Introducing the Nano Point Scanner

Confocal White Light Profilometry

The NPS Technology

The NPS is an innovative non-contact confocal 3D profilometer measuring altitude in real time, for profile or surface scanning:

  1. The white light LED beam is projected through a beamsplitter and a chromatic lens to the surface of the sample
  2. The reflected light beam from the sample is filtered in a confocal pinhole, isolating one single wavelength in perfect focus
  3. The NPS spectrometer is accurately translating this wavelength into height information and display it visually in the NPS software
  4. Up to 2000 height information per second are acquired in real time creating a profile when moving the XY stage

You can select between two modes: Profile or Surface

NPS Confocal White Light Sensor 

Works on any Type of Surface

The confocal system generates a sharply focused observation plane. Points located above or below the object surface are completely out of focus, so that the type of material does not matter: the sample can be mirror, shinny, reflective or rough - it can be opaque or completely transparent.

Quality and Standards Compliance - ISO

 

White light chromatic confocal technology is ISO certified for roughness measurement and is currently used by many companies and research centers all over the world. 

The NPS allows high precision XYZ axis measurement beyond the limitation of ISO 25178-602 optical depth of field.

High Speed Profile (1-axis scan)

By moving the sample with the high precision motorized XY stage in one axis, the NPS acquires a series of focused points at a chosen interval, creating a fast profile: the measurement of height, distance, radius, line roughness (Ra, Rz, Rt,...) and much more can be done within seconds!

High Resolution Surface (2-axis scan)

By creating a series of aligned profiles, the NPS acquires XYZ information creating a high resolution 3D surface: volume, surface roughness (Sa, Sz,...), complex shape, 3D waviness and much more can be measured.
The duration of the scan is adjusted by the amount of lines, scanning speed and the dimension of the sample!

Multiple measurement possibilities

By combining high precision measurements with advanced metrology software, the NPS will match all your metrology requierements 

PROFILE & MULTI-PROFILE

Automotive sample

The fastest way to execute a measurement! After scanning between two points, the NPS will display the profile: you can then adjust the level, measure horizontal & vertical distances as well as Ra, Rz and Rt measurements.

For advanced measurement, select the desired Hirox Map template inside the NPS menu.
With the new programable multi-profile function, simply execute several individual profiles combined in one single report.

SHAPE & FORMS

Optical lens

Surface shape and geometry can be easily measured: on a spherical object, the measurement results of a curvature can be compared to manufacturing specification for example. Other shapes such as lines, planes, spheres, cylinders or freeform are typical objects that the NPS can measure: length, height, radius, angle, volume and much more. With large measuring ranges up to 4000 micrometer, various shape and forms can be captured and measured.

Measurement of a PCB deformation

Flatness, waviness & coplanarity

FLATNESS, WAVINESS & COPLANARITY Warp, Deformation, Waviness, or Flatness are easily measured on large areas with the Nano Point Scanner! Thanks to XY stage up to 500x500mm, it’s possible to measure defects that can occur from machine or work anomaly, residual stress, vibrations, or heat treatment for example.
Coplanarity is another parameter that requires long distances and high level of Z accuracy. This can be done either thanks to a profile or a surface.

Measurement of Mahr PRN-10 Roughness Standard

Roughness, texture & defects

Surface metrology determines surface topography, which is essential for confirming a surface’s suitability for its function. Surface measurement includes profile roughness (Ra), surface roughness (Sa), surface texture, asperity and structural characterization.

For manufacturing and design purposes, measurement is critical to ensure that the finished material meets the design specification.

The NPS Sensors

The right sensors for your requirements

The NPS System provides a wide range of sensors to achieve seamless highly accurate measurement.
Depending on your application, you can select the best sensors for your needs: small measuring range for highest accuracy and roughness measurement or large measuring range for tall sample and form measurements.

Hirox Maps - advanced metrology software

By combining high-precision measurement with advanced metrology software, the NPS will match all your metrology requierements.

Hirox Maps - Mountains technology!

The Mountains Map 8 technology is the most advanced metrology solution on the market: 

  • Real-time imaging of 3D-surface topography
  • 3D-surface overlays for fast feature location: combination of height color + image intensity from the NPS
  • Removal of data acquisition or sample artefacts
  • Area extraction, level and shape correction
  • Full measurement suite on profiles and 3D data with user and process tracability.

Powerful & simple 

While many functions involve complex calculations, every effort is made to ensure that accessing and using these functions is as easy as possible. Also, once a measurement report has been done, all the parameters used can be easily applied to a new sample with tolerance limits showing in green / red.
Every report can then become a measurement template for fast and easy workflow with fail/pass!

Automatic display of tolerance: angle measurements on a thread

ISO & national metrology standards

Mountains Map has an installed base of 10,000+ licenses worldwide, supports ISO and national metrology standards. Mountains Map works in over 10 languages!

Form & non-measured points removal

The NPS software always exports unprocessed raw data, which can then be filtered in Hirox Maps. You can for example display or fill the non-measured points but also remove the form to keep only the surface

Easy reporting :

  • Easy integration into lab and production environments
  • Export of all numerical results
  • Easy publication
