NDT wedges

Rexolite or perspex wedges incorporate a pyramidal scattering surface with an impedance matched acoustic absorber to minimise internal reflections within the wedge.

NDT Wedges


Wedges can be designed and manufactured to custom specifications for use with any size or frequency of probe.

Internally scattered noise can be reduced by 13 dB by using a pyramidal textured wedge with impedance matched absorber versus a conventional pyramidal textured wedge without matched absorber.
