How to measure deflection shapes with a PSV Polytec Scanning Vibrometer in 5 easy steps

配件和组件

Optical Accessories

PSV-G-500 Geometry Scan Unit

Integrated laser distance sensor to measure the sample geometry.

PSV-A-440 Optical Derotator

For axial measurement of rotating objects. Locks onto the rotation and allows measurements as if stationary up to 24,000 rpm.

PSV-A-410 Close-up Unit

For close-up measurements, particularly on small parts. Includes a set of close-up lenses for the video camera. Special PSV-A-CL-xxx Micro Scan Lenses for small shiny parts available.

PSV-A-CL-xxx Micro Scan Lenses

Optimized beam path for measurements of very small parts or mirror-like surfaces. Requires PSV-A-410 Close-up Unit.

PSV-A-HNeBF Helium-Neon Block Filter

Notch filter for improved laser spot visibility when measuring very small parts or mirror-like surfaces.

PSV-A-RLight Ring Light

Fiber optic ring light for illumination of small test objects. Requires PSV-A-410 Close-up Unit.

PSV-A-526 Front Window

Protects the scanning mechanism against dust, wind and acoustic excitation at high dB levels.
