Method and device for optical inline touch less surface tension
control ODSTM-1 in DE19543289 by which the fast moving substrate
through the measuring gap.

It’s transmitted with a chromatic beam and spectral selected light
source were two optical channels are displaced and polarized by 90
degree to each other. Both optical axles are precise and motor driven
shift able in certain angles from 25-65 degree. The spectral light
photons, transmission, extinction, absorption grades are detectable by
two optical CCD imagine vision devices, integrated into the sensor
case on other side of the substrate.

Material condition
At high speed moving substrates means plastic foil, flexible, hi-tech,
film, laminate, coating, bonding, labeling, co-extrusion, BOPP, LDPE,
LLDPE, HDPE, MDPE, MAS, MOH, MEV, PET, FEP, PP, PE, PS, PO, EVA, PTFE,
PVC, PTFE, Vinyl, Polyester, wrapping, self-adhesive tape, high
strength, cross laminated, adhesive coated films, reflective or
magnetic sheeting, automotive tape products, inkjet, heat sealing,
security, pressure sensitive tapes for entertainment or building
industry, masking or printable plastic films, polycarbonate, acrylic,
extruded or polished cellulose, optical grade polycarbonate, sheets
for IR or laser protection, filter sheet, imaging, capacitors, bi-
oriented polystyrene sheet, multilayer co-extruded film, PVC, PETG,
polyimide, tear tapes for aerospace, inner covering in aircrafts,
automotive, medical, bioengineering, renewable, agriculture, marine,
household, commercial, domestic, construction, high-porous membranes
for uses in alkaline lithium ion batteries, fuel cells, filtration
equipment.

By gauges from 10 up to 500 microns, fabric widths up to 10,000 mm and
web speeds up to 18 m/s.

Optical properties and quality control
Material specific wavelength selection from 1200 up to 1800 nm,
material specific finger prints, molecular spectral properties,
transmission, optical angle scanning, ultra low level stray scatter
light detection, polarization, slot diaphragms, transverse
displacements control the light beams along and far from the optical X
and Y axes. The results are extreme scattering, diffraction, NIR, IR,
stray light photons generation into the layer areas at both sides of
the moving substrate.

Their reflected and transmitted light intensities enables the
determination by defined formulas and data matrixes the surface
tension values in ranges from 28-62mN/m or dynes which are direct
associate and bond to real static values for statistical quality
control (SQC).

And this entirely independent of the material specific influences as
like surface consistency, thickness, density, weight, opacity,
coherence, filling, stretching, shrinkage, structure, co-extrusion,
polar grouping, temperature, intrinsic motivation or viscosity,
hydrophobia, hydrophilic molecules, hydrogen, moisture, water steam
proof, bi-layer, polymer, patterning, nanostructure, irradiation,
isotopic, catalyst, coherence, absorption, photo mask effect,
radiation, resonance bands, Raman, electron spectroscopy for chemical
analysis ASTM or ATR method, property, acoustic photonic liquid
effects, pre material treatment as corona, plasma jet, flam
treatment.
