2D-LDV probe fp50 shift

The 2D LDV probe is based on the design of the fp50 shift probe. It is based on the approach of building LDV probes with built-in lasers and without optical transmission fibres. The main advantage of this approach is that between 80 and 90 % of the laser power is transferred to the measurement volume; in addition, the costs are reduced by eliminating the additional optical fibres.

Two Nd:YAG lasers are built into the probe, with wavelengths of 532 and 561 nm and a maximum power of up to 500 mW.
