Which Profilometer? Choosing a NANOVEA 3D Optical Profilometer

Every NANOVEA profilometer measures with the same white light chromatic confocal technology, so the choice comes down to the base around the sensor: whether samples come to the instrument or the instrument goes to them, how large an area must be scanned, how fast, and whether a point sensor's accuracy or a line sensor's coverage matters more. This guide walks through those questions and points to the model that answers them.

Start with the sample

The fastest way to the right profilometer is to describe the samples: their size, whether they can be brought to a laboratory, how rough or tall their features are, and how many need measuring. Because every NANOVEA profilometer uses the same chromatic confocal sensors, measurement quality is not the deciding factor between models. The base around the sensor is.

Benchtop or portable

If samples come to the instrument, a benchtop model gives motorized stages, automation and the largest scan areas. If the instrument must go to the sample (large or fixed parts, welds, structures, field research, objects that cannot be cut or shipped), choose a portable model. The JR25 weighs 5.3 kg and travels as hand luggage; the JR100 scans 100 x 100 mm and can carry a high-speed line sensor.

Scan area and speed

Model Type X-Y travel Max speed Sensors
PS50 Compact benchtop 50 x 50 mm 20 mm/s Point
ST400 Standard benchtop 200 x 150 mm 40 mm/s Point or line
ST500 Large-area benchtop 400 x 400 mm 200 mm/s Point or line
JR25 Portable 25 x 25 mm 20 mm/s Point
JR100 Portable 100 x 100 mm 20 mm/s Point or line

Choose the stage for the largest area you need to scan in one piece; continuous, stitching-free scans avoid the errors that image stitching adds. For samples beyond 400 x 400 mm, NANOVEA builds larger custom bases around the same sensors.

Point or line sensor

A point sensor measures one point at a time with the highest accuracy, down to 1.9 nm height repeatability on the PS1, and measures slopes up to 87°. It suits fine finishes, steep features and precise profiles. A line sensor projects 192 points at once and acquires up to 384,000 points/s, so it covers large areas in fewer passes; it suits mapping, inspection of many parts and large surfaces. Line sensors fit the ST400, ST500 and JR100.

Sensor range

Pick a sensor whose height range exceeds the surface’s height variation, with the finest resolution that still covers it. Point sensors run from 110 µm (PS1) for polished and fine finishes to 24 mm (PS6) for rough castings, textures and tall features; line sensors run from 200 µm to 3.9 mm. Sensors are interchangeable, so one instrument can be used with both a fine and a coarse sensor.

Beyond the standard range

  • Nanoscale lateral resolution: the AFM Pro adds an atomic force microscope (1.7 nm lateral resolution over 110 µm) to a chromatic confocal profiler, for polished and nanostructured surfaces.
  • Production: the in-line profiler installs chromatic sensors in the line at more than 1,300,000 points/s, with pass/fail decisions per sensor or on the average of all sensors.
  • Measurements: see what each model can report, from roughness and texture to step height, volume, form and flatness.

Test before you choose

The surest way to choose is to measure real parts. NANOVEA’s surface profiling laboratory measures your samples on the same instruments it sells, with the sensor and settings that suit them, and the results show which configuration your application needs.

Six questions that pick the model

  • Portable or benchtop?

    If parts cannot come to the lab, start with the JR25 or JR100.

  • How large is the sample?

    Scan area sets the base: 50 x 50, 200 x 150 or 400 x 400 mm.

  • Point or line sensor?

    Point for the highest accuracy, line for large areas in fewer passes.

  • What height range?

    The sensor's range must exceed the surface's height variation.

  • Nanoscale roughness?

    AFM-level lateral resolution on polished surfaces: AFM Pro.

  • On the production line?

    Sensors installed in the line, with pass/fail decisions.

Frequently asked questions

Do NANOVEA profilometers differ in measurement quality?

No. Every model uses the same white light chromatic confocal sensors, so a given sensor measures the same way on a PS50, an ST400 or a JR25. The models differ in the base: stage size and speed, Z travel, portability, and whether a line sensor can be fitted.

Point sensor or line sensor?

A point sensor measures one point at a time with the highest accuracy, down to 1.9 nm height repeatability on the PS1. A line sensor projects 192 points at once and acquires up to 384,000 points/s, so it covers large areas in fewer passes. Line sensors fit the ST400, ST500 and JR100.

Which sensor range do I need?

One whose height range exceeds the height variation of the surface, with the finest resolution that still covers it. Point sensors range from 110 µm (PS1, for fine finishes) to 24 mm (PS6, for rough or tall features); line sensors from 200 µm to 3.9 mm. Sensors are interchangeable, so one instrument can be used with more than one.

When should I choose a portable profilometer?

When the part cannot come to the laboratory: large or fixed components, welds, structures, field samples, objects that cannot be cut. The <a href="/instruments/jr25/">JR25</a> weighs 5.3 kg and scans 25 x 25 mm; the <a href="/instruments/jr100/">JR100</a> scans 100 x 100 mm and can carry a line sensor. Both also work as benchtop instruments.

What if my samples are larger than 400 x 400 mm?

NANOVEA builds larger custom bases around the same sensors for big samples. <a href="/contact-sales-form/">Contact NANOVEA sales</a> with the sample size and what needs measuring.

Do I need an AFM?

Only when lateral resolution at the nanometre scale matters, for example roughness of polished or nanostructured surfaces over areas of tens of micrometres. The <a href="/instruments/afmpro/">AFM Pro</a> combines an AFM with a chromatic confocal profiler, so the larger-scale measurement stays on the same platform.

How much does a NANOVEA profilometer cost?

It depends on the base, the sensors and the options. The PS50 is the most affordable benchtop; the ST400 and ST500 add line sensors and larger, faster stages. <a href="/contact-sales-form/">Contact NANOVEA sales</a> for a quote on the configuration that fits your samples.
