The measurement method records an area and within just a few seconds, meaningful topographic measuring results of the surface texture can be provided. High-performance analysis software supports the individual depiction of the results and thus the quality assurance of the workpieces.</p><p>The optical measuring MarSurf WM 100 from the application specialist Mahr is a white light interferometer with a resolution in the sub-nanometer range. It has been designed especially for the quality assurance of the finest technical surfaces e.g. on optical elements or similar, polished, mirroring surfaces. The high-tech measuring system is currently mainly used by manufacturers of spheric and aspheric lenses. It enables analyses of the surface in 2D and 3D. The measurements take place within seconds and make it possible for decisively more workpieces to be tested within the production process more comprehensively and more reliably than with tradition testing methods.</p><p>The MarSurf WM 100 is ideal for the measurement of the smallest surface details. The measuring station measures topography, height, form and position on surface structure and reliably determines roughness, surface and flatness. It measures standardized 3D surface parameters as well as 2D roughness parameters on freely selectable lines or surface excerpts. The measuring method captures an area and the user receives informative, topographic measuring results of microscopic surface structures. The combined phase-shifting and short coherence interferometry provides the highest measurement precision even over λ / 2 jumps. The high-performance lenses minimize optical distortion errors.</p><p>An angle-adjustable measuring table allows precise positioning of the measuring object. Thus, for example, curved surfaces are positioned under the lens in an appropriate measurement position. A CNC controlled measuring table for fully automated measurements is also possible. The powerful software MarSurf MfM and MarSurf MfM plus enables an evaluation of the measurement results that is customizable to individual needs. A reduction of rejected parts and optimization of production that this measuring station makes possible amortizes the investment within a short period of time.</p></td></tr></tbody></table><table style="width: 400px;" border="0"><tbody><tr><td style="width: 370px;">Click here to download the picture</td><td style="width: 120px;"><a target='_blank' class='LinkMainContentArea' href=""><img src="" alt="" width="32" height="32" /></a></td></tr><tr><td>PP1098</td><td> </td></tr></tbody></table></span> 2014-04-09 00:00:00.000 2014-04-01: Our tip for you - quick calculation of a compensation circle (bore pattern) <span class='TextNormal'><table border="0" cellspacing="0" cellpadding="2" width="620"><tbody><tr><td width="305" valign="top"><img style="margin-left: 0px; margin-right: 0px; border-width: 0px;" src="" alt="" width="320" height="240" align="normal" /></td><td width="15" valign="top"> </td><td width="300" valign="top"><p><strong>The height measuring instrument Digimar 817 CLM “Quick Height”</strong></p><p>With the <a class='LinkMainContentArea' href="">Digimar 817 CLM </a>Quick Height, Mahr presents a versatile and comfortable height measuring device which shines especially through ergonomics and intuitive operation. For user-friendly operation, the <a class='LinkMainContentArea' href="">Digimar 817 CLM </a>offers all measuring and evaluation tools that are required of a modern height gauge in today's manufacturing and measurement laboratory.</p><p>The new height measuring instrument is available in sizes 350 mm, 600 mm and 1000 mm, and available with a 2D control and display computer so that the customer can select the right device for his needs.</p></td></tr><tr><td width="304"> </td><td width="18"> </td><td> </td></tr><tr valign="top"><td colspan="3"><strong>Ergonomics and handling:</strong><br /><p>With the Quick Mode that is unique worldwide, the user is now able to perform measurements without having to turn a hand crank or press a function key. The user merely positions the measuring slide and moves it briefly in the direction of the surface to be measured. The innovative system detects the direction of measurement and automatically starts the measurement. This greatly simplifies and speeds up the measurement of serial measurements, such as chain dimensions.<br />Starting the measurements using the operating computer has also been improved. With the quick keys with clear symbols, all measuring functions can be comfortably performed. A double assignment of the function keys was deliberately avoided.</p><p>The Quick Mode and user-friendly operation is just one of many highlights of the <a class='LinkMainContentArea' href="">Digimar 817 CLM</a>; the technology "under the hood" has also been further improved. Thus, the measurement accuracy for example is increased and the incremental measuring system has been equipped with a double reader head, which makes the device less sensitive to contamination of dirt on the measuring scale. The robust column is made of stainless steel and the measuring carriage is guided in precision ball bearings. In addition, temperature compensation is now possible with an internal temperature sensor.</p><p>Through the USB port on the control and display computer, measuring value lists, perpendicularity curves and statistics on a USB printer can be printed via a USB printer. In addition, measurement values and measuring programs can be saved on the internal USB memory. When connected to a PC in MS Windows, the USB memory is recognized as a removable drive, so that the files can be easily transferred and archived.</p><p> </p></td></tr><tr><td colspan="3"><p><strong>Measuring example: Measuring in 2D mode – ideal for the Quick Mode</strong></p><p>With the <a class='LinkMainContentArea' href="">Digimar 817 CLM</a>, popular 2D measurement tasks can also be solved such as the calculation of a compensation circle (bore pattern) or even angles and distances between holes. For this purpose, the measured values of both axes Z and X are measured separately and stored.<br />The procedure for 2D measurements is always the same: First the 2D function is activated and measures the characteristics in the Z axis. After a defined tilting/rotating of the workpiece (usually 90 °), there is a switch to the X axis and the characteristics are measured again in the same sequence in the X axis. Finally, the desired calculations are performed.
