ZEISS / GOM structured light
ZEISS ATOS White Reference Target Dots
Find uncoded white-on-black markers for ATOS Q, ATOS 5 and GOM structured-light systems by measuring volume.
Quick answer: ATOS and GOM Scan 1 structured-light workflows commonly use uncoded white-on-black reference markers. The correct diameter varies with the calibrated measuring volume, optics and image resolution. The example table below gives shopping starting points, not ZEISS-approved model-to-dot pairings.
Use the model-specific reference table below for details. A matching marker diameter does not by itself certify scanner compatibility.
Shop recommended reference targets
Choose a size and format, then follow the product link for current prices and availability. These are genuine Messpunkte product photographs; the selected product variant determines the final size and adhesive.
0.4 mm white markers
Precision matte-coated white dots for fine fields where supported.
0.8 mm white markers
Common candidate for relatively small structured-light fields.
1.5 mm white markers
Reference dots for appropriate medium fields and target-recognition settings.
3 mm white markers
Larger uncoded white dots for suitable wide-field optics.
Premium white sheets vs. uncoated target rolls
Messpunkte offers both formats. For demanding structured-light metrology, we recommend premium matte-coated sheets. Uncoated rolls are an economical alternative for larger scanning projects when the optical workflow permits them.
Premium sheets Recommended
Available sizes: 0.2–8 mm. Premium matte coating reduces unwanted glare and helps deliver consistent optical recognition in precision metrology workflows.
Best for: inspection-grade scanning and measurement repeatability. Standard and strong adhesive choices on appropriate sizes.
Uncoated rolls High-volume alternative
Available sizes: 1.5–12 mm, including 10 and 12 mm sizes for larger measurement fields. More targets per pack typically means a lower cost per dot.
Best for: large-scale target application and volume purchases. Rolls do not have the premium matte coating found on the sheets, so confirm recognition and measurement suitability.
Actual Shopify assortment: sheets 0.2–8 mm; rolls 1.5–12 mm. Roll adhesive options are light or strong. Current pack price and stock are shown on the product page.
Which format is right for my application?
Read the calibrated measuring volume such as MV170, MV350 or MV500 from your ZEISS configuration.
The proposed dot sizes are estimates to narrow the range, never guaranteed specifications.
Follow the target recognition settings supplied with the particular lens and calibration.
These are uncoded white target dots, not the same retro-reflective markers used by T-SCAN hawk.
Scanner models and target compatibility
| ZEISS sensor / measuring field | Illustrative white-dot starting size | Shop example |
|---|---|---|
| ATOS Q MV50–100 | 0.2–0.4 mm | 0.4 mm dots |
| ATOS Q MV170 | About 0.4 mm | 0.4 mm dots |
| ATOS Q MV270–350 | Approx. 0.8–1 mm | 0.8 mm dots |
| ATOS Q MV500 | Approx. 1–1.5 mm | 1.5 mm dots |
| ATOS 5, field ~170–320 mm | Approx. 0.4–0.8 mm | 0.8 mm dots |
| ATOS 5/5X, field ~500–700 mm | Approx. 1.5–2 mm | 1.5 mm dots |
| ATOS 5/5X, field ~1,000 mm | Approx. 3 mm | 3 mm dots |

White-dot sizing and scanner calibration
A smaller measuring volume generally makes finer reference points visible; a larger measurement field may require larger markers. The size examples shown are illustrative and should be checked against the optical sensor, lens, calibration and inspection software. For a detailed method, read the target-size selection guide.
Do you need scanning spray, too?
Reference markers support positioning and scan alignment. ATTBLIME matting spray helps capture optically challenging surfaces. Keep markers clear of overspray so the scanner can recognize them.
Frequently asked questions
Does ATOS Q always use 1.5 mm reference markers?
No. The correct marker size depends on measuring volume, sensor resolution and calibration. Smaller measuring fields can need substantially smaller dots.
Are the table sizes official ZEISS recommendations?
No. ZEISS publishes measuring-volume options; the marker sizes here are illustrative calculations informed by our target-size selection method. Your calibrated software settings take priority.
Are T-SCAN hawk and ATOS reference markers interchangeable?
Generally not. ATOS structured-light registration commonly uses uncoded white-on-black targets while handheld T-SCAN hawk laser workflows use retro-reflective references.
Do I need coded photogrammetry markers?
Some photogrammetry workflows do. Do not confuse coded markers with uncoded reference dots for standard multi-view registration.
When do I use matting spray?
For optically challenging surfaces where coating is appropriate; do not obscure the white marker centers.
What if my measuring volume isn't listed?
Consult the target recognition settings and our white-dot selection guide to estimate candidates before ordering.
