It’s almost spring break, and the SpectraWizard is ready for some rest and re-calibration!
Is it time for your spectrometer to take a spring break getaway? Give your instrument the reset it deserves!
Spring is about renewal and reset. While you’re refreshing labs, re-calibrating processes, and planning for Q2, your spectrometer deserves the same attention. This March, use promo code BOGO-RECAL to receive a free re-calibration in 2027! Don’t miss out, save today.

StellarNet offers both wavelength (x-axis) recalibrations and intensity re-calibrations (y-axis). All StellarNet spectrometers have an x-axis calibration from our factory. If your system was also calibrated for radiometric measurements, then it has had an one of our intensity calibration services. We offer irradiance (W/m^2), radiance (W/m^2/sr), or radiant flux (W).

What does x-axis re-calibration service include?

✔ connectivity and data transfer evaluation
✔ detector analysis (hot pixel, baseline, photodegradation, dust/debri or contamination)
✔ evaluation of optical bench (slit, filters, stray light and sensitivity performance)
✔ x-axis (wavelength) recalibration to traceable standards

What does a y-axis intensity re-calibration service include?

Consider adding capability with different y-axis calibration types irradiance (W/m^2), radiance (W/m^2/sr), or radiant flux (W). Low light calibrations are also available.

Typical calibration turnaround is 1-2 weeks with RUSH services available.

New Advanced Calibration Evaluation Services

StellarNet is now offering a new “as-is and as-found” advanced evaluation service which provides additional testing and documentation showing:

📌 state of previous calibration service compared to the reference lamp
📌 state of the new calibration once the system is calibrated to the lamp

If you are in a regulated environment (ISO, FDA, etc) – be sure to add the advanced calibration documentation to your recalibration service! Check out an example evaluation document here

Prevent Downtime Before It Happens

Re-Calibration is more than routine maintenance — it’s a proactive diagnostic check. It helps identify early detector degradation, fiber or connector wear, and optical contamination before they become serious issues. Catching problems early prevents unexpected downtime, costly repairs, and production interruptions.

Stay in Compliance

For laboratories operating under ISO 9000, ISO/IEC 17025, GMP/cGMP, or FDA-regulated environments, annual Re-Calibration provides documented, traceable verification of instrument performance. This supports regulatory compliance, maintains quality standards, and simplifies audits with confidence.

Restore Wavelength and Spectral Accuracy

Over time, even precision optical systems experience subtle drift, including wavelength alignment shifts, detector dark current changes, and stray light performance degradation. Annual Re-Calibration can restore your spectrometers to factory specifications, ensuring accurate peak positions, stable baselines, and reliable measurement performance. If there is a larger issue our technical team can easily evaluate and provide you with a repair estimate.

Radiometric Re-Calibration

If your instrument is used for absolute intensity measurements, radiometric calibration is critical. Detector responsivity changes, optical fiber aging or cracking, cosine corrector degradation, and optical contamination can all introduce radiometric drift. Without Re-Calibration, intensity measurements may no longer represent true physical units — compromising data integrity and traceability. Or perhaps you’d like to add additional capability. While your spectrometer is in the shop consider irradiance, radiance, radiant flux or low light level calibrations.
