Welcome to Aumictech, your trusted source for high-precision calibration and repair of Bristol Instruments laser wavelength meters and optical test equipment. Whether you’re in a metrology lab, photonics R&D, or laser manufacturing environment, the accuracy of your optical measurements is critical—and we’re here to make sure your instruments perform to spec, every time.
Our lab in Downingtown, PA offers NIST-traceable, expert-level calibration and repair services for a wide variety of laser wavelength meters from Bristol Instruments, including the popular 671 Series, 771 Series, 871 Series, and other tunable laser diagnostics equipment.
Why Optical Calibration Matters — Especially for Wavelength Meters
Laser wavelength meters, especially those from Bristol Instruments, are designed to measure absolute wavelength, frequency, and linewidth with extremely tight tolerances — often at sub-picometer resolution.
Over time, however, internal interferometers, photodiodes, and calibration references can drift due to:
- Environmental factors (temperature, humidity)
- Optical fiber degradation
- Mechanical alignment shifts
- Aging HeNe or Fizeau reference lasers
This drift can lead to subtle inaccuracies in wavelength readings — which can cause cascading errors in your system design, product validation, or laser tuning.
That’s why periodic calibration and internal verification are critical for anyone using high-resolution instruments like Bristol’s models.
Models of Bristol Instruments We Service
We specialize in full-service calibration, diagnostics, and repair of these Bristol Instruments models:
🔹 671 Series – Laser Wavelength Meter (High Accuracy)
- Absolute wavelength measurements with accuracy up to ± 0.2 ppm
- Commonly used for tunable laser characterization
- 375 nm – 12 μm wavelength range
- Calibration ensures continued traceability and repeatability in photonics labs
🔹 771 Series – High-Speed Wavelength Meter
- Ideal for real-time laser tuning feedback
- Measurement rate: up to 1 kHz
- Requires clean signal path and internal reference validation
- We perform internal cleaning, alignment verification, and sensor calibration
🔹 871 Series – Laser Spectrum Analyzer
- Combines wavelength meter and optical spectrum analyzer
- Calibration includes both absolute wavelength AND spectral response
- We handle both wavelength accuracy and resolution bandwidth calibration
🔹 OSA-201 and similar models
- Older-generation OSAs still in use in telecom and fiber laser labs
- Require specialized parts and alignment processes
- We support legacy instruments with component-level service
If you’re not sure whether your Bristol Instruments model is supported, simply email us at sales@aumictech.com — our technical team will review it quickly.
NIST-Traceable Optical Calibration – What We Do
Our calibration process for Bristol optical meters includes:
- Verification against NIST-traceable gas cell references
- Fiber alignment check and optimization
- Reference laser (HeNe) stabilization and tuning
- Fizeau interferometer verification and cleanup
- Spectral response check using broadband tunable sources
- Temperature-controlled calibration environment
- Detailed calibration certificate with before/after data
We provide a comprehensive digital report, showing the deviation across multiple known wavelength points (e.g., 532nm, 780nm, 1310nm, 1550nm, etc.), including uncertainty and measurement conditions.
Repair Services for Bristol Wavelength Meters
Many wavelength meters experience internal issues that affect performance long before full failure occurs. At Aumictech, we go beyond calibration to offer full diagnostics and repair, including:
- Fizeau interferometer realignment
- Replacement of aging photodiodes and filters
- Cleaning or replacement of fiber collimators
- Repair or replacement of internal reference lasers
- Firmware resets and memory diagnostics
- Power supply and mainboard servicing
After any repair, we fully recalibrate the unit to factory-level accuracy.
Applications and Industries We Serve
Our calibration services for Bristol Instruments are relied on by:
- Photonics research labs
- Semiconductor lithography and laser diode manufacturing
- Tunable laser developers
- Telecom and datacom optical transceiver companies
- Universities and national labs
- Spectroscopy and quantum computing R&D
If your work depends on sub-GHz wavelength precision, you understand how even a few picometers of drift can throw off results. Aumictech ensures your Bristol meter doesn’t become the weak link in your measurement chain.
