Frequently Asked Questions

FAQ – 3D measurement, optical and touch probe technologies

1- How does optical measurement work?

Optical measurement is a non-contact method that uses cameras or laser sensors. Unlike contact probes, it does not touch the measured object, is fast, does not damage the part, and can capture complex shapes and fine details.

2: What is multisensor measurement?

A modern 3D measurement method that combines optical, tactile, and laser sensors in one machine. It enables comprehensive quality inspection without moving the part between devices.

3. What are the advantages of optical measurement?

It is non-contact, avoids deforming flexible parts (plastics, rubber), no fixturing is needed, 2D measurement is very fast, laser probes offer high speed, and cameras capture tiny features that tactile probes cannot.

4. What are optical measurement systems used for?

Ideal for inspecting complex parts, hard-to-reach areas, and fine details. They deliver higher accuracy, faster measurements, and lower costs. Widely used in automotive, aerospace, engineering, and medical industries.

5. What outputs does optical measurement provide?

Provides accurate data on shape, dimensions, and surface quality. Outputs include color deviation maps, tolerance reports, and CAD model comparisons. Reports may also include camera images for visual assessment.

6. What materials and surfaces can be measured optically?

Suitable for metals, plastics, glass, ceramics, composites, and rubber. With the right sensors, it can also measure shiny and transparent surfaces.

7. What is the accuracy of optical measurement systems?

They achieve sub-micron accuracy, depending on the machine type, technology, and measurement conditions.

8. What is the difference between optical and contact measurement?

Optical measurement is non-contact, using a camera or laser, while contact measurement uses a probe that physically touches the part.

9. Can optical measurement replace contact measurement?

In many cases yes – especially with flexible parts, delicate features, or when a fast dimensional check is required.

10: What is 3D scanning?

A process of rapid and accurate acquisition of 3D data from an object. Used for CAD comparison, reverse engineering, prototyping, and 3D modeling.

11. How does reverse engineering with a 3D scanner work?

The object is non-contact scanned to create an accurate 3D model, which can be edited and exported into CAD software.

12. What is the difference between a 2D profile projector and a 3D optical machine?

A 2D profile projector measures only outline dimensions in one plane, while a 3D optical machine provides full 3D information, including heights, geometric tolerances, and feature positions.

FAQ - Our Measurement Systems and Services

1. What measurement systems and brands do you offer?

We supply optical and multisensor systems, 3D scanners, photogrammetry, laser and tactile systems, 2D profile projectors, 3D measuring arms, shaft measurement systems, CT scanners, and also hand tools such as calipers, micrometers, indicators, and height gauges.

2. Can you help me choose the right system or software?

Yes – we provide expert consultations, recommendations, and demonstrations on customer samples.

3. Can I try a system before purchase?

Yes – we offer trial measurements and live demonstrations.

4. Do you provide system installation?

Yes – we handle installation, commissioning, and operator training directly at the customer site.

5. How do I know it’s time to replace a system instead of repairing it?

When repairs become frequent, maintenance costs rise, and accuracy no longer meets production requirements, it is more effective to invest in a new system.

We provide warranty and post-warranty service, including original spare parts, with service performed on-site if needed.

7. What are the benefits of a service contract?

Guarantees priority response within 24 hours, regular maintenance, and lower prices for calibrations, repairs, and parts.

8. Can spare parts be ordered from you?

Yes – we stock original parts (OGP, Micro-Vu, and others) for fast availability.

9. Do you perform accredited calibration?

Yes – we operate an ISO/IEC 17025:2018 accredited calibration laboratory.

10. How often should measurement systems be calibrated?

Typically once a year, more frequently depending on usage.

11. Do you provide training?

Yes – operator and software training, including for new staff.

12. Do you provide remote technical support?

Yes – phone, online support, and remote diagnostics.

13. Do you sell accessories?

Yes – such as probes, optical components, adapters.

With proper care, the lifetime of OGP SmartScope systems is over 15 years.

15. Do you offer refurbished or stock systems?

Yes – refurbished and stock systems at attractive prices.

16. What types of 3D scanners do you offer?

Handheld and stationary scanners from SCANOLOGY and OGP, suitable for industrial applications, quality control, and reverse engineering.

17. What is the delivery time for systems?

Stock systems – immediately, others depending on manufacturer lead time (usually weeks).

18. Can systems be financed via leasing?

Yes – we prepare customized financing solutions.

FAQ – Machine Calibration

1. What is calibration of measurement systems?

A process of comparing the system against standards to verify accuracy and compliance with norms. It ensures traceability, accuracy, and reliability of measurements.

2. Why calibrate measurement systems?

To maintain measurement accuracy and reliability, and to meet quality and audit requirements.

3. Which systems does DEOM calibrate?

Accredited calibration of optical and multisensor machines, probes, 3D CMMs, as well as hand tools such as calipers, micrometers, and indicators.

4. Why choose accredited calibration?

It provides an internationally recognized certificate and ensures calibration is performed according to standardized procedures.

5. How does calibration with you work?

Calibration begins with handover of the device directly at the customer’s site. We measure calibrated standards on the instrument, compare the measured data with calibration values, and evaluate the deviations. After completion, the customer receives a protocol or certificate, along with the instrument ready for further use. The service also includes reminders of the next calibration date.

6. How often should systems be calibrated?

At least once per year, more frequently for intensive use or after mechanical impacts.

7. What is the difference between factory and accredited calibration?

Factory calibration checks functionality according to manufacturer procedures, while accredited calibration follows international standards and provides a recognized certificate.

8. How can stable conditions for measurement be ensured?

By controlling temperature, humidity, and environment, ideally with monitoring systems.

FAQ – Hand Measuring Tools

1. What are hand measuring tools and what are they used for?

Basic hand measuring tools – calipers, micrometers, dial indicators – used in workshops, labs, and production for fast and accurate measurements.

2. How is calibration of hand measuring tools performed?

By comparing them with reference standards in an accredited lab or on-site, followed by issuing a calibration certificate.

3. What are the most common errors when using hand measuring tools?

Typical errors include incorrect zeroing, excessive force, misreading the scale, and measuring on dirty surfaces.
