自动变焦三维表面测量仪

The quality of indexable inserts is highly dependent on their geometry and surface properties. Durability, feed rates and overall machining properties are influenced by the cutting geometry such as cutting angle and radius. Traditionally, quality assurance methods for geometry accuracy have been restricted to tactile methods. However, tactile measurement devices do not allow the measurement of specific radii or angles due to the mechanical contact of the stylus to the surface. The optical 3D measurement device InfiniteFocus removes inaccuracies caused by tactile inspection methods. It provides highly accurate measurement of angle and profile plus the additional functionality of roughness, waviness. Also, the analysis of faults such as pits, scratches and contamination is possible. Due to the optical inspection quality, output and tool durability become approved.

Focus variation is employed,inter alia,for high-resolution measurement of plastic topographies with varying reflection properties and steep flanks.By meas of an optical 3D measuring system based on focus variation the leather-like grain on films can now be measured.In this way the regularity of grain elements before and sfter lamination can be quantified.

Surfaces with steep flanks and varying reflective properties are usually not measurable with conventional surface measurement techniques, even though there is an ongoing miniaturization of components and rising demand for automation in industry. A solution can be provided by “Focus Variation”, a new optical measurement technique that allows the robust measurement of complex surfaces with vertical resolutions up to 10 nm. In addition to topographic data, true colour information that is perfectly registered to the height data is obtained. The optical 3D measurement device “InfiniteFocus” is based on this new technology and provides a significant improvement in quality assurance. Allowing surface measurements in the micro and nano range as well as relatively large components, the Instrument can be used in the lab and as a measurement tool during production.

Currently technology to utilize laser pulses for the treatment of hard tooth structure is in well underway. Research and development efforts by the Dental Sciences and equipment manufacturers have placed great emphasis on the need to develop accurate methods to characterize and guide the development of this new method of dental treatment. Infinitefocus microscopy is a method of imaging and quantifying microscopic three- dimensional features. This unique optical reconstruction technique is referred to as “Topomicroscopy”. It is ideally suited to the evaluation of laser (and conventional) dental drilling procedures because of its ability to produce geometricallyaccurate, 3D color images and the corresponding volumetric data sets of drilled dental surfaces.
