This unit
The Burleigh WA-2500 VIS/NIR/IR Wavemeter is a precision instrument for accurate wavelength measurement of continuous-wave laser sources across the visible, near-infrared, and infrared spectral regions. Built around a compact scanning Michelson interferometer and high-resolution Moiré gauge, it delivers ±1 part in 10,000 accuracy with interchangeable detectors for broad spectral coverage. The wavemeter measures tunable lasers including dye, Ti:Sapphire, and diode lasers with coherence lengths down to 150 GHz linewidth and extends to 3000 GHz with Auto-Resolution adjustment.

Burleigh WA-2500 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Burleigh WA-2500. 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-2500 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.
