Advanced Surface Metrology

Optimap3, the unique portable solution for surface inspection, allows rapid large area measurement and analysis of all types of coated or uncoated surfaces.

Powerful on-screen functionality includes cross-sectional viewing allowing detection and characterisation of common surface irregularities including defects and waviness.

In quality control, inferior surface evaluation methods are still commonplace. Many methods lack definition, are time consuming and subjective. Modern consumers demand high quality products with surface finishes that are homogeneous and free from defects.

The use of Optimap3 provides a unique solution to these measurement challenges providing quantifiable data for improved production control.

In one fast operation Optimap3 maps the topography of a surface displaying defects and texture in incredible detail. Mapped information is processed into objective surface data that can be used to effectively control product quality.

The Optimap 3 can measure

  • Orange Peel
  • Waviness
  • DOI
  • Overspray
  • Inclusions
  • Blistering
  • Sagging
  • Waterstains

Representative surface analysis

Optimap3 objectively measures and characterises many aspects of surface quality including texture, waviness and local defects including orange peel, inclusions, dents and scratches.

Its large measurement area (65 x 54mm) and speed of operation (under 10 secs) provides rapid measurement with results that are more representative than those made with profilometers or other optical scanning instruments and can be reported in traceable SI units or other industry specific units.

With a lateral resolution of <37um Optimap3 has the power to capture surface defects that are invisible to the human eye.

Results comparable to profilometry and other optical measurement techniques

Non-contact measurement for wet paint

The ONLY product that can measure the formation of orange peel of wet paint

Compatible with visual appearance scales

(TAMS and Wavescale values) used in automotive and high end applications

Benefits of using the Optimap3

How does the Optimap3 measure and analyze surfaces?

Optimap3’s intuitive user interface provides operation, setup and display of measurement results.

The icon based touch screen allows ease of use by simply pressing the relevant active areas on the screen.

Optimap 3 product with hand

Phase Measurement Deflectometry (PMD) is used to map surface topography

Fringe patterns are displayed on an internal target screen.

The Fringe Patterns are animated (phase stepped) in X & Y directions.

Optimap 3 dull mode
Dull surface
Optimap 3 reflective mode
Reflective surface

The Optimap3 has two modes – reflective and dull

High frequency fringes are used to measure reflective surfaces – low frequency for dull surfaces.

Optimap 3 diagram

The PMD is a non contact technique using white light reflection

The fringe patterns are reflected by the surface- the reflection is distorted by surface texture and defects.

The reflected images are captured by an internal variable focus camera.

optimap 3 screen graph

High resolution maps show surface texture and defects

The built in PMD surface mapping engine combines data from 8 reflected fringe patterns to create a highly representative map of the measured surface.

Maps of surface curvature or altitude can be displayed. High resolution maps show surface texture and defects. Built in profile tool can be used to measure the height and size of surface features.

Intuitive user interface

Optimap3’s intuitive user interface provides operation, setup and display of measurement results.

The icon based touch screen allows ease of use by simply pressing the relevant active areas on the screen.

Optimap 3 graph - cross sections

Cross sections can be created through the surface by touching the relevant point of interest on the displayed image and viewing the chart in the upper display.

The cross section is active and can be moved over the image in X and Y to view changes across the surface.

The magnification of the image can be adjusted via magnification slider.

Instrument verification

Due to the PSD measurement principle, the Optimap requires no calibration.

It is recommended however that a verification check is performed periodically (about once every 3 months) using the reference tile included with the instrument.

Verification check is simple requiring one measurement to be made and comparing the result obtained with the values indicated on the tile.

If the measured values are within the agreed tolerance then the instrument can be used. If they are outside the tolerance please contact your nearest Rhopoint Authorised Service Representative for advice.
