This unit
The EXFO WA-1000 is a precision laser wavelength meter employing a scanning Michelson interferometer with built-in HeNe laser reference standard for absolute wavelength measurement of continuous wave (CW) sources. It delivers ± 1.0 ppm accuracy (± 0.001 nm at 1000 nm) for laser spectral bandwidth below 10 GHz FWHM, with automatic atmospheric correction via integrated temperature and pressure sensors.
Technical Specifications Measurement Principle: Scanning Michelson interferometer comparing input laser interference fringe pattern against internal HeNe reference (± 500 MHz or ± 1 ppm absolute accuracy). Wavelength Ranges (detector/beamsplitter selectable):
Visible (VIS): 400 nm to 1100 nm
Near Infrared (NIR): 600 nm to 1800 nm
Infrared (IR): 1500 nm to 4000 nm Display: Nanometers (nm), wavenumbers (cm⁻¹), or frequency (GHz) in air or vacuum reference. Resolution: 0.001 nm / 0.001 cm⁻¹ / 0.1 GHz. Measurement Rate: 4.0 Hz (VIS, NIR); 2.5 Hz (IR). Optical Input Sensitivity:
VIS/NIR: 20 µW minimum; 2 mW maximum
IR: 1.0 mW minimum; 100 mW maximum Dynamic Range: 400:1 with automatic attenuator (0–2 Optical Density). Environmental Compensation: Continuous refractive index correction for air conditions.
Key Features
Built-in HeNe reference laser (Class 2, 633 nm, 1 mW max) enables continuous self-calibration
Automatic intensity control across wide input power range
Internal temperature and pressure sensors eliminate atmospheric measurement drift
Multiple display units and resolution for research, manufacturing, and telecommunications workflows
Typical Applications Laser source characterization in telecommunications, research laboratories, and precision manufacturing environments requiring traceable absolute wavelength verification.
Compatibility & Integration Interfaces: RS-232 serial (standard); GPIB/IEEE-488 (optional). Inputs: FC/PC fiber connector (FC/APC optional) for VIS/NIR; free-space beam input (2 mm aperture) with red alignment tracer. Outputs: Analog monitor signal (fringes, timing) for oscilloscope display; ± 5 V analog output proportional to wavelength deviation from setpoint.
Exfo WA-1000 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Exfo WA-1000. 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 Exfo WA-1000 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.
