Your Trusted Interferometer Calibration Provider
Micro Precision is an ISO/IEC 17025:2017 accredited calibration provider delivering NIST-traceable interferometer calibration through a network of more than 50 laboratories nationwide. Every interferometer calibration performed by Micro Precision is backed by ISO/IEC 17025:2017 accreditation and NIST-traceable measurement standards, giving aerospace, defense, medical, automotive, and manufacturing quality programs certificates of calibration that satisfy internal audits and customer requirements. Interferometers demand exceptional measurement stability because they underpin dimensional metrology, surface form testing, and displacement measurement used throughout precision manufacturing and research environments. Micro Precision’s accredited technicians calibrate laser interferometers, Michelson interferometers, Fizeau interferometers, and related optical measurement instruments against NIST-traceable reference standards, documenting each result on a certificate of calibration.
Our lab network gives customers access to consistent accredited calibration regardless of location, supporting quality management systems that require documented traceability under ANSI/NCSL Z540.3. Aerospace, defense, medical device, automotive, and general manufacturing organizations rely on Micro Precision for interferometer calibration because our accreditation, documentation, and lab capacity scale with enterprise calibration programs. Every certificate issued ties measurement results back to national standards, giving quality managers, metrologists, and procurement teams the documentation needed to pass audits and maintain compliant calibration intervals.
Why Interferometer Calibration Matters
Interferometer calibration matters because even small drift in reference optics or laser sources can shift measurement results without an obvious fault indication, creating compliance gaps under ANSI/NCSL Z540.3 and risking nonconforming product reaching customers. Uncalibrated or drifted interferometers can allow measurement error to go undetected in dimensional and surface-form inspection, a real risk for aerospace, defense, and medical device programs that depend on traceable measurement for product acceptance. ISO/IEC 17025:2017 accredited calibration gives quality managers and auditors documentation recognized industry-wide, supporting audit readiness and measurement confidence.
Ensure Accurate Interferometer Calibration
Ensuring accurate interferometer calibration means following a documented receive, inspect, test, adjust, and certify workflow: technicians inspect the instrument, test it across its measurement range against NIST-traceable reference standards, make adjustments where possible, and record results on a certificate of calibration. Every interferometer calibration follows this documented workflow, with results issued on a certificate of calibration that ties measurement data back to NIST-traceable reference standards. Standard and faster turnaround options are available so calibration can align with production schedules and audit deadlines.
Our Calibration Options
Micro Precision offers both in-lab and on-site interferometer calibration, each backed by NIST-traceable reference standards and a certificate of calibration for every instrument.
In-Lab Calibration — Full access to laboratory-grade reference standards and environmental controls, ideal for vibration- and temperature-sensitive instruments like laser and Fizeau interferometers.
On-Site Calibration — For interferometer systems integrated into production lines or otherwise impractical to ship; technicians bring reference standards directly to your facility.
Faster Turnaround — Available alongside standard service for audits, production deadlines, or urgent quality holds.

Frequently Asked Questions
Interferometer calibration frequency depends on usage intensity, manufacturer recommendations, and the requirements of the quality management system in place. Most quality programs following ANSI/NCSL Z540.3 establish calibration intervals based on instrument stability history and risk of measurement drift. Micro Precision helps customers document and maintain calibration intervals appropriate to their interferometer’s application and accreditation requirements.
Interferometer calibration involves inspecting the instrument, testing it against NIST-traceable reference standards, adjusting it when needed, and documenting results on a certificate of calibration. Micro Precision technicians follow a receive, inspect, test, adjust, and certify workflow for every interferometer, ensuring measurement results are traceable to national standards before the instrument is returned to service.
Interferometer calibration cost varies based on instrument type, service level, and whether in-lab or on-site calibration is required. Micro Precision provides calibration quotes based on the specific interferometer model and service level requested. Contact Micro Precision for a customized calibration quote reflecting your equipment and documentation needs.
Interferometer calibration programs commonly reference ANSI/NCSL Z540.3 for calibration requirements and rely on NIST-traceable measurement standards to establish traceability. Micro Precision performs interferometer calibration under ISO/IEC 17025:2017 accreditation, issuing certificates of calibration that document traceability to national measurement standards for audit and compliance purposes.
Laser interferometers can be calibrated on-site when removal from a production or metrology environment is impractical. Micro Precision technicians travel to customer facilities with NIST-traceable reference standards to perform on-site calibration, issuing the same certificate of calibration documentation provided for in-lab service.
NIST-traceable interferometer calibration means measurement results are linked through an unbroken chain of comparisons back to National Institute of Standards and Technology reference standards. Micro Precision issues NIST-traceable certificates of calibration for interferometers, giving quality managers and auditors documented evidence that measurement results meet national traceability requirements.
Interferometer calibration turnaround depends on instrument type, service level, and current laboratory workload. Micro Precision offers standard and faster turnaround options so customers can align calibration scheduling with production and audit deadlines.
