Wavelength Meter and Optical Laser Calibration & Repair Services – Aumictech

At Aumictech LLC, we specialize in wavelength meter calibration and repair as well as optical laser source calibration for industry-leading brands including Agilent/Keysight, HighFinesse, Bristol Instruments, EXFO, Photonetics, and Anritsu.

Accurate wavelength and power measurement is critical for telecom networks, R&D laboratories, and optical component manufacturers. Aumictech provides NIST-traceable calibration, advanced diagnostics, and cost-effective repair services, ensuring your wavelength meters and lasers maintain the precision required for DWDM, CWDM, and cutting-edge optical applications.

Technical Calibration Process for Wavelength Meters

A wavelength meter’s precision depends on its etalon, interferometer, or diffraction grating system along with the photodetector calibration. Over time, environmental factors, detector drift, and reference laser misalignment reduce accuracy.

Our calibration procedures include:

• Wavelength Accuracy Verification – Stabilized lasers (HeNe, DFB, or tunable references) used to validate accuracy down to ±0.1 pm or per model specification.

• Power Level Calibration – Adjusting photodetector gain and linearity with NIST-traceable optical power meters.

• Linearity Testing – Ensuring consistent response across the full measurement range (e.g., 600–1700 nm).

• Resolution & Repeatability Verification – Confirming wavelength stability and repeatability across multiple test cycles.

• Environmental Compensation – Calibrating temperature and pressure sensors for stable interferometric measurements.

• Firmware/Software Calibration Updates – Reprogramming internal reference tables with verified values.

Each calibration includes a certificate of traceability to NIST standards, suitable for ISO 17025 compliance.

Optical Laser Calibration and Repair

Aumictech also provides calibration and repair of optical lasers, including:

• Tunable Lasers (CW) – Verification of tuning accuracy, wavelength repeatability, and output stability.

• Fixed Wavelength Lasers – Stabilization and recalibration of reference lasers for test systems.

• Power Accuracy Calibration – Optical power output validated with traceable standards.

• Linewidth and Stability Testing – Ensuring spectral purity for coherent applications.

Common Repair Services for Lasers:

• Internal Reference Drift – Replacing or recalibrating reference etalons.

• Output Stage Damage – Connector, collimator, or isolator replacements.

• Pump Laser Failures – Diode or fiber amplifier replacements with OEM-grade parts.

• Controller & Power Supply Repairs – Repairing or replacing driver electronics, fans, and control boards.

All laser repairs are followed by wavelength and power recalibration to ensure factory-level performance.
