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.
