This unit
The Burleigh WA-20 Wavemeter is a precision instrument for absolute wavelength measurement of continuous wave lasers across the ultraviolet to mid-infrared spectrum. Built around a scanning Michelson interferometer and an integrated HeNe laser wavelength standard, it delivers traceable measurements without external reference sources. The instrument automatically determines laser wavelength with high accuracy, making it essential for laser tuning, spectral characterization, and drift monitoring applications.

Burleigh WA-20 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Burleigh WA-20. Calibration covers absolute wavelength accuracy at multiple reference points across the full measurement range, frequency accuracy, wavenumber accuracy, and multi-wavelength channel spacing measurement accuracy. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Burleigh WA-20 faults: interferometer alignment drift, reference etalon or HeNe laser end-of-life, InGaAs detector sensitivity loss, fiber input connector damage. Fizeau interferometer-based instruments (Agilent 86120B/86122A/C) most commonly develop interferometer alignment drift and InGaAs detector degradation over time. Burleigh WA-series scanning Fabry-Perot instruments most commonly fail due to reference HeNe laser end-of-life. Both types are fully repairable with post-repair wavelength accuracy verification.
