.

Glossary

PCBPN for inspection of holes with diameters between 5.5 and 25 mm

An integrated LED source (for PCBP0xx and PCBPN013-WG) illuminates the cavity both diffusely and directly. The diagram on the left shows the different illumination areas. Diffused illumination is used for defect detection and component inspection.

Direct/specular illumination can be efficiently used to check for surface deformation on metal and highly reflective objects as well as to measure the hole diameter.

The image of the cavity covers around 50% of the detector height: the continuous red line indicates the bottom view of the cavity, the dashed line shows the upper view while the dash-dotted line refers to the undercut view on the cavity.

Inspection area
PCBP probes can image cavities whose diameter ranges from 5 mm to 100 mm and over: the table below shows the inspection range allowed.
	Diameter (mm)	Height (mm)	Suggested P/N model
	5.5	3	PCBPN013
	10	6	PCBPN013, PCBPN013-WG
	15	9	PCBPN013, PCBPN013-WG
	20	12	PCBPN013, PCBPN013-WG
	25	9	PCBP0xx
	30	12	PCBP0xx
	40	18	PCBP0xx
	50	23	PCBP0xx
	60	29	PCBP0xx
	80	41	PCBP0xx
	100	53	PCBP0xx

PCBPN013-WG features an integrated powerful waveguide illumination with a 64 mm long probe for extra freedom and can inspect diameters down to 8 mm.

PCBPN013 allows to reach focusing on 5.5 mm diameters with a 64 mm long probe for extra freedom. Illumination is provided externally, e.g. using a matching backlight.

PCBP023 mounted onto a robotic arm.

The optical tip of the probe PCBPTIP (for PCBP0xx) can be easily replaced in case of damage.

The best focus in PCBP and PCBPN lenses is achieved by means of a lockable focusing ring. Power supply cables exit the device nearby the C-mount.
