Spectrometer calibration service

This calibration utility computes the wavelengths and resolution of your spectrometer at each data point of the uploaded calibration spectrum. A calibration spectrum is the response of the calibrated spectrometer to a sequence of monochromatic sources, such as the emission lines of gas-discharge lamps. Out-of-the-box support is provided for the most common calibration sources that include HgAr, Ar, Kr, Ne, Xe, He, Br and H gas-discharge lamps. However, if required, a custom set of emission lines can be uploaded and used with the calibration spectrum. The underlying calibration methodology is based on our extensive work in the field of modeling spectrometers and hyperspectral imaging systems.

How does this calibration service work

1. Upload

Record and upload a calibration spectrum and provide some basic information about the spectrometer.

2. Initialize

Use the provide interactive tool to initialize the calibration and optionally fine-tune the input data.

3. Process

Your calibration data will now be analyzed and processed by the automated system.

4. Report

Inspect and download the calibration report as a PDF file and the calibration data as a CSV file.

This Example calibration report was generated for a spectrometer with an approximate wavelength range extending from 385 to 950 nm and a FWH resolution of 2.6 nm. A HgAr gas-discharge calibration source was used to record the calibration spectrum.

Find out more about the methodology

Visit our Knowledge base section where you will find out more about the supported calibration gas-discharge sources and their emission lines. If none of these calibration sources fits your needs, you will find out how to prepare and upload information about your custom calibration source. Here, you will also find a description of the spectrometer model and details about the related quantities, such as the spectrum baseline, tuning curve that maps the data point locations of the calibration spectrum to wavelengths, point spread function and spectral resolution. The Knowledge Base section, will also provide guidance for recording and preparing a high-quality calibration spectrum with suppressed noise and extended dynamic range.
