For the measurement of small parts (³ 1mm x 1mm) and for measurements in close, Polytec offers the PSV-I-400 scan unit. Equipped with either a 99.8 % or 97 % splitter. Includes a set of close-up lenses for video (1, 2 and 4 diopters) and a HE-NE block filter.

Options: PSV-A-CL-80, PSV-A-CL-150 and PSV-A-CL-300 Lenses with fixed 80 mm, 150 mm, and 300 mm stand-off distance, respectively.

Allows for measurements on small samples like hard disk sliders, read-write heads or ultrasonic actuators

Lenses for coaxial attachment to the PSV-A-410 for the measurements of very small parts or mirror-like surfaces.

Available for stand-off distances of 80mm, 150mm and 300mm.

Fiber optic ringlight for illumination of  the test object and contrast enhancement.

For translational positioning of the PSV-I-400 scan head when measuring small objects (e.g. HDD, DVD, etc.). Consists of a motorized three-stage telescope positioner, 90°-bracket for mounting PSV-I-400 scan head, drive electronics and control keypad, and base plate with metric and imperial hole patterns for mounting on standard optical tables. The microprocessor- controlled drive electronics allow positioning at three different speeds. The available positioning range of 300 mm covers all possible optical set-ups of the PSV-A-410 Close-Up Unit.

For housing and transporting the Data Management System, Vibrometer Controller and Junction Box. Wooden worktop for the TFT monitor, mouse and keyboard. Front and rear covers with storage space for the keyboard and the main connection cable. Removable bottom plate with wheels.

Laser-based distance sensor for the direct acquisition of 3-D geometry data. The Geometry Scan Unit comprises an optical distance sensor and full software integration with the PSV program (version 8.2 onwards) and it extends the capabilities of the PSV-I-400 scanning head to work as a 3-D geometry acquisition system. Attached to the PSV-I-400 scanning head it measures the x, y and z component of every defined measurement point or reference point. The Geometry Scan Unit includes software modules with the following features:

• User-defined object coordinate system
• Single-shot distance measurement
• Scanning distance measurement
• Visualization of geometry with overlaid vibration data
• Definition of reference points for 3-D alignment (PSV-400-3D)
• Geometry data export to UFF files
  
  

On smaller objects a software solution based on image processing is availble for PSV-400-3D systems: VideoTriangulation.

Not available for the PSV-400-B Basic Scanning Vibrometer.
