Noomeo OptiNum

The laser scanning world is highly active at the moment with a steady stream of new products coming on-line. Stephen Holmes looks at the OptiNum from French manufacturer, Noomeo, which offers a new take on the technology

The 3D laser scanning market is changing. Handheld scanners are becoming increasingly popular, not least for their ability to capture 3D forms in a fraction of the time of more traditional devices.

Noomeo’s OptiNum is one of a new breed of devices to hit the market. It’s different to other handheld laser scanners insofar as it doesn’t require the user to place laser targets on the item to be scanned. It is this ease of use that is sure to make it an attractive proposition for non-expert engineers and designers.

Noomeo’s OptiNum uses a combination of white light and video to generate its point cloud data

The scanner is suitable for a wide range of industries, including general reverse engineering and modelling, the mechanical, medical and prosthetics sectors, and even for simple digital archiving of components.

The OptiNum is not a laser scanner, per se. Instead it uses digital image processing technology, a combination of white light and video from its high-definition CCD cameras, to generate its point cloud data.

One of the major strengths of the OptiNum is that it is a lightweight device. At 2kg, it’s lighter than most laptops, making it easy to transport and manoeuvre. However, while it is powered by an in-built battery, it still needs to be connected to a laptop via a USB connection during operation. It would be great to see a wireless version in the future – anyone that has tripped over a laptop power cable will know exactly why.

Using the OptiNum to reverse engineer a mould

The real beauty of the OptiNum is that it is so quick to get up and running. There is no need for the traditional dots, targets or other means of spatial positioning – everything is done automatically without the end user having to waste time preparing the model. According to Noomeo, it uses complex algorithms to position itself in relation to the subject and boasts an accuracy of up to +/- 100μm. While this means it cannot capture as fine a detail as most competitive handheld scanners, it still means it is suitable for many reverse engineering applications.

The recommended volume for scanned objects is from 10cm3 to 1m3. This puts it at the lower end of the scale for handheld scanners, however Noomeo also says the device’s flexibility means it can be used to scan inside larger parts such as aircraft wings, between complex pipeworks, or at the top of high structures.

The scanner comes with an acquisition software application called NumiSoft. This enables simple clean up of the point cloud, automatic meshing and export to ASCII, XYZ, DXF, and STL formats. An optional software tool, NumiSoft +, offers additional functionality including point cloud and mesh import capabilities, and mesh modification, editing and clean up tools and OBJ export.

As a tool for reverse engineering a product or part with speed and ease, the OptiNum is an exciting proposition


The Noomeo OptiNum is an exciting new entrant to the handheld 3D scanning market. It’s incredibly easy to operate, requires little to no setup time, and can be used pretty much anywhere due to its portability. What’s more it only costs €25,000, putting it within reach of many design and engineering firms.

Of course, at this price there have to be some tradeoffs and it should be clear that this is an entry-level device. Accuracy is at the bottom end of the scale for handheld scanners, but as a tool for reverse engineering a product or part with speed and ease, the OptiNum is an exciting proposition.

Comments on this article:

Just a question. In the magazine the price is $995 - which is very affordable, as opposed to E25,000 - which is not so affordable. Which is it?

I contacted the company and the answer is E25,000 unfortunately. Pity. Still, it was designed using CATIA Imagine and Shape and is a very sexy looking piece of kit.

An unfortunate typo during the layout process has left us with a mistake in the print edition - many apologies to all of you who contacted Noomeo hoping to get in on this terrific technology at bargain prices.

We have also apologised to the lovely people at Noomeo, but maintain that everything else in the article is correct and that the OptiNum is a very exciting proposition.

Hope this clears things up!

Actually, the first price rate is unfortunately a mistake introduced in the paper edition. But the reactivity of Stephen permitted a quick correction in the web and pdf edition. This is very much appreciated.

We confirm that the european price of the OptiNum scanner, together with its NumiSoft associated software, is 25.000 € (no VAT). This makes it one of the best quality/price ratio in this category of 3D scanners.

In addition to all the information already given by Stephen, please note that OptiNum offers a really quick return on investment. As you know, it is difficult to optimize complex industrial processes and the introduction of a new device can be a nightmare regarding organization and human resources. OptiNum is different from many others regarding that particular point. One of its strength, relies in its ability to be naturally integrated in any industrial process, as it does not required any structural modifications and no particular skills of people. Therefore, the Optinum 3D scanner perfectly integrates complex applications such as the reverse engineering, rapid prototyping and CAD compare for first piece geometry validation.

Thus feel free to contact us for further information, to assist to a web demonstration of the scanner live, or if you just want a brochure.

See you soon in other exhibitions, like IMAGINA in Monaco (February 1 to 3, 2011) and INDUSTRY in Lyon, France (April 3 to 8, 2011).
