Polytec LSV Sensors: Process Optimization Starts with Precise Measurements

More and more Converting Plants are optimizing the process by replacing measuring wheels with the laser accurate LSv length speed sensors. The noncontact nature of the LSV eliminates the typical issues associated with contact methods such as slippage, changing circumference and marking of the product. There are a large range of application in plants processing films, foils, paper, cardboard,...

Substrate Tester detects HDD defects.

Designed for hard disk drive manufacturers, Model AVT-2000 detects defects at Substrate Grind, Nickel Plate, and First Polish process steps. Expedited recipe development is enabled by proprietary Defect Classification Assistant, which allows user to build detection algorithms with statistically based methodology. Empirical methods are used in DCA instead of legacy trial and error attempts.

Test & Measurement

Dimensional Metrology System has telecentric optical design.

Based on scanning white-light interferometry capable of 20 Nm resolution over vertical depth of up to 70 mm, TMS-100 can measure surfaces as large as 37 x 28 mm in single shot with lateral details as small as 36 -µm. It has protective housing with slight positive pressure against dust penetration, and includes actively regulated environmental vibration isolation table. Software and stages for...

Test & Measurement

Ultra High Frequency Vibrometer measures at up to 600 MHz.

Suited for studying high frequency MEMS or piezoelectric transducers used in medical ultrasound or NDT, UHF-120 can measure at amplitudes up to 100 m/sec with resolution of 30 fm/√Hz. It can be used in development of high spatial resolution ultrasound transducers for study of crosstalk between array elements, output uniformity and tissue interaction using phantoms. Laser Doppler Vibrometer can...

Laser Surface Velocimeter utilizes heterodyne technology.

Laser Surface Velocimeter utilizes heterodyne technology.

Model LSV-300 provides non-contact online measurement, inspection, and control of velocity and length in continuous process industries. It can distinguish between forward, reverse, and standstill motion conditions. With stand-off distances of 500 or 900 mm and 60 mm depth-of-field, device measures speeds to 2,500 m/min with accuracy of 0.05%. Two-line LCD displays velocity and length in English...

Geometry Scan Unit determines 3D shape of test objects.

Suited for Series PSV-400 scanning vibrometer systems, Geometry Scan Unit combines laser range finder with scan mirrors that position vibrometer beam. After defining measurement grid but prior to measuring test object's operational deflection shape, GSU can sample grid and construct geometry file for object. Within minutes 3D geometry model of structure can be plotted to monitor, giving static...

Optics & Photonics

Interferometer provides on-line part inspection.

Installed on manufacturing line, TopCam TMS-300/320 verifies production part flatness and topography. It can be controlled via operator interface software using COM/ActiveX or LabView(TM) drivers. Telecentric lenses allow imaging along high, steep edges and within deep, drilled holes. Measurements of surfaces with substantial relief are characterized by scanning Z dynamic range of 50 mm. Camera...
