Photonetics Walics 3651HR12 Optical Spectrum Analyzer – Professional Repair, Optical Alignment & NIST-Traceable Calibration

We provide expert repair, maintenance, and calibration services for the Photonetics Walics 3651HR12 Optical Spectrum Analyzer, a precision instrument widely used for high-resolution spectral analysis in fiber optics, photonics, and laser research. Known for its high dynamic range, narrow resolution bandwidth, and advanced wavelength accuracy, the 3651HR12 remains a critical tool in R&D labs and optical component manufacturing. If your unit is failing to boot, producing inaccurate spectral readings, or showing signs of optical or electronic drift, our technicians can restore it to peak performance using OEM-grade methods and NIST-traceable calibration.

Our Repair & Calibration Process

Complete System Diagnostics
Every 3651HR12 unit undergoes comprehensive evaluation to test:

  • Wavelength accuracy and spectral resolution

  • Optical signal detection and dynamic range performance

  • Sweep speed and span consistency

  • Internal photodetector health and gain response

  • Input port integrity and fiber connector condition

  • Control panel or remote interface (GPIB/RS232) functionality

  • Boot-up sequence and onboard software integrity

We use certified laser sources and test signals to replicate real-world conditions and detect subtle internal issues affecting accuracy or repeatability.

Common Problems We Repair

  • No optical signal or low sensitivity

  • Incorrect or drifting wavelength measurements

  • Frozen display, unresponsive UI, or boot-up failure

  • Faulty photodetector, amplifier, or filter circuits

  • Misalignment of internal optics or scanning mechanism

  • Damaged input fiber connectors (FC/APC, SC, etc.)

  • Communication interface errors (GPIB/RS232)

  • Internal power supply instability or noisy operation

Component-Level Repair & Restoration
We perform deep-level electronic repair, including:

  • Replacement of failed capacitors, op-amps, logic ICs, and regulators

  • Repair of photodetector boards and signal amplification stages

  • Restoration of sweep driver and grating control circuits

  • Power supply reconditioning and stabilization

  • Repair of damaged display modules and front panel controls

Optical Path Cleaning & Realignment
Accurate spectrum analysis depends on a precisely aligned and clean optical system. We:

  • Clean and realign internal lenses, mirrors, and beam splitters

  • Inspect and calibrate the diffraction grating and scanning mechanisms

  • Test and clean fiber input ports to ensure proper coupling and low insertion loss

Firmware & System Function Testing
We verify and, if needed, restore system firmware. Functional tests include:

  • Internal self-test sequences

  • Sweep calibration and span control

  • Output response and spectral trace validation

  • Remote control via GPIB or serial interface

NIST-Traceable Calibration
Following repair, each unit is recalibrated using NIST-traceable optical reference sources, including:

  • Wavelength calibration with certified laser sources

  • Spectral resolution and repeatability verification

  • Dynamic range and trace noise floor measurement
    A detailed calibration certificate with before/after data is included with each unit.
