This light transmission is detectable by two optical detection systems located on the other side of the web. Material-specific wavelength selection, light transmission angle changes, polarization slot diaphragms and transverse displacements of the light beam feeder along the optical X-axis result in extreme scattering and diffraction of the IR light photons in the boundary layer area on both sides of the sub nano layer within the substrate web. Their transmitted light intensity enables, after detection and evaluation, the determination of a direct relationship to the absolute surface tension. And this entirely independent of the material specific influences like: material and surface consistency, crystallinity, thickness, density, structure, polar grouping, temperature and type of pre-treatment. ---------------------------------------- Science/test results at our website http://www.microperforation.com/odstm-1-optical-dyne-control.html http://www.microperforation.com/engineerreport.html http://www.microperforation.com/mll-1-laser-perforation.html http://www.microperforation.com/lpm-1.html http://www.microperforation.com/opss-1-optical-online-porosity.html http://www.microperforation.com/igbt-esp-unit.html http://www.microperforation.com/online-perforation-cigarette.html ---------------------------------------- ---------------------------------------- IPM International Perforation Management hi-tech engineering, Asia, Germany, Thailand Mr. Werner Grosse Tel./fax : 0049-3212-5097465 http://www.microperforation.com http://www.deguodaguan.com/ipm/ ----------------------------------------
