Independent. Technical. Proven.
East Coast Metrology provides ISO/IEC 17025:2017 accredited laser tracker calibration services performed at your facility or within controlled laboratory environments. Laser tracker calibration is the formal comparison of your instrument against traceable reference standards to determine measurement accuracy and document performance.
Calibration does not imply adjustment unless explicitly required and authorized. All results are documented to support quality systems, audits, and regulatory compliance.
What Calibration Means for Laser Trackers
Calibration is the documented comparison of a laser tracker’s measurement output to known reference standards. The purpose of calibration is to determine whether the instrument is operating within specified tolerances at the time of evaluation.
Calibration:
- Confirms current measurement performance
- Documents accuracy and uncertainty
- Provides traceability to national standards
- Supports ISO 9001 and AS9100 quality systems
Calibration does not certify fitness for use, validate a process, or guarantee future performance. Those determinations remain the responsibility of the equipment owner, consistent with international definitions and standards.

Why Accredited Laser Tracker Calibration Services Are Critical
Laser trackers are used in large scale dimensional measurement, machine alignment, tooling verification, and assembly inspection. In these applications, inaccurate data can lead to misalignment, rework, delayed startups, or safety risks.
Routine calibration:
- Reduces the risk of undetected measurement drift
- Supports confidence in alignment and inspection data
- Protects downstream manufacturing and assembly processes
- Ensures documented compliance during audits
Maintaining a defined calibration interval is a key control in any measurement management system.
Our Laser Tracker Calibration Process
East Coast Metrology performs systematic laser tracker calibration using traceable reference artifacts and controlled procedures.
The calibration process includes:
- Incoming inspection and system identification
- Environmental condition verification
- Distance measurement evaluation
- Angular measurement evaluation
- Volumetric performance assessment
- Adjustment only when required and authorized
- Final calibration documentation
All activities are performed in accordance with ISO IEC 17025 requirements and recorded accordingly. of the equipment owner, consistent with international definitions and standards.
Adjustment and Verification Clarified
If calibration results indicate that a laser tracker is outside specified tolerances, adjustment may be performed when technically feasible and approved by the customer. Adjustment is a corrective action and is not automatically included with calibration.
After adjustment, the system is recalibrated to document post adjustment performance.
Verification or validation activities, when requested, are treated as separate services and are clearly documented to avoid confusion between terms.

What is level calibration and why is it important?
Level calibration verifies the accuracy and stability of a laser tracker’s internal leveling system.
Laser trackers rely on precise leveling to establish a stable reference frame for angular measurements. Even minor level errors can introduce angular bias that increases over long distances.
ECM’s ISO/IEC 17025:2017 calibration process includes a precision level calibration that is not standard in OEM calibration programs. This additional evaluation strengthens volumetric accuracy and ensures foundational measurement integrity.
Level accuracy is critical when performing:
- Turbine Installs
- Machine leveling
- Paper/Steel Mill Roller Alignments
- Structural assembly
- Bridge and infrastructure measurement
- And much more…
How often should a laser tracker be calibrated?
Most standards and quality systems recommend annual laser tracker calibration. However, calibration intervals may vary based on:
- Frequency of use
- Environmental conditions
- Transportation exposure
- Criticality of measurements
- Internal quality requirements
Organizations operating under ISO 9001, AS9100, or NADCAP typically define a fixed annual interval to maintain compliance and minimize risk.
What happens if my laser tracker fails calibration?
If a laser tracker is found outside specified tolerances:
- ECM documents the As-Found condition.
- The customer is notified before any adjustment is performed.
- Adjustment is completed only when technically feasible and authorized.
- The system is recalibrated to document As-Left performance.
This process preserves data integrity while restoring system performance.
How long does laser tracker calibration take?
Typical turnaround time is less than one week for most laser tracker calibration services.
ECM also offers:
- Expedited service options
- On-site fleet scheduling
- Rental systems to reduce operational downtime
Does ECM offer laser tracker repair services?
Yes. ECM provides advanced diagnostic and laser tracker repair services when technically feasible.
Our technicians have extensive experience evaluating:
- Compensation table errors
- Mechanical instability
- Optical degradation
- Ranging system performance
Unlike some OEM service models that replace assemblies, ECM performs root-cause evaluation to determine the most technically appropriate solution.
Does ECM service legacy laser tracker units?
Yes. ECM will calibrate and repair systems that are no longer supported by the OEMs.
Our service centers specialize in repairing older units. Typical failures may include:
- Impact damage
- Cable repairs (inside and out)
- Zenith/Azimuth boards
- Laser Control Board
- Power Supply
- Lidar / PSATL
Typical service models will replace entire assemblies, ECM performs root-cause evaluation to determine the most technically appropriate solution, saving our clients large expenses.
