At Aumictech, we provide expert-level repair and calibration services for Bristol Instruments Optical Spectrum Analyzers, including the high-performance 871 Series. As a trusted partner to photonics manufacturers, telecom labs, and laser R&D facilities, we understand that even minor inaccuracies in optical spectrum measurements can lead to major setbacks in your development cycle, product testing, or field deployment.
Our technical team specializes in both hardware repairs and NIST-traceable optical calibration for Bristol OSAs. Whether your unit is drifting, failing to boot, or delivering noisy or unreliable spectrum data, we restore it to factory-grade accuracy — or better.
About the Bristol 871 Series Optical Spectrum Analyzer
The 871 Series from Bristol Instruments is widely respected for its ability to accurately measure wavelength and optical power of CW lasers, tunable sources, and other narrow-linewidth photonic systems. It combines the precision of a laser wavelength meter with the functionality of an optical spectrum analyzer, making it essential for:
- Laser diode characterization
- DWDM channel spacing validation
- Tunable laser monitoring
- Wavelength stability testing
- Spectral purity assessment
The 871 Series typically offers:
- ±0.2 ppm wavelength accuracy
- Up to 100 Hz measurement rate
- Measurement range: 375 nm – 2.6 µm (model-dependent)
- Simultaneous spectrum and wavelength output
This level of performance, however, requires routine calibration and occasional repairs to maintain accuracy and reliability.
Common Issues with the Bristol 871 Series – What We Repair
With time and usage, Bristol OSAs can develop a range of faults that impact their functionality and accuracy. At Aumictech, we address:
🔧 Inaccurate Wavelength or Power Readings
- Due to aging internal optics, photodetector sensitivity loss, or drift in reference lasers
- We replace affected components and recalibrate to factory specs
🔧 Failing or Unstable Internal Reference Laser
- A degraded HeNe or DFB reference can destabilize all measurements
- We provide precise replacements and realignment services
🔧 Software & Interface Issues
- Unresponsive UI, USB communication failures, or data export problems
- We test, repair, and reconfigure embedded firmware and interfaces
🔧 No Spectrum Display / Blank Output
- Often caused by faulty interferometer signals, photodiode issues, or fiber input damage
- We restore optical paths, recondition fibers, and replace failed detectors
🔧 Mechanical and Environmental Degradation
- Includes fan failures, thermal control issues, or physical misalignment from transport
- We stabilize internal systems and reinforce component mounts
After each repair, we perform a full calibration and quality test, ensuring your OSA is ready for deployment in any precision-focused photonics environment.
Full Calibration Services – Certified and Traceable
Calibration of a Bristol OSA isn’t just about restoring factory accuracy — it’s about ensuring your entire optical test system remains traceable, compliant, and reproducible.
Our calibration process includes:
- Wavelength accuracy verification using gas cell standards and broadband sources
- Spectral response validation across the full operating range
- Optical power linearity and sensitivity check
- Resolution bandwidth (RBW) accuracy testing
- Noise floor and dynamic range measurement
- Temperature-stabilized environment to minimize drift
- Before-and-after calibration reports
- NIST-traceable certification with all units
We support single-wavelength, swept, and broadband tunable source calibrations, customized for your specific lab use cases.
