OFV-153 Adjustable Reference Head
| For optimized performance of single point measurements with the OFV-552 Differential Sensor Head. The OFV-153 Adjustable Reference Head terminates the reference fiber when working in single-point mode. A slider allows adjustment of the optical path length in the reference fiber, thereby providing means to set the system to the visibility maximum.

OFV-SR/OFV-MR/OFV-LR/OFV-SLR Front Lens
| By using different front lenses with the single-point sensor head the vibrometer is optimally adapted to different stand-off distances and depths field. The longer the focal length of the objective the higher is the signal level at the same stand-off distance whereas the depth of field decreases. Exchange of front lenses is swift and easy. |
