Can DotScan (Chromatic White Light) evaluate Surface Texture?

[[Je...]]

Is DotScan, a chromatic white light sensor, able to evaluate surface texture?

The reason I ask is because chromatic white light sensors tend to perform well with surface texture measurement tasks.

DotScan's non-contact modality makes it excellent tech to employ in medical device manufacturing and other situations where tactile stylii like ROTOS are not an option.

Thoughts?

Depends on how fine, but I've personally tested ours and been able to detect surface finish down to around 3-4µm Ra.

Tell me more.

Which software do you use for the measurements?  How do you set up surface finish characteristics in the software?

Calypso can natively handle surface finish - this was mainly always done via the Rotos sensor, but now Calypso allows for surface finish analysis without the need of a Rotos.

Are you referring to the older version of the DotScan. I think it was called CWS prior? We have two 543 O-inspects

with DotScans and there is no adjustment/setting for material type as there was with the older version.

I stand corrected. Adjustments are there.

Agreed — the lack of an edit/delete function is frustrating. Hopefully, an update is already queued up for the forum platform.
 

On the topic of DotScan:

From what I’m hearing through Zeiss contacts, DotScan adoption is gaining momentum. I suspected the slower uptake early on was less about the technology’s limitations and more about limited awareness — both in the marketplace and internally — of its true capabilities.

There’s an enormous opportunity here. The demand for non-contact surface texture (Ra) measurement is real — especially when integrated alongside dimensional inspection, not isolated to standalone systems.  Zeiss could capture this market segment before others further entrench themselves.

It’s frustrating to see Keyence dominate search results in this space, knowing Zeiss has the ingredients to build a far superior solution.

We use it for very small and complex geometry on a flexible part. There is no way we could measure this part

using tactile. Even a camera would only be able to measure the 2d stuff. It is also extremely fast with very high point density.
