  • Page 4: Storage And Handling

    Storage and Handling This instrument contains precision optics and electronics. You should • therefore avoid knocking or dropping the device as the resulting impact could cause serious damage. In some circumstances the optical components in the instrument could • become misted as a consequence of temperature change. It is recommended that the instrument is not used until it has stabilised to ambient temperature.

  • Page 5: About The Optimap™ Psd

    About the Optimap™ PSD Optimap™ PSD – The technology Optimap™ PSD is an advanced portable handheld instrument capable of performing fast, full field 3D surface measurements. Using an optical measurement technique known as Phase Stepped Deflectometry (PSD) it objectively measures and characterises many aspects of surface quality including texture, waviness and local defects including orange peel, inclusions, dents and scratches.

  • Page 7: Power

    Power The Optimap™ PSD is powered by an integrated high capacity lithium ion battery. Fully charged the instrument will operate for 4 – 8 hours depending on use. A mains powered battery charger is provided with the unit allowing it to be fully charged, when connected to the units charger input (4), in under 3 hours.

Range Selectable as Sample Viewer either curvature (K) or texture (T) Instrument Settings Measurement Direction Measurement Number Project Name Series Texturemap window The touch sensitive icon based measurement screen provides operation and setup of the device.
  • Page 9 The measurement direction indicator at the lower left of the screen indicates the axis in which the measurement data, including texturemap image, is displayed. This indicator is not touch sensitive and is there only for indication purposes. The Optimap can be configured to display the image in single (X or Y) or dual axis (X+Y) directions.
  • Page 10 A reflective model is suitable for surfaces with a mid to high gloss finish (>30GU) e.g. automotive topcoats, clearcoats etc., metals, by default the Optimap will automatically select this setting. A dull model is suitable for surfaces with a mid to low gloss finish (10-30 GU) e.g. e- coats.
  • Page 11 Once set the display will change to - Up / Down Select Selection Exit A reflective model is shown, alternatively Extra Dull or Dull will be displayed if selected. Press the Select icon, the display will change to - Use the keyboard to enter the name of the project, press Enter to save.
  • Page 12 The display will change to - During this step it is essential that the Optimap is left on the surface being measured as it optimises the optical configuration using the reflected light from the surface. Failure to observe this will result in the Optimap making incorrect measurements. Once completed the screen will return to the main measurement screen with the project name entered being displayed in the Project Name indicator.
  • Page 13 Open Project – By pressing this icon previously stored projects can be selected and recalled for display using the Up / Down selection icons. Transfer Project - Results can be transferred to a USB memory device when inserted in the instrument. Pressing the icon transfers the data. if no memory device is present an error message will be displayed.
  • Page 14 Iteration Screen Previously stored results can be opened or deleted by pressing the Measurement Name indicator on the Main Measurement Screen Operation of this screen is the same as the Project and Series screens. Screens change in the same way as shown previously Returning to the Main Measurement Screen: Results Window Operate...
  • Page 15 To the right of the screen there are three icons, Operate, Sample Viewer and Instrument Settings. Operate To make a measurement, press the Operate icon. Measurement time takes approx. 9 seconds following which measurement data is displayed. The measurement number indicator will increment by one as each measurement is made.
  • Page 16 Sample Viewer – Y Sweep Projects a fringe pattern onto the surface in the Y direction. Useful for pre - measurement directional analysis of texture and / or defects. White screen Illuminates the entire surface.
  • Page 17 Sample viewer – Live View Provides a live view of the sample surface allowing the Optimap to be accurately positioned on the area of interest. Instrument Settings Pressing the Instrument Settings icon accesses the Settings Menu for configuration of the Optimap. There are six icons in this menu. Language Date Time...
  • Page 18 Pressing the Language icon allows different languages to be selected. The Optimap has four languages available – English, German, French and Spanish. Languages are sequentially selected and displayed after each press. Pressing the Date icon allows the date to be set Press the date required in the calendar and Exit to save.

  • Page 22: Measurement Principle

    Measurement Principle Phase Stepped Deflectometry (PSD), a white light optical technique, uses a periodic pattern with a sinusoidal waveform to measure the profile or curvature (K) of a surface. The waveform is presented to the surface using a high resolution display and the reflected pattern captured by a high resolution camera.
  • Page 23 As an overall rating, Total curvature (K), is used to represent the SD (sigma) of curvatures falling within the range 0.1 – 30.0mm. As a totally flat surface would have no variation in curvature, higher curvature values indicate that there are more structures present on the surface at that particular wavelength range.
