Interferometer provides on-line part inspection.

Press Release Summary:




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 simultaneously acquires 325,000 point interferograms over field-of-view.

Polytec, Inc. Introduces an Industrial Interferometer for On-Line Flatness and Topography Measurements



November 23, 2004 - Tustin, CA - Polytec, Inc., a provider of advanced, light-based measurement systems to North America, announces a new, high-precision white light interferometer for on-line part inspection and production/quality control. Designed as a compact, industrial inspection system, the TMS-300/320 TopCam interferometer easily installs on a manufacturing line and rapidly verifies production part specifications for flatness and topography. Outstanding technical performance is accomplished by combining telecentric imaging with a Michelson interferometer, a precision scanning system and a digital camera. Working together, the integrated components produce extremely fast measurements over large fields-of-view (19 mm diameter) with z resolution of up to 10 nm.

Easy to integrate, the TopCam can be mounted in any direction and can be controlled via the operator interface software using COM/ActiveX or LabView(TM) drivers. Telecentric lenses allow proper imaging along high, steep edges and within deep, drilled holes. Measurements of imaged surfaces with substantial relief are easily characterized by scanning the large Z dynamic range (50 mm max.). The innovative TMS camera simultaneously acquires 325,000 point interferograms over the entire field-of-view.

The TMS software package includes all the necessary commands for instrument operation, data acquisition, analysis and presentation. Outstanding 2-D and 3-D data representation can be enhanced with profile cuts and filter algorithms.

Polytec, Inc., is a wholly-owned subsidiary of Polytec GmbH (Waldbronn, Germany).
