OPTV 38 & 52 : Optical Televiewer

A precision wide angle lens and a CMOS camera assembly permit the OPTV38 and OPTV52 probes to capture a high-definition video image of the borehole wall in a variety of horizontal and vertical resolutions.

​

The resulting image data is digitised in the probe and combined with orientation sensor parameters for transmission to the surface.

​

The orientated image log provides a wealth of information relevant to a wide variety of applications. These include fracture detection and analysis, bedding or foliation dip and direction, lithological characterisation and core sample orientation.
